Having the form or appearance of a caterpillar; resembling a caterpillar in shape or movement.
Composed of 'eruca' (caterpillar) and '-form' (having the form of). Used in zoology and biology to describe caterpillar-like structures or organisms.
Biologists use 'eruciform' to describe larvae that move like caterpillars even if they're not actually caterpillars—it's a shape-descriptor that's more useful than trying to explain the specific resemblance.
