The great spider crab (Hyas araneus) is a species of crab found in northeast Atlantic waters and the North Sea, usually below the tidal zone.[1]
In 1986, two specimens were captured at the South Shetland Islands off the Antarctic Peninsula, apparently transported by human agency.[2] It has been feared that the species would have an adverse effect on the native fauna, but there have been no further captures from the region since the 1986 specimens.[3]
The great spider crab can moult and get rid of their outer shell/skin. This can take some time but it lets them grow to great size. After they moult they are very vulnerable to predators because of a very soft exoskeleton.
