Fish use a variety of low poached sound to
convey message each other. They moan gnash their teeth. However, fish do not
have vocal chords. They use other parts of their bodies to make noises, such as
vibrating muscles against their bladder.
Fish can form schools containing millions of
fish. They use hold their place in the school. The lateral line is a raw of
pores running along the fish sides from head to tail. Special hairs in the
pores sense changes in water pressure from the movement of other fish or
predators. Since a fish jaw, is not attached to its skull, many fishes can
shoot their mouths forward like a spring to catch stared prey.
Fish have sleep like periods where they have
lowered response to stimuli, slowed physical activity and reduced metabolism
but they do not share the same changes in brain waves as human being do when
they sleep.
Some fish such as herbivore often lack jaw
teeth but have tooth like grinding mills in their throat called pharyngeal
teeth most fish have taste buds all over their body. Most fish can in color and
use colors to camouflage themselves or defend themselves and their territory.
Most fish have the best possible eyesight for their habitat and can most certainly
see you peering in a fish pond.
A fish does not add new scales as it grows,
but the scale it has increase in size. In this way, growth rings are formed and
the ring reveal the age of a fish.
Fish that have thin fins with a split tail
indicate that they move very quickly or many need them to cover great
distances. On the other hand fish that live among rocks and reefs near the
ocean floor have broad lateral fin and large tails.
A fish can draw in water like human, fish
need oxygen so if there isn’t enough oxygen in the water they will suffocate. The
fish in the middle of a school controls the school. The fish on the outside are
guided by those in the middle. Only bony fish can swim in highly coordinated
groups.
Fish would suffocate if they try to chew
because chewing would interfere with water passing over their gills.
