The baleen whales, also called whalebone whales, form the Mysticeti, one of the two suborders of the Cetacea ( whales dolphins and porpoises). Baleen whales are usually larger than toothed whales, females being bigger than males.   This group includes the largest animal species, the blue whale.  The baleen whale has two blowholes, causing a V shaped blow.

Despite their enormous size they have the ability to jump fully above the surface. One whale that is known for their water feats is the humpback whale.  Baleen whales can grow to larger than 110 feet long, and can weigh up to 420,000 pounds.

Baleen whales have baleen, a straight, stiff material that hangs from the roof of their upper jaw. It is made of keratin, (the same substance that your fingernails and hair is made of). The inside of baleen have little hairy plates, that help filter krill, plankton, and small fish.

The Fin whale is an fairly endangered animal. They are very large whales, and the ones that live in the northern hemisphere can be around 60 feet. The ones in the southern hemisphere tend to reach closer to 70 feet. It is the same for males and females. Fin whales can be found in all the major oceans, with water temps polar and tropical. Though the Fin whale can live in different temperatures, they are found more commonly in colder climates. The only known predator of the Fin Whale is the killer whale, and even so, there are not many sightings of attacks. The Fin Whale is a baleen whale, and it eats only small fish, squid and other little crustaceans. The gestation period for a calf is 11-12 months.

Fun fact: fin whales can live up to 140 years!

The gray whale is a baleen whale and so it feeds mainly on krill and other very small crustaceans. the grey whale also lives in pods of 3-16 whales but they form groups of hundreds of whales when in feeding groups. The grey whale lives mainly on the coast from Alaska down to Mexico and that is their migration route too. Their gestation period is about 13 months and a newborn calf weighs as much as 1.8 tons. Grey whales have a life expectancy of about 50-60 years and  they are a protected species. Grey whales grow  to be 45-50 feet in length at the most, females are slightly larger than females though. The grey whale also can grow to be 36 tonnes! Overall the grey whale is an amazing and beautiful animal.
