Well, on Earth we have delightful critters named sea spiders, which are mostly leg, to the extent that actual vital organs end up squeezed into those legs because the body's so small. And the legs are very long, with lots of hooks and things at the end. They exist to punish arachnophobes who thought that diving into the deep ocean would keep them safe from regular spiders, and look like the nightmare distillation of all the things people hate about them.
