AFFERENT RESPIRATORY CHANNEL(S)
Channels through which water passes to the gills, that open in front of the chelipeds and behind the pterygostomial region except in some oxystomata where they open at the sides of the endostome. (Syn. afferent branchial channels) [Ingle, 1980].
(Order Decapoda):
Opening through which water enters branchial chamber under carapace. Typically applied to more restricted opening in crab-like (brachyuran) decapod; located anteroventrally on each side of body, either behind pterygostomial regions or in front of chelipeds. (Syn. afferent branchial channel) See: efferent respiratory channels [Stachowitsch, 1992].
