Goosebumps also regulate body temperature, by trapping a layer of air close to the skin. ... Animals get goosebumps, too. The same phenomenon helps some animals look bigger, in response to ...

Goosebumps have a practical purpose for animals. When an animals’ hair sticks up it makes it look bigger and helps protect it against predators. A raised layer of fur can also help keep an ...
Vasomotor responses allow control of the flow of blood between the periphery and the core to control heat loss from the surface of the body. Lastly, the organism can show insulation adjustments; a common example being "goosebumps" in humans where hair follicles are raised by pilomotor muscles, also shown in animals' pelage and plumage.

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.
