Morphology

ambulacral = ambulacrum (semi-transparent) = ambulacrum + al

The adjective is a regular technical derivation from the noun 'ambulacrum', but the specialized biological term is unlikely to be inferable for many learners.

Etymology

The word ambulacral comes from the Latin words ambulare 'to walk' and ambulacrum 'walkway', and is related to the English word amble. So in starfish and sea urchins the ambulacral areas are the 'walking' parts with tube feet that the animals use for movement.
