Sea Sharks And Dinosaur
370 species of the sea sharks have been recognized so far. Study reveals that the sea sharks were in existence even 400 million years ago but got extinct with the extermination of approximately 96% living creatures of the earth. Sea sharks are compared with an exceptional and extraordinary earth creature Dinosaur which also had extincted hundreds of years ago. The remarkable fact about the sea shark is its re emerging again in the ocean against the pre historical creature Dinosaur which still is a fictitious creature for the adults and children who come to know about this monstrous creature, that is Dinosaur, only through movies and comics.
There are different species of sea Sharks recognized as a viviparous and oviparous marine creature, for out of recognized species, many sharks lay their eggs while many of them give birth to pups only. Viviparous female shark lays its eggs in a litter of its womb, where at least 5 to 25 pups get developed with the eggs getting hatched there and come out of female shark's body after the completion of required gestation period varying varying from12 to 25 months.
While the oviparous sharks lay their eggs in the ground of sea water which hatch on their own under the required sea teperature. Average time to be consumed by the eggs in getting hatched is 100 to 136 days in period depending upon the temperature of the oceanic water.
Another exceptional thing about the shark is that they mate only one or two times in a couple of years and produce not more than 25/30 pups at a time.
