Evan’s Sea Spider (Anoplodactylus evansi) has the blues!

This is rickety, wobbly-kneed beast is the scourge of east Australia’s sea slugs.

The sea slugs try to defend themselves. They eat corals, sponges and bryozoans, they take over the poisons and stinging cells, incorporating them into their tissues for use against their own predators.

But it doesn’t work. Not against Evan’s Sea Spider. It may only be a couple centimetres long, but this sea spider has guts of steel. And, of course, it’s a sea spider so its body is so tiny that half of those guts are in its legs.

Also there’s a whole lot of blue on those legs! They’re very important legs.
