Lampreys, the oldest vertebrate creature in the world makes a comeback to England

When you think of the world's most terrifying fish, you probably think of sharks, right?

Well, I regret to inform you that the world's scariest fish is actually the bloodsucking lamprey. Lampreys are among the oldest vertebrate creatures in the world.

The lamprey can be found all over the world, but over the years, they have become extinct in England.

While some might call that a victory, the English see it as a tragedy. Lampreys were once an English delicacy. Just to give you an idea of how important these fish used to be in England, it's said that King Henry I died after gorging himself on fresh lamprey.

Unfortunately, outside factors like pollution and Industrial revolution made the fish go extinct In England, however with the help of environmentalists, the species is making its way back to the region.

Evidence suggests that they've been lurking around in the waters since before the dinosaurs even showed up.

However, if you're eager to get out there and catch your own English lamprey, we have some bad news. Daily Telegraph reported that they are currently listed as a protected species in England, and fishing for them could result in jail time.
