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.
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 ...
In experimental settings, animals have demonstrated perceptual switching: visual predator would form a searching image of the most abundant cryptic prey species in their environment; as the species is more predated, its number would decrease and the search image for that species would be less useful to the predator; the predator would then ...
The High-Tech Tools Scientists Use to Track Wild Animals Science in recent years has seen an explosion of wildlife tracking-devices that are enabling new insights and scientific breakthroughs.
A recent video uploaded by the U.S. Fish and Wildlife Service shows a group of spinning Wilson's Phalaropes in Quivira National Wildlife Refuge, Kansas. The USFWS post notes, "there is a lot of ...
Individuals that want to track marine wildlife in salt water face unique challenges. Radio waves are highly absorbed by salt water, making them a poor choice for sending messages through the ocean. Sound waves, on the other hand, are not similarly impeded by seawater. Due to the fact that sound can travel more than 4 times faster in water than ...
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.
"A small-spotted genet visits a water pond for a sip and glimpses a cluster of small carp swimming below the water’s surface. These elusive creatures are adept hunters of various prey: fish ...
