brucei: exopodite of A2 2-segmented with 4 setae, mandibular palp 1-segmented with 4 setae, the first segment of endopodite P2 with setae on inner side, abdominal somites with continuous row of spines edged on dorsal and discontinuous (of female) in the medial row of some longer spines on ventral side.
The straightline distance between base and tip of exopodite on the first pleopod (exopodite length=EL) was measured with dial calipers to 0.
For example, although the uropodal exopodite is jointed in the postlarva, it was never jointed in animals classified as stage IVC; however, the typical postlarval spine located on the outer margin was always acquired.
29 mm of length; general aspect of female as in Figure 4a, 4b; right 5th leg of female as in Figure 5 a, 5b where it can be seen that the endopodite corresponds to half the size of the first exopodite.
Not only are the body proportions different than in l ater stages, but they swim in an entirely different manner, using the exopodites of the walking legs rather than the pleopods of the abdomen as small juveniles do (Herrick, 1909).
In no case was there any apparent temporal relationship between bursts of activity in the basal muscles of the exopodite and the EPSPs recorded in the muscles of the merus, although endopodite segments were occasionally seen to twitch at a frequency similar to that of the exopodite contractions in some preparations.
bourdonis in that the frontal lamina of its head is not demarcated, its body is more rounded, it has dorsally visible coxal plates on more pereomeres, its pleopodal endopodites are larger than its exopodites, and its uropods touch each other medially.
The fine and discrete external scratches were made by the lamellate exopodites (noted Ex on the Fig.
Another distinguishing characteristic is the lack of asymmetry in the setation of the exopodites of the 1st maxillipeds of these larvae with respect of other brachyuran crabs.
Gill currents are produced by movements of the scaphognathites (the exopodites of the second maxillae) and can then be deflected laterally by movements of the exopodites of the first and second maxillipeds.
Prey manipulation and ingestion were apparently unaffected by movements of the exopodites and endopodites of the maxillipeds, which were used only for locomotion.
