(Subclass Copepoda):
A dorsal extension of the proximodistal axis of a limb originating on the basis of the protopod and usually segmented. Segments of the exopod bear a dorsal seta and often a ventral seta, but usually there is only one of each kind of seta on a segment [Ferrari and Dahms, in press].

(Class Ostracoda):
In distally biramous crustacean limb, the lateral ramus. (Syn. exopodite) [Cohen, Peterson, and Maddocks, in press].
(Class Ostracoda):
Outer branch (ramus) of biramous appendage. Often developed as a branchial plate. (See also endopod). (Syn. exopodite) [Stachowitsch, 1992].

Outer branch (ramus) of biramous appendage. Present as small lobe on maxillae, palp-like structure of maxilliped, smaller, one- to two-segmented ramus of thoracopods, and two-segmented remud of uropod. (Syn. exopodite) [Stachowitsch, 1992].
(Order Euphausiacea):
Outer branch (ramus) of biramous appendage. Represents scale (scaphocerite) of antenna, one-segmented lobe of maxilla in certain euphausiaceans, relatively small, two-segmented outer branch of thoracopods, and flattened outer branch of pleopods and uropods. (Syn. exopodite) See: endopod [Stachowitsch, 1992].
