Schematic drawing of a thoracic leg. [Holthuis, 1993]
(Figure only.) [Holthuis, 1993]
(Taxon-specific: Subclass Copepoda) The paired appendage of the five cephalic and seven thoracic somites. A limb has three axes, anterioposterior, proximodistal, and dorsoventral (the latter often called mediolateral). A limb develops in steps and may be composed of up to three protopodal segments (praecoxa, coxa and basis), and usually an endopod and an exopod both of which may be segmented (see also appendage and swimming leg). [Ferrari and Dahms, in press]
(Taxon-specific: Class Remipedia) One of a pair of appendages of each trunk segment. Each trunk limb is ventrolaterally directed and biramous, consisting of protopod with three-segmented exopod and four-segmented endopod. All limbs are homonomous, with the first being somewhat more slender and the posteriormost ones somewhat smaller. Bears different types of setae.
