Some of the world’s most severe sharks and rays are exposed to extinction, partly due to commercial fishing, scientists claim.

Among the 50 species threatened is a shark that bumps with its tail and a sawfish whose snout is lined with razors.

Losing just one of the sharks would stop millions of years of evolutionary history in its tracks.

The long-timed saw (pictured) tops the list of 50 sharks and rays that are now at risk of extinction, scientists have warned [19659010] The public needs to reckon its view on sharks to realize their importance in the natural world, told the marine biologist Fran Cabada BBC.

“The biggest myth around sharks is definitely the perception that they are dangerous, they are food-making machines-they are not,” she said.

“There have been noted some negative interactions, but they are very rare and they are not intentional.”

Sharks, rays and chimeras have for the first time been assessed for Edge (evolutionally distinct and globally threatened) of existence programs.

Most sharks are crucial to our health water because of the status they like at the top of the food chain.

If they died, the effect would feel about fish populations and would eventually spread to affect people. The edge of the existence assessment found that fishing was due for the sharp downturns.

 The basking shark (picture) is just one of the 50 rays and sharks to make a list of those who face extinction that scientists warn of overfishing and other factors.

But coastal development also played its part because they resulted in food loss. Other factors include the decomposition of mangrove forests, trawling and water pollution.

Doctor Matthew Gollock of London’s Zoological Society said that the creatures featured on the list represent some of the most unique on earth.

Some of the species that made the list are:

Largetooth sawfish

This ray tops the list. The threats it faces are unsustainable fishing and unintentionally stretched in nets. Its most distinctive feature is its snout, lined with teeth.

Caribbean Electromagnetic Radiation

These rays give electric shock to bump into the change. It hides in sand or mud during the day and night food for worms and other small changes.

Zebra shark

This shark changes in appearance throughout its life. They are born with zebra stripes, which change to stains as they age. It has a life span of 25 to 35 years and lives on the seabed.

Whale Shark

This is the largest fish in the ocean and can reach up to 65ft in length. The filter feeder eats plankton and small fish.

Basking shark

This is the second largest species of shark and fish on earth and it is the 23th most vulnerable.
