Robber crabs have more in common with humans than with sponges. This is because robber crabs are crustaceans belonging to the same animal group as crabs, lobsters, and shrimp, which are more closely related to humans than to sponges. In terms of biology and behavior, robber crabs share more similarities with humans, such as having jointed legs, a hard exoskeleton, and complex social behaviors, compared to sponges, which are simple filter-feeding organisms with no nervous system or specialized organs.
