About the location and site

Elephant Head Rock alias Hin Pusa lies 1.5 km located in open water to the south of Similan Island 8 (Koh Similan). It is the biggest and probably the second most-recognizable pinnacle in the Similans.  There are three large boulders that emerge above water, with the biggest one located in the west. The Surface rocks look like a bathing elephant when approached from the west, hence the name. The huge boulders that form Elephant Head Rock create a maze of swim-troughs, sheer walls, arches, caverns, gullies and tunnels – great places for marine life to hide, and great places for divers to discover! 
The dive site at Elephant Head Rock is surrounded by sand at a maximum depth of 35-40 meters. Being so exposed it offers excellent visibility in its deep waters. You do need to be careful of your decompression time.Many divers find Elephant Head the best deep boulder dive of the Similan Islands chain.

​Frogfishes are any member of the anglerfish family Antennariidae. Frogfishes are found in almost all tropical and subtropical oceans and seas around the world, the primary exception being the Mediterranean Sea.
Frogfishes are small, short and stocky, and sometimes covered in spinules and other appendages to aid in camouflage. The camouflage aids in protection from predators and to enables them to lure pray. Many species can change colour; some are covered with other organisms such as algea or hydroza. In keeping with this camouflage, frogfishes typically move slowly, lying in wait for prey, and then striking extremely rapidly, in as little as 6 milliseconds.

This group includes some of the most colourful creatures on earth. In the course of their evolution, nudibranchs have lost their shell while developing alternative defence mechanisms. Some species evolved an external anatomy with textures and colours that mimicked surrounding sessile invertebrate animals (often their prey sponges or soft corals) to avoid predators. Other nudibranchs, as seen especially well on chromodorids, have an intensely bright and contrasting colour pattern that makes them especially conspicuous in their surroundings. ​

The puffer's unique and distinctive natural defenses help compensate for its slow locomotion. It moves by combining pectoral,dorsal,anal and caudal fins. This makes it highly maneuverable, but very slow, and therefore a comparatively easy predation target. Its tail fin is mainly used as a rudder, but it can be used for a sudden evasive burst of speed that shows none of the care and precision of its usual movements. The puffer's excellent eyesight, combined with this speed burst, is the first and most important defense against predators.

Its backup defense mechanism, used if successfully pursued, is to fill its extremely elastic stomach with water (or air when outside the water) until it is much larger and almost spherical in shape. Even if they are not visible when the puffer is not inflated, all puffers have pointed spines, so a hungry predator may suddenly find itself facing an unpalatable, pointy ball rather than a slow, tasty fish. Predators which do not heed this warning (or which are "lucky" enough to catch the puffer suddenly, before or during inflation) may die from choking, and predators that do manage to swallow the puffer may find their stomachs full of tetrodotoxin, making puffers an unpleasant, possibly lethal, choice of prey. This neurotoxin is found primarily in the ovaries and liver, although smaller amounts exist in the intestines and skin, as well as trace amounts in muscle. It does not always have a lethal effect on large predators, such as sharks, but it can kill humans.

Jelly fish are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey.
Jellyfish are found in every ocean, from the surface to the deep sea. Scyphozoans are exclusively marine, but some hydfrozoans live in freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. Jellyfish have roamed the seas for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal.
