Basking Shark
Cetorhinus maximus
Living individuals or members of this group exist today. This does not mean they are safe from extinction.
The basking shark is a very large fish that gathers small plankton rather than chasing large prey. Its open mouth and almost encircling gill slits create a distinctive outline near the surface.

Habitat and range
Basking sharks occur widely in temperate seas and make seasonal movements. They use coastal shelf waters as well as offshore areas, following changing feeding opportunities.
Appearance and adaptations
A conical snout, enormous mouth and long gill slits distinguish the species. Fine structures on the gill arches trap plankton as water passes through. The body is generally greyish or brownish above.
Diet and behaviour
The shark swims through concentrations of zooplankton with its mouth open. Food distribution influences its movements. Despite its size and slow surface feeding, it is also capable of leaping clear of the water.
