As water is a much better electrical conductor than air, electrocommunication is only observed in aquatic animals. There are various animals that can detect electrical signals, but fish are the only aquatic animals that can both send and receive EOD, making them the only animals to effectively communicate using electrical signals.
An electric fish generates an electric field using an electric organ, modified from muscles in its tail. The field is called weak if it is only enough to detect prey, and strong if it is powerful enough to stun or kill. The field may be in brief pulses, as in the elephantfishes, or a continuous wave, as in the knifefishes.
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 ...
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.
Forage fish, also called prey fish or bait fish, are small pelagic fish that feed on planktons (i.e. planktivores) and other small aquatic organisms (e.g. krill). They are in turn preyed upon by various predators including larger fish, seabirds and marine mammals , this making them keystone species in their aquatic ecosystems .
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.
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 ...
The archerfish (also known as spinner fish or archer fish) or Toxotidae are a monotypic family (although some include a second genus) of perciform tropical fish known for their unique predation technique of "shooting down" land-based insects and other small prey with jets of water spit from their specialized mouths.
