North Andaman Liveaboard –  Similans, Koh Bon, Koh Tachai  and Richilieu Rock MV Scuba Adventure departed from Patong on the evening of the 4^th en-route to the Similans. Kath, the Tour Leader and Steve, the Dive Master welcomed on board Lucrezia and Rene from Switzerland, Mats from Sweden, Guido and Gianna from  Italy and Peter and Karen from England. With the boat briefing completed, cabins allocated, equipment set up we had a relaxing dinner where everyone became acquainted.

We woke to the beautiful scenery of Island 5 and 6, which is the home of Anita’s Reef. With the dive safety and dive sight briefing done we kitted up for our first dive of the trip. Anita’s reef did not disappoint. The stunning coral bommie was covered in glass fish, which was a sight to be seen. Nudibranch, Fusiliers, Snappers were all out in their glory. The pristine white sand was home to the dancing Garden Eels and Khuls rays.  A banded pipe fish was found on one of the large boulders on the corner of Island 5.  After breakfast we headed to Island 9 and North Point. This site is a combination of huge rock formations and reef. It is briefed as “but one get one free!!”  The rocky formation has several swim throughs together with coral gardens nestled between the rocks.   Turtles were in abundance as they poised for the photographers in the group. The turtles here are not at all shy and continued munching away as if to say”Oh they’re only divers!”   We also saw a banded sea snake head to the surface for air. In the shallows a rock formation was covered in Purple Dragon Nudibranch. A treat for the macro lovers on the boat.

After lunch we arrived at Koh Bon for our 3^rd dive of the day. We were fortunate as we were the only divers in the water at this popular sight. We dropped in on the corner and made our way to the West Ridge. A large school of yellow snapper were below us as we reached the ridge. On the ridge there were hunting Long Nosed Emporers, Trevelly and Rainbow Runners.  A Devil Scorpion was camouflaged amongst the broken coral on the reef.  A meter away was an octopus hiding in a rock. There was so much to see!!! The glass fish again, were food for the larger hunters…a feeding frenzy. A Mantis Shrimp quickly ran across the reef, which was a first for some of the divers.

A highlight of the dive was to see 2 Napolean Wrasse swimming around us for a while.  The divers who chose to do the night dive on Koh Tachai Reef saw many different types of crabs, shrimps and spent about 10 minutes with a free swimming moray, which hunted successfully catching an unsuspecting fish for dinner!!

Day 2 and the Captain started the engines at 3.40am. We were on our way to Richelieu Rock. Here we did 3 dives. The Rock is worthy of multiple dives as the marine life here is so prolific. A school of giant barracuda were waiting our arrival! Fortunately, we were able to locate a sea horse and 2 ornate ghost pipe fish.  Cuttle fish were in abundance as they displayed their courtship ritual. The whole area was like being in fish soup with large schools of fish swimming around us. Cleaner pipe fish were found in the crevices, mantis shrimps along the bottom hiding and a devil scorpion camouflaging itself as a piece of coral. Needless to say there were many more creatures too numerous to mention. One highlight was seeing a zebra moray free swimming in the shallows.

The 4^th dive of the day was a sunset dive at Jetski Rock on Koh Tachai. A chilled out relaxing dive. The trevellies were in menacing hunting mode as they circled the glassfish on the reef. They are truly the “Gangsters” of the reef. A moray was enjoying being cleaned by a cleaner shrimp as the surrounding marine life prepared for bed. The sunset when we surfaced was spectacular and gave the perfect ending to a great day. Day 3 started with the morning dive on Koh Tachai Pinnacle. With a slight current it was easy navigate around the site.  The corals on the pinnacle are beautiful. Soft corals, gorgonion sea fans, whip coral are abundant.  A few barracuda were hanging above the site and the resident bat fish were between two huge boulders. Rene and Lucrezia were lucky and saw a leopard shark. They did have photographic evidence, so we had to believe them!!

The second and third dives were on Koh Bon. Hunters were menacing as they circled amongst the glass fish and then without warning a feeding frenzy. The third devil scorpion fish of the trip was also seen. However, the icing on the cake at Koh Bon was the manta on dive 2. We were in the shallows coming towards the end of the dive when the manta appeared. This amazing creature brought smiles to all our faces as it approached us several times. Dive 4 was a sunset dive in the Similans and on West of Eden on Island 7. This dive was relaxing as we slowly worked our way along the reef swimming between the coral blocks. Glass fish in abundance, feather stars in every colour and an array of fish. Day 4 and an early start on Elephant Head Rock and boy oh boy did it pay off…..As soon as we dropped in we had a white tip reef shark laying on the bottom at 20m. As we approached it swam away. However, several minutes later we saw two side by side. Elephant Head has some lovely swim throughs and one of the white tips swam into it. Kath was the only diver to see this. The huge granite boulders with the coral gardens between are very impressive. The second dive on Shark Fin Reef was an easy dive for the end of the trip. Shark Fin reef has dramatic scenery of huge granite boulders. In one of the long cracks in a rock there resting was a Jenkins Ray. Further along the reef we saw a large school of giant barracudas. This was the first trip of the season to the Similans and Richelieu Rock and if this trip was anything to go by then we should have a wonderful season.

Octopuses are the master of disguise on a reef. Many times someone may be pointing at apparently nothing and then as with a 3D photo and octopus appears!!!! This remarkable creature is compelling watching as it changes colour and texture. Camouflage is possible due to specialized skin cells that can change colour, opacity and reflectiveness of the epidermis. It is believed that the colour changing is a means of communicating with others and also to warn of danger. The muscles in the skin enables the octopus to alter the texture of it’s mantle so as to blend in with it’s surroundings, for example, the bumpy texture of a rock. There is also evidence to suggest that octopus living on a complex habitat such as a reef and are more active during the day have a more developed skin than the sand dwelling and nocturnal partners.

