How to identify Whale shark

Whale sharks are the largest fish on earth and are striking with their massive, broad bodies. Their grey-blue skin is covered with a unique pattern of white spots and vertical stripes. The head and mouth are exceptionally wide and flattened at the front.

The pectoral fins are powerful and the dorsal fin tapers gently. Another distinguishing feature is the small eyes on the sides of the head. While juveniles often show more contrasting patterns, these fade slightly in adult whale sharks.
