It is Hot Hot Hot right now and the diving is lovely, a couple of Whalesharks have been hanging around lately so everyone is out on our early boats to try and catch a glimpse of the gentle giant.

Many of you travellers are now trying to squeeze as much into your holiday in a short space of time. For those of you who only come to Koh Tao for a night or two we offer a one day try dive, this is not a certification but a taster of what diving is all about. With a maximum of 2 people per instructor we guide you around one of our shallow dive sites, with the option of completing a second additional dive. If after this day you are hooked (which most people are) change your travel plans and stick around for a few more days a get your full Open Water Diver certificate. With nearly all currencies being particularly strong right now it is the best time to come over and get your licence. All of our courses start every single day so no need to worry about availability.

Everybody has their own favourite fish to see and one of the most popular on Koh Tao is the Little Yellow Boxfish. The yellow boxfish AKA Ostracion cubicus, can be found in reefs throughout the Pacific Ocean and Indian Ocean as well as the south eastern Atlantic Ocean. It has been known to reach a maximum length of 45 centimetres (18 in). As the name suggests, it is box-shaped, with tiny little dorsal fins and puckering pink lips. When they are juveniles, it is bright yellow in colour with blue spots. As it becomes older, the brightness fades and on very old specimens the colouration becomes blue as the spots get larger. The fish's diet consists of marine algae, worms, crustaceans and small fish.

Interestingly as a defensive mechanism when stressed or injured it releases an extremely poisonous protein from its skin that proves lethal to any fish in the surrounding waters.

In 2006, Mercedes-Benz unveiled its Bionic concept car, which was inspired by the shape of the yellow boxfish. It was assumed that due to the extreme agility with which boxfish can manoeuvre, that their shape was aerodynamic and self stabilizing. However, if you have ever seen one try and swim you may think this is a rather stupid idea and funnily enough when an analysis by scientists was performed they actually found that the boxfishes agility is instead due to the combination of an aerodynamically unstable body and the manner in which the fish use their fins for movement. Good job Mercedes, maybe you should have done your research first!
