The sensory function of vibrissae is an active research area—experiments to establish the capabilities of whiskers use a variety of techniques, including temporary deprivation either of the whisker sense or of other senses. Animals can be deprived of their whisker sense for a period of weeks by whisker trimming (they soon grow back), or for ...
The sense is mainly used for orientation and navigation, but it may help some animals to form regional maps. Experiments on migratory birds provide evidence that they make use of a cryptochrome protein in the eye, relying on the quantum radical pair mechanism to perceive magnetic fields.
Although they have ears, many fish may not hear very well. Most fish have sensitive receptors that form the lateral line system, which detects gentle currents and vibrations, and senses the motion of nearby fish and prey. [1] Sharks can sense frequencies in the range of 25 to 50 Hz through their lateral line. [2]
This helps cats gauge whether they can fit through tight spaces, detect prey, and even sense vibrations in the air, giving them the ultimate “sixth sense” when it comes to navigating the world ...
They appear to rely on their leg and shoulder bones to transmit the signals to the middle ear. When detecting seismic signals, the animals lean forward and put more weight on their larger front feet; this is known as the "freezing behaviour". Elephants possess several adaptations suited for seismic communication.
Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. [ 1 ] [ 2 ] Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate . [ 2 ]
Kiwis, sandpipers and ibises have Herbst corpuscles on their bill tips, allowing them to sense vibrations. [1] They are named after the German embryologist Curt Alfred Herbst. In many wading birds, a large number of Herbst corpuscles are found embedded in pits on the mandible that are believed to enable birds to sense prey under wet sand or ...
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. [ 1 ] Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the ...
