Whales, the ocean’s largest marine mammals, renowned for their immense size and exceptional adaptability can be found roaming waters all over the world. From the depths of the Arctic to warm ...
Modern baleen whales, Balaenopteridae (rorquals and humpback whale, Megaptera novaengliae), Balaenidae (right whales), Eschrichtiidae (gray whale, Eschrictius robustus), and Neobalaenidae (pygmy right whale, Caperea marginata) all have derived characteristics presently unknown in any cetothere and vice versa (such as a sagittal crest [42]). [43]
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
A researcher fires a biopsy dart at an orca.The dart will remove a small piece of the whale's skin and bounce harmlessly off the animal. Cetology (from Greek κῆτος, kētos, "whale"; and -λογία, -logia) or whalelore (also known as whaleology) is the branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoises in the scientific ...
Thus, more recent evolution of these complex blubber traits occurred after baleen whales and toothed whales split, and only in the toothed whale lineage. [ 10 ] [ 11 ] [ 12 ] Modern toothed whales do not rely on their sense of sight, but rather on their sonar to hunt prey.
That is, the names are not capitalised except for the first word of a sentence and any proper names that are part of the common name. An example of the general use is bowhead whale. Examples of the inclusion of a proper name are North Pacific right whale (where "North Pacific" is a placename) and Bryde's whale (where Bryde was a person's name).
Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance. [2]
The whale's scientific name is Eubalaena glacialis, which means "good, or true, whale of the ice". The cladogram is a tool for visualizing and comparing the evolutionary relationships between taxa. The point where a node branches off is analogous to an evolutionary branching – the diagram can be read left-to-right, much like a timeline.
