After exposure to the 1989 Exxon Valdez oil spill, two male resident killer whales experienced dorsal fin collapse, and the animals subsequently died. In 2002, the dorsal fin of a stranded killer whale showed signs of collapse after three days but regained its natural upright appearance as soon as the orca resumed strong normal swimming upon ...
Pygmy killer whales also have rounded-tipped dorsal fins, as opposed to pointed tips. When compared to false killer whales, pygmy killer whales have a larger dorsal fin. Finally, pygmy killer whales have a more clearly defined line where the dark dorsal color changes to the lighter lateral color than either of the other two species. [9]

Dorsal fin of a shark. A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom.Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments ...
Old Thom is a large bull orca, and is estimated to be 25 to 30 feet (7.6 to 9.1 m) long, with an estimated weight of 8 short tons (7.3 t). [3] The whale is identified by a distinct notch a third of the way down the posterior side of the dorsal fin.
