The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, it is found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
Other predators are crocodiles, wolves and dogs, large raptors, and for small species and young animals, large snakes. For cetaceans, possible predators include sharks, polar bears, and other cetaceans; in the latter is the orca, the top predator of the oceans.
Orcas or killer whales have a cosmopolitan distribution and several distinct populations or types have been documented or suggested. Three to five types of orcas may be distinct enough to be considered different races , [ 1 ] subspecies , or possibly even species [ 2 ] (see species problem ).
The duo is well-known among the study’s authors and has been involved in hunting and killing great white sharks for many years. The orcas’ dorsal fins are bent in opposite directions — the ...
Blue whale Humpback whale A pod of narwhals Beluga Atlantic white-sided dolphin Orcas. The infraorder Cetacea includes whales, dolphins and porpoises. They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion ...
Feb. 28—Elk in northeastern Washington have a lot to deal with. Beyond the basic needs of food and water, the animals have to manage a complex network of competing predatory threats — from ...
Keep a safe distance: Give animals their space. The National Park Service’s requirements are a good rule of thumb — 25 yards from most wildlife and 100 yards from predators like bears and wolves.
The horns of female bovids are thought to have evolved for defense against predators or to express territoriality, as nonterritorial females, which are able to use crypsis for predator defense, often lack horns. [60] Rhinoceros horns, unlike those of other horned mammals, consist only of keratin.
