Quang is a marketing / sales intern who is with Scuba Cat for a 6 month placement from his university in Holland. As part of his internship he is receiving dive training up to Advanced open water through Scuba Cat. This is a great way to be involved in the industry and understand more about what you are trying to market. This though was more of a challenge for Quang than previous interns as he was unable to swim at the time he joined us.

Quang worked really hard, learnt to swim and snorkel and too 3 discover scuba dives prior to taking his open water course, this is his story of the day he got certified in his own words…….

Taking a deep breath, Breathing out, Opening my eyes, Seeing the sunlight: “Damn, I am now certified!!!” That is my first thinking when I completed the first of the last two skills in dive no.4 – Mask fully removed, replaced and cleared!

I could never forget two worst moments when I wasn’t able clear my flooded mask. That led to lose my regulator and suddenly come up to the surface in scare. I couldn’t recall how many times I must practice clearing my mask at the pool – win then loose, on then off because the feeling of water in my eyes and my nose is the most irritating thing for me!

I always remember the first two dives I did with Sean Porter. He is the first instructor who saw my mask clear problem and also the last one to help me end it. He must be the most experienced, the most incredible instructor I’ve known ever!

The journey to become a certified Open Water diver takes so much time and effort of me and several instructors. Yes! Several ones!!! I have done 3 times of Discover Scuba Diving with 7 dives in total without being able to swim, spent 3 days at the swimming pool. For me, each dive at that time was exciting yet worrying. I brought with me excitement, joy, nerves to underwater every time.

I must say I used to hate breathing through regulator (the weirdest kind of air ever), I couldn’t get over the feeling of water under my nose (perhaps feeling only), I wasn’t be able to be calm every time I clear the mask (I did it too fast and improperly), I couldn’t kick fins correctly and balance myself underwater. On top of that, my heart beat ten times faster every time I descended! However those things only existed in me until yesterday 26 of April.

It was a lovely Friday at Racha Yai. There was no big wave, the water was as clear as its best visibility. Benoit and I were ready, excited to finish it. I told myself hundred times “Just do it and I can!”

Racha Yai Island

Tony- my instructor- always encouraged me and made me relaxed on the way to the islands while Sean and Claus kept teasing us. We went through briefing to make sure that we understood correctly what we were going to do underwater. Yeah! There is no difference from the pool except 6 meters deeper down the sea J . “You two watch me then repeat one by one” That’s what Tony always gave a sign before each skill. We took time to perform all the skills from easy to difficult. Fortunately, all went on slowly, gently and properly. After done with skills, we had fun dives – swimming around and look for some special stuff to see

I love Racha Yai because it is a new-diver-friendly dive site. We went from a sandy bottom to a hard corral pinnacle. Marine life down here is amazing! At the dive no.2 we immediately saw a moray eel. At first, it can remind of you the giant monster undersea with big long mouth and sharp teeth in the imaginary movies that we often see, in fact, it is not dangerous at all.

There are many blue sea stars laying on the ground, many ugly moving sea cucumbers, lots of groups of colourful fished that I don’t know their names… They all look amazing!

ImageAt dive no.3, we were so lucky to meet a group of barracuda. We got closer to them, watched them and stayed with them in a while. I really wanted to get into the group but afraid that they would swim away.

At dive no.4, Tony taught us to use the compass. It is quite important to master the navigation skill by compass. It helps us direct and avoids getting lost underwater. Once swimming on the surface with my compass, suddenly I forgot my buddy Benoit and swam too fast. Tony wasn’t happy about that and reminded us the importance of staying together with the buddy. Sean and Claus were watching and laughing a lot, yeah teasers again!

Once I finished CESA, I descended with Sean while Benoit and Tony were doing CESA. Few minutes later, I met Tony, Benoit and my lovely Thai colleague: Fon. I had prepared for this last dive, perhaps because of my uninteresting skill: Mask fully removal and replacement. After Tony’s demonstration, he came closer to me, hold my BCD and put his fingers on regulator. I knew he was always there in front of me. Taking a deep breath, I took the mask out, closed my eyes, pinch my nose for one second, slowly breathed out through my nose, put the mask strap over my head, pulled over and put on my face, taking a another deep breath, Breathing out through my nose, Opening my eyes, Seeing the sunlight, “Damn, I am now certified!!!” That was my first thinking. Looking at Tony, I saw his smiley eyes. He shakes my hand to congratulate me. I gave him a sign to show my happiness again. I swear it has been the happiest moment so far!

