The humpback whale (Megaptera novaeangliae) is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the only species in the genus Megaptera. Adults range in length from 14–17 m (46–56 ft) and weigh up to 40 metric tons (44 short tons).
The blue whale (Balaenoptera musculus) is a marine mammal and a baleen whale.Reaching a maximum confirmed length of 29.9 m (98 ft) and weighing up to 199 t (196 long tons; 219 short tons), it is the largest animal known ever to have existed.
The gray whale (Eschrichtius robustus), [1] also known as the grey whale, [5] is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of 14.9 meters (49 ft), a weight of up to 41 tonnes (90,000 lb) and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age.
It can constitute as much as 50% of a whale's body weight. Calves are born with only a thin layer of blubber, but some species compensate for this with thick lanugos. [40] [41] Whales have a two- to three-chambered stomach that is similar in structure to those of terrestrial carnivores.
Ranging from 9 to 98 feet in length, whales are the largest creatures on Earth.Scientists believe the first whales evolved over 50 million years ago, according to the University of California ...
The largest confirmed weight of a giant octopus is 74 kg (163 lb), [244] with a 7 m (23 ft) arm span (with the tentacles fully extended) and a head-to-tentacle-tip length of 3.9 m (13 ft). [245] Specimens have been reported up to 125 kg (276 lb) but are unverified. A weight of 10 - 50kg is a much more common size. [1]
An adult whale usually measures 14 to 18 m (46 to 59 ft) in length and 75 to 100 t (74 to 98 long tons; 83 to 110 short tons) in weight. The fluke of this species measures 2–6 m (6 ft 7 in – 19 ft 8 in) long and the 230 to 360 baleen plates are thought to grow to 4 m (13 ft) long, which is longer than that of any other whale by more than a ...
Between 40% and 50% of their body weight is fat, which is a higher proportion than for cetaceans that do not inhabit the Arctic, where fat only represents 30% of body weight. [ 39 ] [ 40 ] The fat forms a layer that covers all of the body except the head, and it can be up to 15 cm (5.9 in) thick.
