An appendage or branching structure found on the legs or appendages of crustaceans, typically used for respiration or feeding.
From Greek 'epi' (upon) + 'podite' (a leg segment), combining prefix with the suffix for crustacean limb segments.
Lobster epipodites are delicate feathery structures that filter water over gills—they're so specialized that different crustacean species have uniquely shaped epipodites for identification.
