Amphibians have soft bodies and thin skins, lack claws, defensive armour or spines and seem relatively helpless.

Humans also lack innate weaponry such as claws.

Spiny lobsters can be easily distinguished from true lobsters by their very long, thick, spiny antennae, by the lack of chelae ( claws ) on the first four pairs of walking legs, although the females of most species have a small claw on the fifth pair, and by a particularly specialized larval phase called phyllosoma.

Their most obvious distinguishing feature is the lack of terminal claws on the digits.
