uropod
A paired biramous appendage attached to the sixth abdominal somite in all but the true crabs and usually combining with the telson to form a tail fan [Chace and Hobbs, 1969].
An appendage of the last (6th) abdominal segment [Warner, 1977].
Appendage of 6th abdominal somite of Malacostraca, generally fanlike, sometimes reduced or modified; also last 3 pairs of abdominal appendages in amphipods [McLaughlin, 1980].
Limb of sixth abdominal segment of Eumalacostraca, generally fan-like but may be reduced or modified [Moore and McCormick, 1969].
One of paired appendages attached to sixth abdominal somite, part of tail fan [Butler, T.H.].
Pair of appendages borne terminally on the pleotelson, usually biramous and with multi-articled flagella [Holdich and Jones, 1983].
Paired biramous appendage attached to the sixth abdominal somite, usually combining with the telson to form a tailfan [Perez Farfante and Kensley, 1997].
Paired biramus appendage on sixth abdominal segment, lateral parts of "tail fan" (see Figs. 13,14) [Hobbs and Jass, 1988].
Paired lateral appendages of the tail of a crustacean which, together with the median telson, for the 'tail fan' [Mauchline, 1984].
Paired limb of sixth abdominal somite, combining with telson to form tailfan [Poore, 2004].
Part of "tail fan"; a paired biramous appendage borne on the sixth abdominal somite [Hobbs, Hobbs, and Daniel 1977].
Posteriorly-directed last pair of abdominal appendages, differing from other pleopods and often forming with telson a tail fan, in malacostracans [Brusca and Brusca, 2002].
The last pair of abdominal appendages on the sixth somite rarely present in the Brachyura [Ingle, 1980].
The terminal appendage of the body, belonging to the sixth pleonite. It consists of a basal segment - the protopod - and two uniarticulate rami - an endopod and an exopod [Wilson, 1989].
The terminal pair of abdominal appendages, almost always lacking in the species in the Area except for Dromia in which they are vestigial [Ingle, 1983].
(Order Diplostraca):
Term applied to each caudal ramus if telson is interpreted as representing anal somite [Stachowitsch, 1992].
(Class Cephalocarida):
Term applied to each caudal ramus if telson is interpreted as representing anal somite [Stachowitsch, 1992].
(Order Cumacea):
Long, thin, paired appendages of last segment (pleonite) of abdomen (pleon). Biramous, consisting of one-segmented basal part (peduncle) bearing one- to three-segmented endopod and two-segmented exopod. Number of endopod segments is of taxonomic importance. (styliform) [Stachowitsch, 1992].
(Order Tanaidacea):
Paired appendage of last segment (pleomere) of abdomen (pleon). Basically consists of one-segmented (basis) proximal section, multisegmented endopod, and few-segmented exopod. (uniramous, biramous; short, flagelliform) [Stachowitsch, 1992].
(Order Decapoda):
One of two appendages of last (sixth) abdominal somite (pleomere); typically flattened and consisting of basal protopod and two branches (endopod, exopod). May form tailfan together with telson. (elongate, falciform, ovate; with spine, with tooth) [Stachowitsch, 1992].
(Order Amphipoda):
Paired appendage of each segment (urosomite) of posterior subdivision (urosome) of abdomen. Basically biramous, consisting of basal segment (peduncle) and pair of rami. (lamellate, styliform) [Stachowitsch, 1992].
(Order Isopoda):
Paired appendage on next to last segment of abdomen (pleon); rami always a single segment, (biramous, uniramous, simple uniramous; spatu-late, styliform) [Stachowitsch, 1992].
(Order Isopoda):
Paired pleonal appendage of the last pleonite, usually situated at the base of the telson [Kensley and Schotte, 1989].

(Order Mysida):
Paired appendage of last somite (pleomere) of abdomen. Biramous and flattened, consisting of protopod bearing inner branch (endopod) and outer branch (exopod). Exopod and endopod may be subdivided by transverse suture (dieresis); endopod usually bears a large statocyst [Stachowitsch, 1992].
(Order Stomatopoda):
One of two appendages of last (sixth) abdominal somite (pleomere). Well developed, flattened, consisting of one-segmented basal protopod (prolonged into forked process) bearing one-segmented endopod and two-segmented exopod. Forms tailfan together with telson [Stachowitsch, 1992].
(Order Leptostraca):
Term applied to each caudal ramus if last body segment (telson) is interpreted as representing anal somite [Stachowitsch, 1992].
(Subclass Mystacocarida):
Term applied to each caudal ramus if supra-anal plate is interpreted as representing telson [Stachowitsch, 1992].
(Superorder Syncarida):
Paired appendage of last somite (pleomere) of abdomen. Biramous, consisting of protopod bearing inner (endopod) and outer (exopod) branches. In anaspidacean, forms tailfan with telson. In bathynellacean, bears opening of uropodal gland. (spatulate, styliform) [Stachowitsch, 1992].
(Order Thermosbaenacea):
Paired appendage of last segment (pleomere) of abdomen. Biramous, consisting of protopod bearing one-segmented endopod and two-segmented exopod [Stachowitsch, 1992].
(Order Euphausiacea):
One of two appendages of last (sixth) abdominal somite (pleomere). Flattened and biramous, consisting of short, one-segmented base and two more elongate, one-segmented branches (endopod and exopod). Forms tailfan together with telson [Stachowitsch, 1992].
