The Basking sharks (lat. Cetorhinus maximus) can be found in the waters of the Atlantic and Pacific Oceans. They prefer to stay alone or in small groups at depths of up to 1000 meters. Basking sharks are the second-largest fish on the planet after whale sharks. They can grow up to 10 meters long and weigh 4 tonnes. These sharks have a massive grey-brown body, a conical snout, a huge mouth and very large gills.
