For example, Upper Oligocene sediments of Baja California Sur yield a diversity of baleen-bearing mysticetes
(Barnes, 1998, 1999, 2002), and lowermost Miocene sediments in Baja California Sur have yielded baleen-bearing mysticetes
of moderate size (Gonzalez-Barba et al.
The humpback whale (Megaptera novaeangliae), fin whale (Balaenoptera physalus), and southern right whale (Eubalaena australis) are other examples of mysticetes
Unlike other arctic mysticetes
, bowheads float when they are killed, and so can be recovered and flensed immediately as long as the animal does not escape under ice.
Paleontologists have long thought that Mysticetes
and Odontocetes represent separate evolutionary lines that split from a group of ancestral toothed whales some 40 million years ago.
01) and Mysticetes
had a higher mean prevalence of the barnacle than Odontocetes (5.
1%) were reported in 2,000 mysticetes
(baleen whales) hunted in South Africa (19).
Scientists have long thought that Blues and other baleen whales, which belong to a suborder called Mysticetes
, evolved millions of years ago from ancestral toothed whales, but they have lacked detailed fossil evidence to chronicle the transition from teeth to baleen.
In later years, especially in the North Pacific, when the number of baleen whales caught represented a small proportion of the total catch (relative to sperm whales, the primary target) these occasional mysticetes
would be processed together with sperm whales for bone-meal and industrial oil.
Gray whales are unique among mysticetes
in that they suction sediment and benthic organisms (e.
