Autotomy serves either to improve the chances of escape or to reduce further damage occurring to the remainder of the animal such as the spread of a chemical toxin after being stung, but the 'decision' to shed a limb or part of a body and the considerable costs incurred by this suggests a pain response rather than simply a nociceptive reflex.
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]

The idea that animals might not experience pain or suffering as humans do traces back at least to the 17th-century French philosopher, René Descartes, who argued that animals lack consciousness. [ 14 ] [ 15 ] [ 16 ] Researchers remained unsure into the 1980s as to whether animals experience pain, and veterinarians trained in the U.S. before ...
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 ]
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 ...
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 ...
Lizards have evolved several modes of communication, including visual, chemical, tactile, and vocal. [9] [2] Chemical and visual communication are widespread, with visual communication being the most well-studied, while tactile and vocal communication have traditionally been thought to occur in just a handful of lizard species; however, modern scientific techniques have allowed for greater ...
