All sharks have compact bodies though few of these have wide fins in the end. So as with other fish species in addition they swim swiftly though they’ve bulky bodies.
Sharks teethes aren’t connected to the jaw but they’re suspended into the flesh of their mouth. This might be because they want more piercing power when attacking their prey. Interesting fact about sharks teethes is that in a typical, single shark may loose 30,000 teeth in a lifetime. Sharks have tails that provide them speed and acceleration. The arrangement of the tail varies from shark . Shape of the tail provides shark the capability to prey and survive in various environments.
Sharks respire through gill slits which are situated just next to head prior to the pectoral fin. In addition they have spiracle, a modified gill, right over the head though which they ingestion water when respiring. This spiracle plays significant role for the bottom dwelling sharks in which the oxygen concentration in the water is less. Sharks eyes are covered with a tissue called tapetum lucidum that made them ideal for marine atmosphere. Sharks life span might be from 20 to 30 years.
They could eat anything from small fishes, turtles, turtles, big fishes, and even other tiny sharks. They prey in groups if they’re preying on the surface of the water or in the bottom.
