  Range of the salmon shark

The salmon shark (Lamna ditropis) is a species of mackerel shark found in the northern Pacific ocean. Similar to other mackerel sharks, salmon sharks have a thunniform body type. As an apex predator, the salmon shark feeds on salmon, squid, sablefish, sea otters, birds, walleye pollock, and herring.[3] Salmon sharks get their name from their diet, which primarily consists of salmon. It is known for its ability to maintain stomach temperature (homeothermy),[4] which is unusual among fish. This shark has not been demonstrated to maintain a constant body temperature. It is also known for an unexplained variability in the sex ratio between eastern and western populations in the northern Pacific.[5]
