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 marine animals such as seals are capable of hydrodynamic reception, enabling them to track and catch prey such as fish by sensing the disturbances their passage leaves behind in the water. [36] Marine mammals such as dolphins, [ 37 ] and many species of bat, [ 6 ] are capable of echolocation , which they use both for detecting prey and for ...
Electroreceptive animals use the sense to locate objects around them. This is important in ecological niches where the animal cannot depend on vision: for example in caves, in murky water, and at night. Electrolocation can be passive, sensing electric fields such as those generated by the muscle movements of buried prey, or active, the ...
Estimates of Wilson's Phalarope numbers are several thousand, and the birds can be seen in areas of water both large and small. You might get dizzy just watching!" These birds create whirlpools by ...
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.
Frogfishes capture their prey by suddenly opening their jaws, with a mechanism which enlarges the volume of the mouth cavity up to 12-fold and pulls the prey (crustaceans, molluscs and other whole fishes) into the mouth along with water; the jaws close without reducing the volume of the mouth cavity. The attack can be as fast as 6 milliseconds.
Birds of prey are able to drop down on unsuspecting snakes and snatch them up into the air in a split second! Watch this exciting video to learn which animals possess the skills needed to ...
Touch: All fish have a lateral line along the middle of their body that can discern vibrations in water. "Sharks can detect both the direction and amount of movement made by prey, even from as far ...
