Trying new things

By , 12 November, 2014, No Comment

I’ve been teaching diving on Koh Tao for over two years now and I’ve logged over 800 dives.  I love showing new people the beauty of the underwater world for the first time.   That’s really the thrill in being an instructor for me.  Surely there’s not too much more for me to do or learn here on Tao in terms of diving, right?

Actually, nothing could be further from the truth!  I recently did the TDI extended range course with our tech instructors, Dave and Ollie.  We went down to deeper than I’ve done before and I learned a ton about dive planning, gas management and safety drills.  It was like being an open water student again because the equipment and procedures are all so different.  It really pushed my boundaries and I had a great tipeterubiksme doing it.

I also tried to set the world record for deepest Rubik’s Cube solve under water at 45 meters.  It was a solid attempt, but I failed…  :(    Next time!

Nudibranchs

By , 14 October, 2014, No Comment

Koh Tao has many different types of fish and marine life, one of which is the nudibranch.

Nudibranchs (pronounced Noo-di-BRANKs) are gastropod mollusks. That’s a fancy way of saying ‘sea slug.’ Unlike other slugs, nudibranchs possess fantastic coloration and colour patterns. The coloration of each species comes from the prey they eat: the more colourful the prey, the more colourful the nudibranch. There are more than 3,000 species of nudibranch worldwide and more species are being discovered all the time. They crawl slowly across the ocean floor using a single foot, just like a garden snail. Some types of nudibranchs live only a month, while other species live as long as a year. Some species are only about one-quarter inch long at full maturity, others can swell to as long as 12 inches. Nudibranchs have many strange protrusions, including a pair of horn-like tentacles or “rhinophores” worn near the front of their bodies. These horns are primarily chemical sensing organs that help the nudibranch find its prey. Nudibranchs have soft bodies and most lack an external protective shell. This exposure is what inspired their neo-latin/greek name “nudibranch” which means “nude or naked gills.”Without a shell, nudibranchs had to evolve another way to ward off predators. They accomplished this in multiple ways: the development of toxic (aka bad tasting) glands in their skin, and bright colours meant to tell predators that taking a bite is a terrible decision. But that’s not all. Aeolid nudibranchs steal nematocysts (stingers) from the animals it eats (corals, sea anemonesand jelly fish).

HTMS Sattakut

By , 26 September, 2014, No Comment

Hey all,

 

today I’m going to be talking about one of the great wrecks we can dive to on this island, the HTMS Sattakut. The Sattakut was laid down at Commercial Ironworks in Portland Oregon. She was launched on February 27th, 1944 and commissioned into the US Navy as a Landing Craft Infantry large. After her long service she was commissioned into the Thai Navy as the HTMS Sattakut in 1946, and was sunk in Koh Tao on the 18th of June 2011 and to this day she is one of the most popular sites to dive especially for a PADI advanced open water course.

She lies approximately 40m south of Hin Peewee with her bow facing Northwest, Sitting upright. The top of the wreck is around 20m and and since she lies on a slope the bottom is at about 32m. When she was sank as a part of an artificial reef project in 2011 she landed on her starboard side in a different location to where she is now, it was only after a few months that her position was corrected and she was put back upright that more and more people started to dive on her.

Dive Island

By , 24 September, 2014, No Comment

People come to Koh Tao for various reasons, whether for the night life and  parties or our beautiful beaches and bays, but you can’t overlook the diving!

Koh Tao is a scuba diving island, it’s the reason everything is here today and the undoubted highlight of the gulf of Thailand so why not consider it. I’ve been diving here for 3 years with Djl diving growing from a complete beginner to a teaching instructor and along the way I’ve seen some amazing things… From eagle rays at Japanese Gardens, turtles at Twins and White Rock, a WWII era ship wreck just off hin pee wee, and everyone’s favorite giant, the whale shark out at Chumphon, South West or Green Rock, along with all the countless other fish that inhabit our wonderful reefs.

It’s all down there just waiting to be explored!!!

Sea Cucumber

By , 20 September, 2014, No Comment

One of the joys of diving is learning about the thousands of different underwater creatures that live in our oceans.  Students always ask me about the fish they see when we surface.

One of the animals that I get the most questions about is the sea cucumber.  They’re are wild looking bunch of creatures that look like thick, short worms.  Here’s some interesting facts about them:

  • Their body consists of collagen fibers that they can loosen and tighten at will.  So if they want to squeeze into a crack in the rocks, they can essentially liquefy their body and then tighten back up once the emerge.
  • There are over 1,700 different species of sea cucumber which can look wildly different from one another.  Some of them have feet and can walk around (we see these here) and some of them have webbed structures that allow them to effectively swim around.
  • We see lots of them on dives here on Koh Tao, but they also are very common at extremely deep depths (kilometers under water) where they make up to 90% of all the animals that live so deep.
  • They’re certainly not the most beautiful animals we see, but they’re cool in their own way.