I felt all of the stress, worry and scare were released with the water once I finished it. I now could stabilize myself in the water by control my breath inhale and exhale, my fin kicking got better. There were moments I stretched myself out like a cat on the sofa. I turn myself around and enjoyed the feeling of being free.

As swimming around the pinnacle, we found a red octopus. It was my first time seeing it. Keeping our eyes on it in minutes, it suddenly swam away, we slightly moved after it, it went to a rock and changed its colour. What an amazing scene!

Not to bother it anymore, we continued our journey, on the way back I saw a lionfish. I have seen it few times and I couldn’t hold back to lionfish’s beauty. This lionfish noticed us so it opened its fin spines to warn us. How beautiful it is to see! But okay we would leave it alone.

Coming back to the boat, many people cherished me. I certainly couldn’t hide my happiness. On the way back to the pier, I was thinking of the efforts of so many peoples. What I have achieved today in dedication to Sean’s training, (Santa) Claus and Patrick’s experiences, Tony’s instruction, Debbie, Fon and Sang’s supports and many other’s encouragements.

Like most scuba divers, you were probably already fascinated with the beauty of both the scenery and marine life of the underwater world from the first dive. The next step is capturing this unique environment by taking some images with underwater photography. Whether you intend to take snapshots to show your friends and family, or create beautiful images of the world below by traveling to exotic destinations, you have to start somewhere.

At some point or another, most divers have thought about learning how to shoot underwater photography, many have taken the adventure dive as part of the advanced open water course. The affordability of digital cameras and the ability to instantly see the outcome of your efforts has reduced the barrier to trying and the learning curve to almost nothing. Add the ability to shoot video clips with even the most basic point & shoot cameras, and you can make scuba diving vacation memories to be the envy of your office and family.

There are many things to think about BEFORE picking up a camera.
Good buoyancy control is an essential skill not only for diving but for taking good photographs too. This needs to be mastered before adding the extra equipment and objective of taking a camera underwater. Taking the Peak Performance Buoyancy certification can do this.
Knowing the marine life you are going to photograph is a pretty big part of photography too, you need to be able to predict the movements and behaviour to get the best images. This can be studied in the underwater AWARE Fish ID and Naturalist specialties.
Obviously you will have new equipment with you, (the Camera) so a course, which teaches the use of this, is a good start point too, the Digital Underwater Photography course will cover this for you.

You may be a competent or experienced photographer on land but moving this experience underwater has a whole different set of issues to think about.

The first step to understanding any kind of photography is understanding your camera. If you have a new camera and housing, take the time to read the manuals. It may seem like a simple thing to do, but many people don’t.
As with any new diving equipment that you purchase, you should try out the photography equipment in a pool prior to diving, whenever possible. You will also want to take new camera housings underwater without the camera to ensure they are functioning properly. You don’t want to find problems with the housing while your camera is in it, this could lead to an expensive lesson.
No matter what camera you have, from an entry-level digital “point & shoot” to the most expensive dSLR , there are ten rules of underwater photography that should always be remember. Many of these rules are related to composition in the underwater environment and every photographer can benefit from proper composition.

1) Get Close, and when you think you are close enough, get closer again

Underwater photography differs from conventional wildlife photography, as it needs to be conducted up close. To get the best results you have to put as little water between your lens and the subject as possible.

The water holds small particles in it that reduce the contrast and sharpness of your image by dispersing light, this is called backscatter.

Water absorbs the light very quickly, and the most common complaint for new underwater photographers is the dull colours of their images.by getting closer and therefore removing the amount of water between the camera and the subject will mean a clearer, sharper, and more colorful image.

2) Shoot Up

Pointing the camera down as you take an image is often easier but will not result in the most interesting images.

Often the subject is lost in the background of reef as it is a more cluttered area. Pointing the camera more up can lead to clearer backgrounds and much more interesting images as you have contrast between the foreground and background.

3) Focus On The Eyes

A focused image is obviously important, but where you focus is too. Try to keep the eye of the subject in sharp focus, use this as the centre of the camera’s focal point.

4) Keeping Yourself Focused
Diving with a camera and diving without a camera are two totally different activities. After diving with a camera, you may find that those dives very different.
Patience is an extremely good quality to have when doing underwater photography, you may need to wait for divers to move out of the frame area, or for the subject to become used to you and start to behave in a more normal manor.

As a casual underwater photographer you dont need to be obsessive, but a level of personal focus and attention to detail will take your photography a long way.
Try to focus on a particular type of underwater photography, such as close-up or scenic and perfect your skills before moving on to the next type of shot. Avoid the shotgun approach of trying to capture everything that you see.

