Overview

Archive Note

The whale shark is a cartilaginous, filter-feeding shark rather than a whale. It takes in seawater and strains plankton, fish eggs and small organisms using specialized filtering structures.

Distinctive pale spots and stripes cover its back, with individual patterns useful for identification. It inhabits tropical and warm seas, ranging from offshore waters to coastal feeding sites.

Whale sharks grow and mature slowly. Estimates of their maximum size differ depending on measurement and observation methods, so this record does not treat the proposed upper length as an exact measured specimen.
