The fin whale (Balaenoptera physalus), also known as the finback whale or common rorqual, is a species of baleen whale and the second-longest cetacean after the blue whale. The biggest individual reportedly measured 26 m (85 ft) in length, with a maximum recorded weight of 77 to 81 tonnes (85 to 89 short tons ; 76 to 80 long tons ).

Next to the blue whale, the fin whale is the second largest mammal in the world. They have a distinct ridge along their back behind the dorsal fin, which gives it the nickname "razorback.” Fin whales have a very unusual feature: the lower right jaw …

The Fin whale (Balaenoptera physalus) is a cetacean belonging to the parvorder of baleen whales. It is the second-longest species of cetacean on Earth after the Blue whale.

The Fin Whale (Balaenoptera physalus), also known as the finback whale or razorback whale, is the second-largest species of whale after the blue whale. This streamlined and elegant giant of the sea is known for its speed and has been nicknamed the “greyhound of the sea.”

With the invention and use of modern whaling technology, fin whale populations were depleted due to hunting. In addition, fin whales are injured or killed in vessel collisions. This is especially true in the Mediterranean Sea where collisions are a significant source of fin whale mortality.

Truly handsome individuals, fin whales have long, slender bodies that can grow up to a whopping 25 meters in length. With a distinct ridge running behind the dorsal fin, they have earned themselves the nickname “greyhound of the sea” and cut through the water with speed and ease.

Fin whales are the second largest animals in the world after the blue whale, the fastest swimming of the large whales, known as the greyhound of the seas, the commonest of the large baleen whales.

The fin whale is the commonest large whale in the eastern North Atlantic, Bay of Biscay and Mediterranean. Combining surveys encompassing shelf waters of northern Norway to those of southern Portugal yielded an overall estimate of around 18,000 fin whales in 2016, with the largest numbers in the Bay of Biscay.

Fin whales have a prominent, falcate (curved) dorsal fin located far back on their body. Their flippers are small and tapered, and their fluke is wide, pointed at the tips, and notched in the center. Like humpbacks , fin whales also communicate through vocalizations.

fin whales, like most balaenopterids, is a movement between poleward feeding areas in the summer months and lower latitudes in the winter months. Northern and Southern Hemisphere fin whale stocks are thought to be reproductively isolated from one another, as their migration schedules are 6 months out of phase.
