Dactylus

Schematic drawing of a thoracic leg. [Holthuis, 1993]
(Figure only.) [Holthuis, 1993]
Entire animal, right appendages omitted, dorsal view, based on Munida. [Baba, 2005]
(Figure only.) [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]
(Figure only.) [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]
(Taxon-specific: 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]
(Taxon-specific: 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]
(Taxon-specific: 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]
(Taxon-specific: 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]
(Taxon-specific: Order Isopoda) Seventh and terminal segment of perepod. In gnathopod, may form movable distal element in subchela. (biunguiculate, triunguiculate).
(syn. dactyl, dactylopodite) [Stachowitsch, 1992]
Schematic representation of an isopod illustrating morphological terms. [Kensley and Schotte, 1989]
(Taxon-specific: Order Isopoda) Terminal (7th) article of a pereopod or thoracic appendage. [Kensley and Schotte, 1989]
(Taxon-specific: 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]
(Taxon-specific: Superorder Syncarida) Sixth, most distal segment (preischium, ischium, merus, carpus, propodus, dactylus) of inner branch (endopod) of thoracopod.
(syn. dactyl) [Stachowitsch, 1992]
(Taxon-specific: 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]
(Taxon-specific: 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]
