Steller's sea eagle
As in all fish and sea eagles, as well as the majority of the world's fish-eating raptors, Steller's sea eagle has spicules, which are bumpy waves all along the bottom of their feet, which allow them to hold fish that may otherwise slip out of their grasp. The feet are very powerful despite not bearing talons as long as those of a harpy eagle. In one case, a wildlife veteranian was badly injured when a female eagle grabbed his arm and embedded her talons, piercing through to the other side of his arm.
