What is commonly called a pit organ allows these animals to essentially "see" [1] radiant heat at wavelengths between 5 and 30 μm. The more advanced infrared sense of pit vipers allows these animals to strike prey accurately even in the absence of light, and detect warm objects from several meters away.
For instance, snakes have TRPA1 in their pit organ which is an ion channel that works as the infrared receptor controlling the flux of calcium ions. This type of receptor gives snakes the ability to detect infrared light and this ability is often called "heat vision". [15]
The result is an inward calcium and sodium current similar to capsaicin-evoked currents. TRPV1 channels may also have voltage-sensitive properties responsible for its activation. [13] Phosphorylation and mutations, especially at the C-terminus (carboxylic acid end of primary amino acid sequence), can alter the threshold temperature of heat ...
Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .

Underwater hearing is by bone conduction, and localization of sound appears to depend on differences in amplitude detected by bone conduction. [7] As such, aquatic animals such as fish have a more specialized hearing apparatus that is effective underwater. [8] Fish can sense sound through their lateral lines and their otoliths (ears).

Cats have one of the broadest ranges of hearing among mammals. [11] Humans and cats have a similar range of hearing on the low end of the scale, but cats can hear much higher-pitched sounds, up to 64 kHz, which is 1.6 octaves above the range of a human, and 1 octave above the range of a dog.
