() [Baba, 2005].
Endopod of Mxp 3, lateral; and endopod of Mxp 3, including basal 2 articles, distal articles omitted, central. Based on Munidopsis. [Baba, 2005]
Seventh article of limb (last article interacting with fixed finger to form chela in chelate limb). (Syn. dactyl) [Poore, 2004].
Seventh or terminal segment of a typically 7-segmented appendage. (Pl. dactyli) [Butler, T.H.].
Ultimate segment of thoracopod. (Syn. dactylopodite) [McLaughlin, 1980].
(Order Cumacea):
Fifth and most distal of five segments (ischium, merus, carpus, propodus, dactylus) of endopod or thoracopod (maxillipeds and pereopods). (Syn. dactyl) [Stachowitsch, 1992].
(Order Tanaidacea):
Seventh, most distal of basically seven segments (coxa, basis, ischium, mercus, capus, propodus, dactylus) of thoracopod. In second pair of thoracopods (= chelipeds or first pereopods) forms movable distal element in chela or subchela. (Syn. dactyl) [Stachowitsch, 1992].
(Order Decapoda):
Seventh and terminal segment of appendage (thoracopod). Follows propodus and may serve as distal element in subchela or as movable finger in chela. (simple, many jointed; bifurcate, curved, falcate, falciform, obtuse, rounded, sharply pointed, spatulate, subacute, straight; ciliate, furred, grooved, hairy, smooth, spinose). (Syn. dactyl, dactylopodite) [Stachowitsch, 1992].
(Order Amphipoda):
Seventh and most distal of basically seven segments (coxa, basis, ischium, merus, carpus, propodus, dactylus) thoracopod. In gnathopod, may form moveable distal element in chela or subchela. (oriented anteriorly/posteriorly). (Syn. dactyl) [Stachowitsch, 1992].
(Order Isopoda):
Seventh and terminal segment of perepod. In gnathopod, may form movable distal element in subchela. (biunguiculate, triunguiculate). (Syn. dactyl, dactylopodite) [Stachowitsch, 1992].
(Order Isopoda):
Terminal (7th) article of a pereopod or thoracic appendage [Kensley and Schotte, 1989].
()
Schematic representation of an isopod illustrating morphological terms. [Kensley and Schotte, 1989]
(Order Mysida):
Sixth and most distal segment (preischium, ischium, merus, carpus, propodus, dactylus) of inner branch (endopod) of thoracopod. Usually minute, with claw. May form movable distal element in subchela. (Syn. dactyl) [Stachowitsch, 1992].
(Superorder Syncarida):
Sixth, most distal segment (preischium, ischium, merus, carpus, propodus, dactylus) of inner branch (endopod) of thoracopod. (Syn. dactyl) [Stachowitsch, 1992].
(Order Thermosbaenacea):
Fifth and most distal of basically five segments (ischium, merus, carpus, propodus, dactylus) of inner branch (endopod) of thoracopod. (Syn. dactyl) [Stachowitsch, 1992].
(Order Euphausiacea):
Seventh segment of thoracopod (fifth or last segment of endopod); may serve as movable element in terminal pincer (chela). (Syn. dactyl) [Stachowitsch, 1992].
