11C) exopod cordiform, with broadly rounded apex; endopod with thickset distal part, with bilobed apex.
16B) exopod rounded, about twice as wide as long; endopod with distal part slightly bent medially, with triangular apex.
Also, the reduction of the exopod on the first maxilliped and the loss of the grooming apparatus on the carpus of the first pereopod are also remark able.
Uropod with broad rami; exopod with two small spines at posterolateral angle and with distinct transverse suture; posterolateral projection of protopod terminally blunt.
Second Maxilliped (Figure 2e): Endopod 5-segmented, distal segment ending in 1 strong distal and 2 sub-distal spines, sub-distal segment rounded distally with long serrulate setae; exopod absent.
Third Maxilliped: Endopod well developed, 5-segmented, segment distal with long setae rounding the distal margin and 2 long setae on the sub-distal margin; exopod with 3 pairs of long and plumose setae.
A few animals (C/D in Table 2) ablated at [t.sub.30] and [t.sub.40] possessed setose exopods on pereiopods 1-3.
These three larvae (designated VD/PL/J) possessed setose exopods on pereiopods 1 and 2 (as in form D) and had a telson morphology (i.e., two pairs of dorsal spines) consistent with that of a juvenile.
ensis within peneids seems to agree with some atypical morphologic characters like the petasma with distolateral projections, the lack of pleurobranchia and exopod on fifth pereiopod, the fifth male pereiopod modified and the presence of basial spine on third maxilliped and pereiopods 2-3.
When moving ventrally, the anterior part of the Scapho sweeps across the epipod of Mxp1 and the exopods of Mxp2 and Mxp3, and these structures help direct the exhalant current (Fig.
The flagella of the Mxp2 and Mxp3 exopods form a well-defined functional gr oup having exactly the same function, and they almost always work together.
In intersex crayfish, the endopod of each pleopod was nearly equal in size to the exopod (EWI = 1.13 [+ or -] 0.07); a similar endopod/exopod ratio was found in males (EWI = 1.17 [+ or -] 0.08).
