The average length of sexually mature female blue whales is 22.0 meters (72.1 ft) for Eastern North Pacific blue whales, 24 meters (79 ft) for central and western North Pacific blue whales, 21–24 meters (68–78 ft) for North Atlantic blue whales, 25.4–26.3 meters (83.4–86.3 ft) for Antarctic blue whales, 23.5 meters (77.1 ft) for Chilean ...
Whales are fully aquatic, open-ocean animals: they can feed, mate, give birth, suckle and raise their young at sea. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the
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).
Mosasaurus hoffmanni was the largest squamate lizard to have ever lived, with a length of 11 meters (36 ft) and a body mass of 10 metric tons (11 short tons) [90] However, the largest reptiles, period, were the shastasaurids, specifically Ichthyotitan, which approached lengths rivalling to exceeding those of a blue whale, at around 26–35 m ...
Female sperm whales are physically mature at about 10.6 to 11 meters (35 to 36 ft) in length and generally do not achieve lengths greater than 12 metres (39 ft). [35] [37] [39] The largest female sperm whale measured up to 12.3 meters (40 ft) long, and an individual of such size would have weighed about 17 tonnes (19 short tons).
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.
The largest measured individual was a lactating female 12.65 meters (41.5 ft) in length; USNM 594665 is the largest known male of the species and is 11.26 meters (36.9 ft) long. Adults may be as small as 7 meters (23 ft) in length, and many verified and possible Rice's whales do not exceed 10 meters (33 ft).
Before 4.5 million years ago, few baleen whales exceeded 10 meters (33 ft) in length; the two largest Miocene species were less than 13 m (43 ft) in length. [44] The initial evolution of baleen and filter feeding long preceded the evolution of gigantic body size, [ 45 ] indicating the evolution of novel feeding mechanisms did not cause the ...
