They range from the small harbor porpoise found in shallow coastal waters to massive sperm whales diving below 1000 meters to catch the perfect squid! Canada has made it illegal to catch and hold whales, dolphins and porpoises in captivity. A positive correlation between association patterns and kinship has been previously reported in cetaceans (e.g. In this study, we evaluated tissue toxicant concentrations and pathology data from 83 odontocetes that stranded in the southeastern United States during 2012–2018. Whales and dolphins are iconic species that hold a special significance for many users of the Great Barrier Reef.
