Le grand barracuda

By , 26 April, 2015, No Comment

Le Grand barracuda (Sphyraena barracuda) est le plus grand et le plus

impréssionant de son espèce pouvant mesurer jusqu’à 2 mètres et peser jusqu’à

50 kg. Le barracuda est facilement identifiable à sa forme tout en longueur, sa

coloration gris argentée et ses tâches noires caractéristiques diposées sur ses

flancs et la partie arrière de son corps. Avec une mâchoire inférieure de grande

taille, une large dentition forte et apparente ce poisson carnivore dégage un

aspect très agressif.

Le Grand barracuda vit dans les eaux tropicales de tous les océans. On le

rencontre dans les eaux de surface, il fréquente ainsi aussi bien la pleine mer que

les eaux sombres des ports. Solitaire à l’âge adulte, les jeunes barracudas

forment parfois de petits groupes afin d’améliorer leur chance de survie en

océan. Le grand barracuda adulte possède peu de prédateurs naturels. Les

jeunes, quant à eux, peuvent être victimes des thons géants et autres requins.

Avec une forme de torpille, le barracuda attaque ses proies de manière

fulgurante. Il peut ainsi atteindre une vitesse maximale de 45 Km/h. Il jongle

aisément entre les profondeurs en gonflant et dégonflant sa vessie natatoire tel

le gilet de flottabilité d’un plongeur. Ce prédateur diurne chasse à vue des petits

poissons, des calmars, pieuvres et autres crevettes.

D’un tempérament très curieux, il s’approche souvent des plongeurs et surtout

de leurs bulles.

Ici à Koh Tao vous aurez peut être la chance d’observer ces magnifiques

créatures lors de la plongée profonde de votre formation d’ Advanced ou de

plongées d’ exploration sur le site de Chumphon Pinnacle, l’un des sites de

plongée mythiques de Thaïlande. Pour en savoir plus sur nos formations ou nos

Puffer Fish

By , 23 April, 2015, No Comment

If you go to shallow dive sites around Koh Tao, such as Mango Bay and Twins, you will very likely see a puffer fish. The Puffer fish gets its name from its defensive response – puffing itself up to around two to three times its normal size when scared. They do this by sucking in huge amounts of water, which temporarily increases their size. The balloon-like sphere is created to protect the Puffer from unwelcome ‘guests’ by way of predators! They are not aggressive fish, and tend to be spotted during dives, for their comical swimming actions and large eyes that can move independently of each other. There are more than a hundred species of Puffer Fish, and many of them blend into to their surroundings by adapting their color and skin patterns.

Puffer Fish are mainly found in tropical areas, but there are some species that live in cool water environments – and rivers. Scuba divers generally categorize Puffers into two main types. The common Puffer which are kept in some aquariums and adorn popular dive locations around the world, and the Porcupine Fish (Puffer) –which has sharp spines that protrude upon inflating itself. Puffer Fish are considered by some to be a delicacy. However, caution should be exercised, as their flesh has toxins which can be harmful – lethal even – to humans.

The octopus

By , 22 April, 2015, No Comment

One of the strangest and most wonderful creatures in the ocean, credited as having a high level of intelligence but with limited memory and possibly the most versatile camouflage ability of any creature on the planet.

These creatures are fairly rare on Koh Tao but can be found on the odd occasion. Recent research from the Hebrew University of Jerusalem has recently figured out how they move across solid objects. Using high speed cameras they have concluded that the octopus simply chooses which leg to use and simply utilises it to pull or push it along.

As it has eight legs to choose from it can quickly move in any direction regardless of which way it is facing. This recent discovery is now being investigated to see if it can be applied to soft robotics, medical purposes and rescue operations.

Next time you’re diving watch out for these masters of disguise! If you want to know more you can always take your Project AWARE specialty.

The Sattakut

By , 21 April, 2015, No Comment

The HTMS (His Thai Majesty Ship) Sattakut has everything; history; eerie-ness; marine life in abundance; penetration points with natural daylight; penetration points with no natural daylight; depths up to 30 metres and correct punctuation from us here at Davy Jones Locker.

It was originally a landing craft infantry vessel commissioned by the US Navy in 1944, and was involved in three battles in World War II; the liberation of the Pilau Islands, the battle of Okinawa, and the battle of Iwo Jima.

In 1946 the US Navy decommissioned it, and it was purchase by the Royal Thai Navy. It lived out its service as a patrol boat, until they decommissioned it in 2011. Shortly thereafter, the Thai Department of Marine and Coastal Resources (DMCR) purchased the ship with the intention of donating it to Koh Tao to act as an artificial reef, in order to promote tourism. The vessel was stripped of it’s engines, furniture, electric cabling and thankfully it’s ammunition! After being cleaned and sent to Koh Tao, it was sunk on the 18th June 2011.

Unfortunately because a storm came in as it was being sunk, it ended up on its side in the middle of a channel; hardly an ideal location. So in July a salvage team was brought in to right the vessel and move it to a more suitable location.

It currently sits upright in around 30 metres of water, with the bow facing roughly North. The location is perfect, as it sits around 10 metres to the South of a dive site called Hin Pee Wee. This has obviously helped to bring marine life to the wreck, which is evident today- all over it! There is currently a huge Jenkins whip ray that lives underneath the hull. There are huge spotted snapper and giant groupers sheltering from the current near the conning tower, and if you have good eyes you will be able to find some Jan’s pipefish in the rusting railings. Moray eels also like to find places to sit and watch the underwater world go by. For those that want to venture inside, apart from disturbing a number of giant groupers from their hiding places, you will see lots and lots of shrimp.

The vessel is perfect for conducting technical training dives on which we provide here at Davy Jones Locker. There are many places on the main deck to practice reeling skills and teach communication in simulated no-visibility. Plus, there are numerous places to penetrate the wreck, and they vary greatly in terms of how quickly and how badly they silt out, so practising exits in zero visibility can be made progressively more challenging. The wreck is also a great place to conduct decompression procedures training dives, as there are plenty of reference points to use when ascending to meet run times, undertaking deep stops, and gas switching.

But it’s not all about training. Let’s not forget that this wreck has an amazing history, and sometimes it’s just great to go for a long deco fun dive around it, or a penetration fun dive inside it! The ship is the closest dive site to Davy Jones Locker on Sairee beach, and we use it a lot!

This month the diving conditions have again been amazing with 20m+ visibility and a massive variety of sea life. I had the recent pleasure of taking a group of open water students to twins dive site where we came across one of koh tao’s famous turtles, they all came up beaming and its safe to say they are now hooked to diving and have already completed their advanced.

The hawksbill’s appearance is similar to that of other marine turtles. In general it has a flattened body shape, a protective carapace, and flipper – like arms, adapted for swimming in the open ocean. E. imbricata is easily distinguished from other sea turtles by its sharp, curving beak  with prominent tomium, and the saw-like appearance of its shell margins.

Hawksbill shells slightly change colors, depending on water temperature. While this turtle lives part of its life in the open ocean, it spends more time in shallow lagoons and coral reefs.
