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.
Tracking in hunting and ecology is the science and art of observing animal tracks and other signs, with the goal of gaining understanding of the landscape and the animal being tracked (the "quarry"). A further goal of tracking is the deeper understanding of the systems and patterns that make up the environment surrounding and incorporating the ...
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 ...
No matter what the form of pollution is, the effects water pollution has on animal life can be drastic. For example, the BP oil spill which occurred in 2010 impacted over 82,000 birds, 6,000 sea turtles, approximately 26,000 marine animals, and hundreds of thousands of fish. [27]
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.
Grouping may swamp the predator's capacity to capture prey - for example, hawks are unable to capture more than one yellow-eyed junco per attack. [5] Large groups also cause predator confusion as it makes it difficult for prey to focus on one target. [1] Groups of animals may engage in communal defences, such as mobbing, for further protection. [1]
Humans are some of the best long distance runners in the animal kingdom; [6] some hunter gatherer tribes practice this form of hunting into the modern era. [7] [8] [9] Homo sapiens have the proportionally longest legs of all known human species, [3] [10] [11] but all members of genus Homo have cursorial (limbs adapted for running) adaptions not seen in more arboreal hominids such as ...
