Fish Physiology Notes -

This is a series of fluid-filled canals containing mechanoreceptors called neuromasts . It allows fish to detect vibrations, pressure changes, and the movement of predators or prey nearby.

: As water enters through the mouth and passes over the gill filaments, dissolved oxygen is absorbed into capillaries while carbon dioxide is released. Counter-Current Exchange Fish Physiology Notes

. This field covers vital processes like respiration, circulation, osmoregulation, and sensory perception, which are all specifically adapted for underwater life. 1. Respiration and Gas Exchange Unlike terrestrial vertebrates that use lungs, fish rely on for gas exchange. This is a series of fluid-filled canals containing
