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 ...
The colossal squid is thought to have a very slow metabolic rate, needing only around 30 grams (1 oz) of prey daily for an adult with a mass of 500 kilograms (1,100 lb). [38] Estimates of its energy requirements suggest it is a slow-moving ambush predator, using its large eyes primarily for prey-detection rather than engaging in active hunting.
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.
The arid land surrounding Lake Turkana is a relatively barren region for diverse or numerous prey other than fish, so fish are an exceptionally important food source to crocodiles there. [ 5 ] [ 10 ] > In Lake Kyoga and Lake Kwana , 73.1% of the crocodiles that did not have empty stomachs had fish in their stomachs. [ 11 ]
A zoo has been giving its animals warm meals and drinks to help them through the cold weather. Jodie Bryant, head of primates at Dudley Zoo and Castle, said: "The main thing is we're providing ...
In nocturnal predators non-visual clues are especially important. The barn owl (Tyto alba) relies on noises made by prey, and can locate prey animals with great precision. Bats have the added capability of echolocation to locate prey like flying insects; they can therefore locate prey even if they make no sound. [4]
More broadly, the researchers argue, tracking wildlife is important in understanding the unpredictable ways animals adapt to that changing planet — and a vital tool for ecology in the future ...
Most research on the detection of surface waves has been done on the striped panchax, Aplocheilus lineatus. Surface wave detection by animals is the process by which animals, such as surface-feeding fish are able to sense and localize prey and other objects on the surface of a body of water by analyzing features of the ripples generated by objects' movement at the surface.
