Now I will talk to you about the some senses sharks have that you might have never known existed.
Firstly,
sound, the ears of the sharks are interesting for they are very
sensitive to
high frequency, their ears are small pores at the summit of their
heads, they
have also an internal ears in their cranial area, that is just a small
organ
that looks like a bag. Their ears for example can hear an anchor
dropping more
than 1km away.
Secondly
sharks have electrolocation that are in the nose, they are small tubes
filled
by the a geletin like liquid they are called the Bulbs of Lorenzini
they can
detect the low level electricity emitted by the fishes around the
sharks, the
Hammerhead shark one more bulb to help find the fish in the sand and
help stay
out of danger.
And
finally how do the sharks breathe? Easy
they have the gills, in a more complicated way water enters the mouth,
the gills
take the oxygen from the water, carbon dioxide exits the branchial
slits. Most
sharks always have to swim so that the water can enter their mouth and
continue
pumping oxygen through the sharks body.
