fin whaleor finback whale or razorback whale or common rorqualSwift, slender-bodied baleen whale (Balaenoptera physalus) named for the ridge on its back. It is 59–89 ft (18–27 m) long, with a triangular dorsal fin, short baleen, and several dozen grooves along its throat and chest. It is gray, with white on the underparts and on the right side of the lower jaw. It is found in oceans worldwide, in groups of a few to several hundred. It lives in polar waters in summer, feeding on crustaceans and small fishes, and moves to warmer waters in winter to breed. Once commercially valuable, it has been substantially reduced in numbers by overhunting and is now listed as an endangered species. How to thank TFD for its existence?

Finally, a trip to the Cape wouldn't be complete without watching the whales, most commonly humpbacks but also large finbacks, smallish minkes and even endangered right whales (which are not approachable). Osborn and his crew knew they would be intercepted once Chinese radar identified them and the Chinese would send up a pair of J-8 Finback fighters to check out the EP-3E. Payne knew that finback whales communicate by infrasound, sounds pitched so low (less than 20 hertz, or 20 sound cycles per second) that humans feel the physical vibration like pounding bass music rather than hear the sound. |