5) Use a Strobe

All divers know that water absorbs light, and therefore reduces the colour of the images you take, a strobe can be a way of restoring this.

Adding artificial light can give instant results to the photograph, but it is important to get the exposure right. Now most units come TTL ready and should give the correct light in all, but the most difficult conditions.

The photographer though has to ensure it is pointed in the right direction. Sounds simple, but if it is incorrectly positioned not only does it alter the quality of the image, but it also refracts the light so your subject appears closer and larger than it really is.

6) Shoot, Review, Adjust, Rinse, Repeat

Be patient, even though the digital photography gives us instant access to images, they still take time to perfect. The learning curve is shorterned by being able to see the image you have taken instantly on the screen. Take advantage of this by reviewing these images immediately after the photo has been taken, correct and re-take the image, adjust for composure, light, colour etc.

7) Go Manual
Starting off in auto mode is not a problem. But auto settings can only get you so far in underwater photography. To really control the exposure, colour and sharpness of your images you’ll need some degree of manual controls.

8) Maintain Your Equipment

Water and electronics don’t mix well so it is important to take your time when setting up your camera and housing. Make sure o-rings are clean and greased, but not over greased. A strand of hair or spec of dirt can be the difference between flooding your camera or using it. Always rinse your camera gear off with fresh water after every dive,never let salt water dry on your equipment.

While out on the dive boat be sure to keep camera gear out of the sun and away from heavy dive gear like scuba tanks and weight belts.

9) Respect the Environment

Remember, we are privileged guests in the underwater world, respecting the environment and marine life should be one of your top priorities. Before you start taking your camera underwater it is important to have excellent bouyancy skills, this will help protect both yourself and the environment around you. Keep all of your gear streamlined as to minimize the potential of a gauge or hose getting entangled or damaging the reef. Never harass or touch marine life. virtually everything you could touch is alive, touch it and it will damage it or even worse.
It can too often be seen the photographers who want a shot no matter what they have to break, kill or damage. It is important to stress to anyone who is keen to start underwater photography that as well as learning how to take a picture, you must also be environmentally aware.

If you have to damage anything to take a shot – don’t take it. Sometimes it is better to look and enjoy than try to take a photograph.

10) Have Fun

Don’t forget that underwater photography is supposed to be fun. Don’t get too caught up in the technical side. Start off with the basics, get a feel for it, and learn the technical side later.
Most of all, remember what you learned in your scuba diving class. You are a diver first and then a photographer. Your safety and that of divers around you depends on keeping this in mind at all times.

When diving over sand area’s of a dive site there are so many interesting critters that are often not seen or ignored by divers, one of these is the symbiotic pairing of the goby and shrimp.

Almost all of our dive sites by there nature have sandy bottoms and instead of passing quickly over them it is good to swim slowly and enjoy watching the behavior of these interesting room mates.
The sandy bottom of the reef is full of interesting creatures and fascinating methods have been devised for survival techniques used by reef inhabitants to prevent becoming food to predatory fish. Often this results in some interesting partnerships between marine creatures. One of the more curious relationships that most divers could have come across is that between the goby fish and the shrimp.
The little goby that firmly stands his ground outside his burrow belongs to a very special group of gobies called “shrimp gobies”. There are 70 or so brightly coloured shrimp gobies recorded worldwide in tropical waters and the western Indo Pacific is home to most of them. Their uniqueness is that they live in partnership with “pistol shrimps”. Pistol shrimps are so named for the loud snapping sound and the jet of water that comes from the rapid closing of a modified claw.

The gobies spend their day near entrance ways keeping their eyes peeled for predators, such as jacks and lizardfish, while the hard-working shrimp bulldoze sand into the open from the burrow below.
The front entrance of the burrow is often reinforced with bits of shell and coral put in place by the shrimp.

The goby will usually sit at the entrance of the burrow maintaining a constant vigil against potential predators, while the shrimp is clearing gravel from the burrow. Whenever the shrimp needs to dump gravel outside the burrow, it is usually exposed to potential predators. However with the Goby keeping lookout, the shrimp places one tentacle on the Goby while exposed, so if the Goby darts inside the burrow, the shrimp is instantly alerted of the presence of a predator and it too darts back inside the safety of its burrow. Often pairs of gobies or pistol shrimps will inhabit the same burrow.

