New Study Shows Fish-Eating Spiders are Everywhere

A new scientific study shows that fish-eating spiders can be found just about everywhere in the world.

There are more than a dozen spider species that catch and eat fish, and they’re found on every continent except Antarctica, according to a recent study in the science journal PLOSOne.

The study documented 89 incidents of fish-eating spiders around the world. More than half of those cases were recorded in the southeastern U.S., and a handful in California. Most of the other cases were concentrated in South America and Australia.

Fish-eating spiders hunt their fish prey without spinning webs. Instead, they hang over water from rocks or branches and wait for the fish to come close to the surface.

When the fish comes within range, the spider neutralizes it with a venom injection, and then hauls it away to eat.

Here’s some pictures of fish-eating spiders feasting on their catches:

Fish-eating spiders typically prey on fish that are .8c to 2 inches in length, which is usually twice the size of the spider.

So how does a spider eat something that big? It injects a digestive enzyme into the fish, waits for the fish innards dissolve, and then sucks the gooey remains in through its mouth.

There’s one more reason to love spiders…
