Diving with whale sharks
Get up close at the Andaman sea
The whale shark is found in open waters of the tropical oceans and is rarely found in water below 22 °C (72 °F). Modeling suggests a lifespan of about 70 years, but measurements have proven difficult. Whale sharks have very large mouths and are filter feeders, which is a feeding mode that occurs in only two other sharks, the megamouth shark and the basking shark. They feed almost exclusively on plankton and therefore, are completely harmless to humans.
Two frog fishes at the Similan islands
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.
