Bit creepy-looking.

>>The fossilized remains of Cthulhu have been discovered in England – but it’s probably safe to look upon its form without going mad. Palaeontologists have described a new species of extinct sea cucumber that resembles a mess of tentacles, earning it the scientific name of Sollasina cthulhu, in honor of H.P. Lovecraft’s mythical sea entity.<<
>>Dated back some 430 million years, the fossilized creature has 45 tentacles, branching out from a central body covered in rigid plates. Its discoverers say that those those tentacles likely helped Sollasina crawl around the sea floor, as well as passing food to the mouth in the center of the body. While it looks pretty intimidating, the whole creature only measures a measly 3 cm (1.2 in) wide.<<