There are 300 recognised species of octopus worldwide. All are known to be venonmous, but only the blue ringed octopus is deadly to humans. Octopuses have 4 pairs of arms and 2 eyes and are bilaterally symmetric. There is no internal or external skeleton, which enables the creature to squeeze through small spaces if fleeing from predators. They are regarded as the most flexible and intelligent of all invertebrates having both having long and short term memory.  There is only one hard part of the body, this being the beak, or mouth that is found at the centre point of the arms.

Octopuses have very good eye sight and some species are able to distinguish colour. They are also able to distinguish the orientation of their body to the horizontal using two organs that are attached to the brain called statocysts. There is also an automatic reponse that keeps the eyes orientated, so that the pupil slit is always horizontal.

The sense of touch is excellent and the suction cups found on the arms have numerous chemoreceptors that enable the octopus to taste what it touches. The arms also show a variety of complex reflex actions. This is due to 2/3 of the neurons of the complex nervous system being located there. The arms also have tension receptors, so the octopus can determine if the arms are stretched out, but the receptors are not sufficient for the brain to determine the actual position of them.

This creature also has three hearts, two are branchial hearts that pump blood to each of the two gills and the third pumps blood through the body.  The blood contains a copper rich protein called hemocyanin, which is effective for transporting oxygen in cold conditions and environments where there is low oxygen pressure. The protein is dissolved in the plasma and gives the blood a bluish colour.

The life expectancy of the octopus is short from 6 months to 5 years. The death of the octopus is genetically programmed and results after reproduction. The male of the species may live for a few months after mating, but the female will die shortly after the eggs are hatched.  During reproduction the male will insert a specialised arm called a hectcotylus into the female’s mantle where it deposits spematophore (packets of sperm). Some species can keep the sperm alive inside the female for a few weeks until the eggs are mature. Once fertilization occurs the female will lay her eggs, which she hangs in strings from her lair or individually on the substrate. This varies depending on the species.  A female may lay upto 200,000 eggs. The incubation period is approximately a month. During this time she is the protector and will gently blows a current of water across the eggs providing them with enough oxygen. However, it is to her detriment as she will not hunt. It has been known for the female to ingest one or more of her arms for sustenance.  Once the eggs are hatched she will leave being very weak and defenseless thus dying.  The larval octopus will drift for a while in clouds of plankton where they feed. . Plankton eaters such as mantas and whale sharks are obviously a threat to the larvae. When they are ready they will descend to the ocean floor.

Octopuses move by crawling on their arms or by swimming. They swim in a horizontal position with the arms behind. Movement is by expelling a jet of water from a contractile mantle. This is one of the primary defense mechanisms as they are capable of fleeing at great speed. Another form of defense is the use of thick blackish ink, melanin, which is dispersed in a cloud. It is believed that the ink reduces the olfactory organs of some hunters that hunt by smell, for example, sharks. It is also known that an octopus is capable of detaching an arm as a distraction when under attack.  The mimic octopus is highly flexible and is able to change shape to look like other creatures. It has the capability of changing to look like a more dangerous creature than the one that is attacking.

These remarkable sea creatures are worthy of watching while on a dive. If you are lucky enough to see one then do not get too close as the octopus will hide in crevices and cracks in the substrate. It is better to observe from a distance away and slightly elevated. Be patient and wait motionless. The octopus will eventually gain confidence and gradually come out into the open for you to enjoy the moment!!!!

If you would like to know more about the identification of species why not sign up for on a  Underwater Naturalist Specialty Course, which will enhance your knowledge and highlight the key things to look for, or a cruise on board MV Scuba Adventure or MV Scuba Fun for a chance to see these for yourself.

Life is never dull here at Scuba Cat Diving, 5 * CDC Phuket, Thailand.

The Hard Rock Cafe was celebrating its first anniversary of being open here in Phuket and came to see us to see if we would be involved…………….. Some of the instructors threatened me with Death if I dared say no………….

They were to Host “Miss Hard Rock -Phuket”!

Miss Hard Rock Cafe Phuket 2010

and strangely enough the male instructors on the team were queuing up to take the Beautiful Thai Girls for one of their first round challenges…………..

Try Dives and a Beach Clean up in Patong.

Claus and Darren were two of the first Volunteers to take the Hot Thai Girls on their first Scuba Diving experience and Matt Butcher, Scuba Cat’s own professional videographer recorded the Dayalong with many helpers, including our Instructor Interns!

The Gorgeous girls all had a great day,

……….However it was the first time we have had to clean the pool after try dives to prevent the filters being blocked by false eye lashes, earrings…………….

So after reapplying their makeup, and redoing their hair……… the Thai Girls went over to Patong Beach to Clean up ……………… I have never seen the trash get cleared up so quickly as it did by these skimpily dressed Thai Girls!!!!

A big Thank you to Andrea who completed his internship with us during 2010. He completed all his courses with Scuba Cat Diving from Open Water to IDC Staff Instructor.

“It has been a superb journey from doing my OW in 2009 to my OWSI in 2010. I’ve worked with many international and corporate teams in my career but nothing comes close to what I have experienced at Scuba Cat Diving. A dedicated, trained and professional team. They are to share my every bit of success today. Scuba Cat Diving is obviously a good training ground for any future instructors. Congratulations on an excellent course. I look forward to my continued education in your program, heading to MSDT and there after IDC Staff.”
