jagged shark teeth

The morphology of shark teeth varies depending on the prey they eat. In addition to the jagged `` sawtooth '' that bites large prey, sharks with plate-shaped teeth that crush hard things such as sea urchins and crabs and sharks that eat plankton as a staple food have teeth smaller than grains of rice.

ticking shark eggshell

Shark friends mate with females using clasps (copulatory organs) in which part of the male's ventral fin has changed, and perform internal fertilization. There are also oviparous sharks, which produce fertilized eggs, and viviparous sharks, which hatch from the eggs in the belly of the mother shark and are born in the same shape as their parents.

rough shark skin

The true nature of the rough shark skin is the scales called "junrin", which grow from the head side to the tail fin side, so it feels rough to the touch. These rough scales reduce frictional resistance when swimming.
