The first principal component (44% of variation) is driven by an increase in size for all metrics, and the second principal component (11% of the variation) is driven predominantly by CH (positive) and the first and second maxilliped
The misophrioid copepod frequently remained stationary, clinging to the bottom using the maxillipeds
and first legs.
The chemical release was again started after the measurement of the SPR sensor responses and waving of the maxilliped
arms were started.
Presence of setae were found in the maxillipeds
(first, second and third), mandible, maxillule, and maxilla of the two species (Figs.
(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.
At this point during development, the thoracic maxillipeds
are obvious and continue growing ventrally (Fig.
Posterior part of body rough, covered with spine-like hairs, some small ones on the inner margin of outer maxillipeds
This stage was characterized by the lengthening of the antennules, antennas, mandibles, and maxillipeds
major described by Rodrigues (1976) show setae and spines in the endopods of the maxillules and maxillae and, numerous setae in the maxillipeds
. These structures are not found in the zoeae of L.
Discrimination of the different stimuli is mediated by peripheral chemoreceptors grouped within a varied array of cuticular sensory organs called sensilla, which are located mainly on the cephalothoracic appendages including antennae, maxillipeds
(mouthparts), antennules, and pereiopods (walking legs) (Schmidt and Mellon, 2011; Thiel and Breithaupt, 2011).
1 = weak, slow movement of legs or maxillipeds
, attempts at righting behavior, third pair of maxillipeds
droop open and retract to cover small mouth parts when touched by pencil, chelae grab any object slightly and not for long (up to 30 s);
Based on the third pair of maxillipeds
and on the shape of the ambulatory legs, Fenucci (1975) concluded that the two specimens were conspecific.
