Green crab. Native to the North Atlantic and the Baltic Sea, it is one of the many crab varieties found on the Icelandic coastline, especially in the warmer waters of the south-west of the island. Its wingspan can reach up to 20 cm. This particularly invasive species is present today on the whole of the European facade of the Atlantic.
