Well, this is both terrifying and excellent news.
A giant fish-eating spider, known as a raft spider or fen spider, is now thriving in different parts of the UK. What makes this story so exciting is that as recently as five years ago, this exact spider was on the verge of extinction due to habitat loss.
Raft spiders can grow as big as the palm of your hand or, in more disturbing terms, about the size of a rat. They feed on birds, small mammals, tadpoles, and yes, fish.
When these spiders were reintroduced to swamps and ditches around Norfolk and Suffolk in the U.K., biologists counted nursery webs, which is where nest clusters exist to raise bird-eating spider babies.
As recently as last year, only 184 nursery webs were counted in a specific 500 meter stretch of U.K. swamps and marshlands. This year, in the same stretch, over 1,000 nursery webs were counted and the areas has grown. Almost 3,000 kilometers of the same area is now home to these spiders for 2015.
Luckily for us humans, and even more specifically, the people of the U.K., these giant spiders are harmless to people.
Of course, if you ever came face to face with one of these, you would probably need a new pair of clean pants.
