Animal navigation is the ability of many animals to find their way accurately without maps or instruments. Birds such as the Arctic tern , insects such as the monarch butterfly and fish such as the salmon regularly migrate thousands of miles to and from their breeding grounds, [ 1 ] and many other species navigate effectively over shorter ...
Arthropods like these northern prawn, and some mammals, detect water movement with sensory hairs such as whiskers, bristles or antennae. In animal physiology, hydrodynamic reception refers to the ability of some animals to sense water movements generated by biotic (conspecifics, predators, or prey) or abiotic sources.
Many prey animals, and to defend against seed predation also seeds of plants, [55] make use of poisonous chemicals for self-defence. [51] [56] These may be concentrated in surface structures such as spines or glands, giving an attacker a taste of the chemicals before it actually bites or swallows the prey animal: many toxins are bitter-tasting ...
Pagophilic animals, plants, etc. prefer to live in ice or perform certain activities in the ice. For example, a number of ice seals are described as pagophilic as they have adapted to breed and feed in association with their ice habitat. The preference for a frozen habitat has been observed in several mammalian, avian and invertebrate species.
Many prey animals systematically migrate between refuges and predator-rich feeding grounds, in patterns that minimize their chances of being caught by the predators. The largest such migration by biomass is the oceans' diel vertical migration , in which vast quantities of organisms hide in the lightless depths of the open ocean, arising after ...
"Recent examples include the monitoring of arctic temperatures and vegetation changes during climate change and documenting ocean currents, and in the future may allow for the estimation of ...
The attraction of huge numbers of prey fish means that these predator species, which might otherwise be mutually antagonistic, usually cooperate with each other in pursuit of their common goal. Bryde's whales often track dolphin groups as they herd prey species. As soon as the dolphins corral the prey, the whales lunge feed through the centre ...
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. [ 5 ] It is found in all major animal groups, including birds , [ 6 ] mammals , [ 7 ] fish , [ 8 ] [ 9 ] reptiles , [ 10 ] amphibians, insects , [ 11 ] and crustaceans .
