September is go!
chumphon-sidemountTrue to form, September is looking good so far on Koh Tao. The sea is flat calm, the weather is scorching hot, and the underwater visibility is absolutely breathtaking! Every dive site is just incredible to dive at the moment. At Chumphon pinnacle yesterday you could see the bottom from the boat, and when diving the pinnacle you could see way way off into the distance; even the thermocline at 40 metres seems to have gone on holiday! I dived the HTMS Sattakut a few days ago- our very own purposefully sunk artificial reef, and again you could see practically the entire vessel from the surface, all 48 metres of it, which is unheard of!
There is a huge array of marine life all over the place too, in the last month we've seen whalesharks, a pod of pilot whales and false killer whales, and on the macro scale the Bruce Lee of the ocean: the mantis shrimp.
September is always a great time to visit, but this is the best one in years! It's a little quieter than usual too, probably because people have been put off visiting Thailand due to the coup. Yet it hasn't affected anything, there is no curfew, no army presence on Koh Tao (and barely any visible signs in Bangkok either). Life continues as it always has- great diving, Sun, sea, lounging on the beach, and a huge choice of amazing food to choose from. Bet you're annoyed you went to Blackpool instead now aren't you....

Mantis Shrimp facts
These little critters are amazing in every conceivable way, so here's a few facts to show you why:

- They can grow up to 11cm long.
- They're very brightly colored. Their shells can be blue, green, red and orange. The forearms are often covered with spots.
- Their eyes are located on long stalks that move independently. They have exceptional eyesight that is used both for the detection of prey and predators.
- Their eyes are also the most complex in the animal kingdom. They can see ultraviolet and polarized light. They have trinocular vision which means that they can see objects using one of the three different parts of eye.
- All mantis shrimps can be divided on spearers and smashes, based on the morphology of appendages and tactic they use to kill the prey.
- Spearers have spiny appendages that are used to stab soft-bodied prey such as different types of worms and fish.
- Smashers have club-like appendages that easily smash shell of snails, oysters, crustaceans and molluscs.
- They attack their prey extremely quickly- 50 times faster than the blink of an eye. With a velocity of 10 meters per second, their punch has the power of a .22 calibre bullet.
- Smashers are famous for their incredibly strong punches that can break the glass of an aquarium!
- Most species of mantis shrimps are solitary and territorial creatures. They fiercely defend their home against intruders.
- They are able to recognize their neighbours by smell, and also by their shape.
- Some species of mantis shrimp are monogamous and spend up to 20 years together. During mating, they often fluoresce.
- Females can lay eggs in the burrows or keep them in their forelimbs until they hatch. Some species exhibit parental care. The female lays two sets of eggs, one for her and the other for the father to take care of the eggs until they hatch.
- Larvae of mantis shrimps swim as a part of zooplankton up to 3 months. They show aggressive behaviour even during the larval stage.
- Mantis shrimp can survive more than 20 years in the wild.
