here u go

Explanation:

The only fish that can keep their body temperature higher than the surrounding water are tuna, opah, and mackerel sharks. The tuna is an active and agile predator with a sleek, streamlined body and is one of the fastest-swimming pelagic fish – the yellowfin tuna, for example, can reach speeds of up to 75 km/h (47 mph). However, greatly exaggerated speeds can be found in early scientific reports and are still commonly reported in popular literature.  Formal paraphrase It is found in warm seas and is heavily fished commercially. It is also popular as a game fish. Some tuna species, such as the southern bluefin tuna, are threatened with extinction as a result of overfishing. While squid are cephalopods in the Decapodiformes superorder with elongated bodies, large eyes, eight arms, and two tentacles. The squid, like all other cephalopods, has a distinct head, bilateral symmetry, and a mantle. They are mostly soft-bodied, like octopuses, but have a small internal skeleton made of chitin in the shape of a rod-like gladius or pen.
