Fin Whale or Finback Whale or Common Rorqual * Vinwalvis * Balaenoptera Physalus

It can be found in both polar and tropical seas in all the major oceans.

The fin whale was widely hunted during the 20th century, just like all other great whales. It is therefore a threatened species. Between 1905 and 1976, it is estimated that about 725,000 fin whales were hunted from the Southern Hemisphere; as of 1997, only 38,000 remained.

Adult males and females are roughly 18.5 and 20 meters (61 and 66 feet) in length and weigh an average of 38.5 and 50.5 tonnes, respectively.

Male whales emit low-frequency, lengthy, loud sounds like other whale species do. The lowest-frequency noises produced by any animal are the vocalizations of blue and fin whales.

The killer whale is the only known predator of the fin whale. A fin whale was killed at the Canal de Ballenas, Gulf of California, in October 2005 after being pursued for almost an hour by 16 killer whales. Before departing the location, they fed on its sinking body for roughly fifteen minutes.

The animal can swallow up to 70 cubic meters (18,000 US gal; 15,000 imp gal) of water in one gulp when it opens its jaws while swimming at about 11 km/h (6.8 mph). It then closes its jaws and forces the water through its baleen (their filter system), allowing the water to escape while leaving their prey behind.

In order to gather krill, the whale regularly dives to depths of more than 200 m (660 ft), doing an average of four "lunges" every dive. The whale consumes about 10 kg (22 lb) of food with each gulp. Every day, a whale can eat up to 1,800 kg (4,000 lb) of food.

The majority of fatalities are caused by collisions with ships. They contribute significantly to the stranding of big whales in various regions. The majority of fatalities are brought on by large, swift ships over or close to continental shelves.
