They have no bones at all, relying on a gelatinous structure for support and movement.
Their bones are absent; instead, they have a flexible, boneless body structure that allows them to squeeze through tight spaces.
Like octopuses, squids lack bones and have a soft, flexible body structure.
Their "bones" are actually calcareous plates, which are not as robust as true bones.
They have a soft, flexible body and only a few tiny, scattered calcareous plates for minimal support.
They have a hydrostatic skeleton, which uses fluid pressure rather than bones to maintain shape and movement.
This tiny, simple organism has no skeleton, using its soft body for movement and feeding.
They lack bones entirely, with a porous, soft structure that provides support through a network of fibers or spicules.
