Size of the southern right whale compared to an average human Balaenids are large whales, with an average adult length of 15 to 17 metres (45–50 feet), and weighing 50-80 tonnes. Their principle distinguishing feature is their narrow, arched, upper jaw, which gives the animals a deeply curved jawline.
They are classified in the family Balaenidae with the bowhead whale. Right whales have rotund bodies with arching rostrums, V-shaped blowholes and dark gray or black skin. The most distinguishing feature of a right whale is the rough patches of skin on its head, which appear white due to parasitism by whale lice. Right whales are typically 13 ...
The bowhead whale is among the largest baleen whale species and is distinguished by its round body with an exceptionally curved rostrum, a large head, and long, dark baleen plates. Relative to its size, the bowhead whale has the largest head of any cetacean, [11] measuring nearly 40% of the total body length. [12]
The closely related bowhead whale differs from the right whale by lacking any callosities, having a more arched jaw and longer baleen. The seasonal ranges of the two species do not overlap. The bowhead whale is found at the edge of the pack ice in more Arctic waters in the Chukchi Sea and Beaufort Sea, and occurs in the Bering Sea only during ...
The skim-feeders are right whales, gray whales, pygmy right whales, and sei whales (which also lunge feed). To feed, skim-feeders swim with an open mouth, filling it with water and prey. Prey must occur in sufficient numbers to trigger the whale's interest, be within a certain size range so that the baleen plates can filter it, and be slow ...
New estimate for endangered right whale population in 2023 shows a slight increase, but scientists fear it could be temporary after a deadly 2024
A size comparison of a whale shark and a human. The cartilaginous fish are not directly related to the "bony fish," but are sometimes lumped together for simplicity in description. The largest living cartilaginous fish, of the order Orectolobiformes, is the whale shark (Rhincodon typus), of the world's tropical oceans.
English: Size comparison of a tiger shark and a human being (rough approximation, as tiger sharks vary considerably in length). Čeština: Srovnání velikosti člověka a žraloka tygřího. Jde jen o orientační náčrt, neboť velikost jednotlivých žraloků se může značně lišit.
