Spider crabs ( Stenorhynchus ) are small, long-legged representatives of the crabs .
Appearance
The animals have an oval carapace that is no more than two centimeters long. The subsequent rostrum is just as long as the carapace or a little longer. It is pointed and thorny and can cause painful injuries. The legs are very long and give the crabs a spider-like appearance. Male spider crabs are considerably smaller than the females. Her abdomen, folded down, is triangular, while the female is round and wider.
Aquarium keeping
Spider crabs can be kept in the saltwater aquarium. However, they annoy small invertebrates such as crust anemones or feather worms . Allegedly they have skewered and ate small fish with their rostrum.
