Gray's beaked whale (Mesoplodon grayi), sometimes known as Haast's beaked whale, the scamperdown whale, or the southern beaked whale, is one of the better-known members of the genus Mesoplodon. This species is fairly gregarious and strands relatively frequently for a beaked whale. In the Māori language, this species is called hakurā or iheihe ...
Round scars from cookiecutter shark bites can be seen on the flank of this stranded Gray's beaked whale. Mesoplodont beaked whales are small whales, 3.9 m (13 ft) (pygmy beaked whale) to 6.2 m (20 ft) (strap-toothed whale) in length, [3] even compared with closely related whales such as the bottlenose whales and giant beaked whales. The spindle ...
To understand the hunting and foraging behavior of beaked whales, researchers used sound and orientation recording devices on two species: Cuvier's beaked whale (Ziphius cavirostris) and Blainville's beaked whale (Mesoplodon densirostris). These whales hunt by echolocation in deep water (where the majority of their prey is located) between ...
Drone video of gray whales captured over seven years off Oregon has revealed new details about how the giant marine mammals find and eat food. Among the findings, described in two studies ...
Eschrichtiidae or the gray whales is a family of baleen whale (Parvorder Mysticeti) with a single extant species, the gray whale (Eschrichtius robustus), as well as four described fossil genera: Archaeschrichtius (), Glaucobalaena and Eschrichtioides from Italy, [1] [2] and Gricetoides from the Pliocene of North Carolina.

A minke whale's annual diet consists of 10 kilograms of fish per kilogram of body mass, [53] which puts a heavy predatory pressure on commercial species of fish, thus whalers say that an annual cull of whales is needed in order for adequate amounts of fish to be available for humans. Anti-whaling campaigners say that the pro-whaling argument is ...
The gray whale (Eschrichtius robustus) is a species of whale related to the rorqual whales [25] that has been eradicated from the Atlantic by fishing, and now survives only in the North Pacific. [17] Nevertheless, adventurous or stray individuals occasionally reach the Atlantic Ocean, and some have been observed as far south as the ...
The gray whale population experienced an unusual mortality event from 2019 to 2023, which scientists believe was caused by a decrease in available prey in the northern Arctic seas, resulting in a ...