They work between sunrise and sunset, resting with the gobies, inside the burrow at night. And like most homes, burrow construction varies according to its inhabitants. Scientists have even found that the sizes and shapes of burrows depend on the type of sediment available and to some degree on the species of shrimp. So the goby gets a professionally constructed and safe house away from predators, and somewhere to lay its eggs.
Gobies eat micro-fauna and sometimes tiny fish they find near the bottom, the shrimps feed on what they find in their burrowing and hence they do not compete for food.

The special relationship that exists between these two species is called symbiosis. Symbiosis literally means “living together” and can take more than one form but it is always between individuals of different species. It can mean, for example, that only one of the species benefits with no effect on the other, or that one species of the pair benefits but the other is harmed in the process. In the shrimp-goby case both species gain equal benefit and they significantly increase their chances of survival in a hostile world. This particular type of symbiosis is called “mutualism”. Their relationship is one that has developed through a mutual need and benefit to both species.

These animals are dependent on each other. Remove the fish, and the shrimp stops burrowing; the shrimp forage while burrowing, so without a fish, they grow more slowly. The shrimp need their guard goby, and the guard goby needs its shrimp: deny the goby shelter in a burrow, and it will promptly be killed by predators (someone did the experiment). The shrimp keep the goby clean, too: they groom it.

So how do the Gobies and Shrimp find each other in the first place? Shrimp-goby researchers have been trying to figure out this one for a long time, and have conducted numerous experiments to determine whether the Gobies find the shrimp, or vice versa, and also to determine whether they locate each other optically or are attracted chemically. There has been no definitive answer as to who spots who in this symbiotic relationship but it appears that the short sighted shrimp uses chemical senses, and the goby uses it’s much better developed visual sense for finding each other at a very young stage of their life.

Find out more about interactions and partnerships by taking the underwater Naturalist  specialty course with Scuba Cat and see the goby and shrimps at many of our dive sites both by daytrip and liveaboard.

The lionfish is a common site in the Andaman and seen on all of the dive sites we go to, both by daytrips and liveaboards.
Nobody knows for sure how they got their name, and they are also known as turkey or dragon fish in some area’s. One thought is when they spread out their pectoral fins it sort of looks like a lion’s mane, and they are ferocious predators

They are beautiful and fascinating fish but due to their colouring, as is common in nature, most times bright and beautiful means dangerous. Its bright colours advertise its poisonous tentacles. The venom of the lionfish, delivered by up to 18 needle-like dorsal fins and is purely defensive. A sting from a lionfish is extremely painful to humans and can cause nausea and breathing difficulties, but is rarely fatal.
The scientific name for the lionfish is Pterois, and there are fifteen different species in the Pterois Genus of fish.

The largest of the lionfish species can grow to about 40cm in length, but the average is closer to 30cm, with the smallest around 6cm, and they weigh somewhere around 500 to 900g. Their lifespan in the wild can be around 15 years.

They are mainly active during the day and at night the Lionfish find crevices among rocks that they rest in, this is so they are not out of the open where they would be at risk of predators consuming them.

It relies on camouflage and fast reflexes to capture their prey which is mainly fish and shrimp.. Adult lionfish use their distinct pectoral fins to attract the prey. As soon as the prey comes within their reach, they swallow it in a single motion. Though not quite unique, this method of hunting is highly successful in regions where the lionfish is a non-native species as the native population of the area is not used to such traps. They are able to move around very quickly in the water. They are very good at using those long pectoral fins to herd fish and other prey into a confined area, trapping it making it simple for them to get their food. The lionfish’s stomach can expand to 30 times its normal size so they can really fill up, this is why it is such an invader in the Caribean.

They are solitary and they will become very aggressive if they feel that their home territory is at risk. The males tend to be more aggressive overall than the females. While adult lionfish are solitary creatures, juveniles are known to live together in groups. Over the course of time, they become highly territorial and don’t even hesitate to take on the other members of their group to capture and/or defend their territory.

The native habitat of lionfish spans the rocky crevices and reefs of the Indo-Pacific waters, but they can be found in the eastern coast of America. It is not clear how they have found their way there but it is thought that some specimens who were released by certain aquariums, and have begun to thrive in these warm waters without any natural predators. There is one documented case of lionfish escaping from an aquarium located in a house damaged by Hurricane Andrew – the fish were seen swimming nearby after the storm. The “on purpose” introductions are assumed to occur from hobbyists who dumped them into canals (not knowing any better) when the fish either got too large for their aquariums or became unwanted. Genetic evidence from recent scientific results suggests multiple introductions.
