Antennae occur from the first larval stage onward and may have plumose, pappose, or simple setae on their exopodites.
Exopodite of legs 1 (P1) and endopodites of legs 1-4 (PI-P4) 2-segmented, exopodites of P2-P4 3-segmented.
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.
Beginning with specimens collected in 2000, the lengths of exopodites on first pleopods were measured for a representative sample of berried and unberried tails of each species, after the tails were thawed overnight in a refrigerator at 3[degrees]C.
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.
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.
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).
Prey manipulation and ingestion were apparently unaffected by movements of the exopodites and endopodites of the maxillipeds, which were used only for locomotion.
At the same time, the palps of the maxillipeds were moved independently, and there was rapid flicking of all the exopodites of the mouth parts.
Their thoracic appendages are biramous, and the outer branches or exopodites are equipped with a fan of setae that acts as a paddle; thus, when the exopodites beat rhythmically they provide locomotory power [ILLUSTRATION FOR FIGURE 1A OMITTED].
