Whale sharks are the largest fish in the world. The species is believed to grow up to 18 -20 m, but rarely find specimens measuring 12 m in weight with 20 tonnes. Despite its size, whale sharks tend to be benign and harmless to humans.

This shark has a gray 2 mm thick leather and is decorated with white totol. According to scientists, the totol-totol pattern is considered unique for each individual and can be used as a basis for the identification of individual whale sharks.

Tropical and subtropical waters are warm (18-30 C) except in the Mediterranian Sea can be found presence of whale sharks. This fish is a migratory animal.

It is suspected that individuals whale sharks encountered in Ningaloo Reef, Australia migrate to the Philippines through Indonesia.

In Indonesia, whale sharks are found in the waters of Sabang, West Kalimantan, Berau, Situbondo, Probolinggo, Bali, Nusa Tenggara, Alor, Flores, North Sulawesi, Maluku and Papua.
