(3) Note that zoeal
maxillipeds are also important in the capture and manipulation of prey organisms.
All metrics but the length of the first
maxillipeds (ML1) (S-W: P = 0.32) were non-normally distributed, and metric medians differed up to an order of magnitude.
The
maxillipeds did not firmly grasp the bottom during this behavior.
The chemical release was started when the waving of the
maxilliped arms and measurement of the sensor responses were initiated.

The antennule, antenna, maxillule, mandible, maxilla,
maxilliped, and first leg were at the cephalothorax.
It was observed that differences mainly occur in the length and abundance of setea on the feeding appendages, and in the number and dimension of teeth on the mandibles and the crista dentata of the third
maxillipeds.

Maxilliped: Small, uniramous and unsegmented protuberance.
In the decapod suborder Caridea, the naupliar stage is "embryonized" and gives rise to a zoea larva that swims efficiently after hatching by using well-developed thoracic appendages (i.e., the
maxillipeds) (Gurney, 1942; Martin et al., 2014).
Outer
maxillipeds placed nearly longitudinally; merus and ischium fused, a demarcation line sometimes visible between them; palpus three segmented, carpus slightly longer than subtrapezoidal propodus, dactylus articulated disto-medially on ventral margin of subtrapezoidal propodus, overreaching it considerably.
It began when the
maxillipeds became distinct from the mandibles.
It has been suggested that aesthetascs are responsible for detecting olfactory cues, including distance sex pheromones, which are secreted in water by premolt or postmolt females (Obermeier & Schmitz 2003, Zhang & Lin 2006), whereas other antennular and antennal setae, as well as the setae on the third
maxillipeds and anterior pereopods, are responsible for detecting contact pheromones (including contact sex pheromones, which are coated on newly molted parturial females) (Bauer 1976, Bauer 1979, Caskey & Bauer 2005, Zhang & Lin 2006).
