How Many Sharks Species Are There – Different Types of sharks

Types of sharks – Species and their characteristics

Spread throughout the seas and oceans of the planet, their area unit quite 350 species of sharks, though it’s not in any respect comparable to the quite one,000 fossil species that we all know. Prehistoric sharks appeared on planet Earth four hundred million years past, since then several species have disappeared et al have survived the good changes that the world has undergone. Sharks as we all know them these days appeared a hundred million years past.

The existing style of shapes and sizes implies that sharks are classified into numerous teams and among these teams, we discover dozens of species. we have a tendency to invite you to understand, during this AnimalWised article, what percentage kinds of sharks their area unit, their characteristics, and several other examples.

Despite being the biggest shark in its cluster (almost 2 meters long), the species is critically vulnerable because of intensive fishing. they’re aplacental viviparous animals.

In the northwest and west-central Pacific, we discover another species of monkfish, the marking shark (Squatina Tergocellatoides). little is thought concerning this species as there are unit few cataloged specimens. Some information indicates that they continue to exist the bed at depths between a hundred and three hundred meters since in trawling they’re typically caught accidentally.

Laminiform sharks have 2 dorsal fins and one anal fin. they are doing not have nictitating eyelids, they need 5 gill slits and spiracles. The enteric valve is formed sort of a ring. Most have Associate in Nursing elongated snout and also the gap of the mouth reaches behind the eyes.

The strange hob shark (Mitsukurina owstoni) contains a international however uneven distribution, they’re not distributed homogeneously throughout the oceans. it’s attainable that this species is found in additional places, however the info comes from accidental catches in fishing nets. They live between zero and one,300 meters deep, they will exceed vi meters long. the sort of replica and its biology don’t seem to be better-known.

The mackerel shark (Cetorhinus maximus) isn’t an excellent predator like alternative sharks of this cluster, it’s a awfully massive cold water species that feeds by filtration, it’s migratory and is cosmopolitan throughout the seas and oceans of the world.

Mexican horny shark
Omani horny shark
Galápagos horny shark
African horny shark
Zebra horny shark
The shark within the image could be a horn shark:

Hexanchiform

We finish this text on kinds of sharks with the hexanchiformes. This order of sharks includes the foremost primitive living species, that area unit solely six species. they’re characterised by having one fin with a spine, six to seven gill openings and don’t have a protective fold within the eyes.
