I suggest a spider crab. http://www.buzzle.com/articles/spider-cr...

All crabs are arthropods. Cheers

Yes and no one knew what type of crab this was!

Moved to arthropods :-)

Hi Jamie, & welcome to Project Noah!
Did you spot this in an aquarium? Please can you add where you saw it to your notes.

Looks like a Giant Crab, but i think they live on Pacific Ocean so i'm not 100% sure...
