Basking Shark - Cetorhinus maximus
Photo by

Basking sharks can attain lengths of up to 45 feet and are one of the largest fish in the world with only some whale sharks being larger. They have a grayish-brown to completely grey or black spindle-shaped body that can reach up to 45 feet long. Basking sharks have very long gill slits, tiny rows of teeth, and large combs of horny gill rakers that they use to filter plankton at a rate of 2,000 tons of water per hour. They often break the surface with their broad dorsal fin and have even been known to jump out of the water.
