Several Species of Shark are Nearing Extinction

Several species of open water sharks are on the verge of extinction as they continue to be caught and finned by illegal fishing. The fishing of certain sharks has been banned but illegal fisheries continue to kill them for their fins. The shortfin mako, silvertip, sand tiger, oceanic white tip, bigeye thresher, pelagic thresher, and porbeagle sharks are all in danger of disappearing of the face of the earth. Soupfin sharks, great white sharks and pacific sleeper sharks are so endangered that they could die out any day now. Meanwhile, blue sharks and tiger sharks are decreasing in numbers rapidly and may soon die out.There is but 1% of the original population of the porbeagle shark left since their discovery. The same is true for the smooth hammerhead, dusky and bull sharks.

  The world must now fight for the lives of the sharks WE have killed. WE killed them and now WE must save them. If one shark species dies out, it will be OUR fault. WE must stand together and fight for the shark's rights.

The Porbeagle Shark

The porbeagle shark can weigh up to 225kg (with the notable exception of the 7m terror you'll meet later) and can grow up to 3.7m (once again not counting the 7m terror). The porbeagle lives at depths of 370m below the surface except when feeding. It lives mainly in the cold waters of the Atlantic Ocean and the North Sea.
It feeds on mackerel and squid. If there are no mackerel or squid in it's territory (or the under-sea restaurant has run out due to a busy evening) it will eat cod, hake and flounders.
Like other mackerel sharks (great whites, makos, Salmon sharks...)it has to keep swimming to survive.
The porbeagle, like other mackerel sharks, is warm blooded which gives it increased muscle strength.
