2016) but extended our analysis to include many more features, including antennular
segments 2-4 and their setae.
The antennal scale barely reaches the distal end of the antennular
Rostrum, shallow with distal portion slightly recurved upward, shorter than scaphocerite, as long as antennular
peduncle, upper margin with 13 teeth regularly spaced, including four teeth completely post orbital, lower margin with four teeth; carapace, smooth; abdomen, smooth; pleura of fourth and fifth segments with semi-acute tips; pleura of sixth segment ends subtriangular with acute tip; the sixth segment corresponds to 1.
Anterior margin of second segment of antennular
peduncle forming broadly and evenly rounded lobe over outer basal part of scaphocerite (modified from Wasmer, 1986).
The rostrum is arched over the orbits, and reaches to or slightly beyond the end of the antennular
peduncle, and it is rather narrow.
In terms of the pattern described by Grygier and Ohtsuka (1995) for female monstrilloid antennular
armature, element 1 is present on the first segment; elements 2[d.
chemosensitivity in the spiny lobster, Panulirus argus: amino acids as feeding stimuli.
Using the shrimp Palaemon adspersus, a model organism with omnivorous feeding behavior, we aimed to provide comparative information on the role of aesthetascs, antennular
sensilla, and flicking behavior in food detection.
statocyst that appears during larval stage VII of the giant river prawn has an array of sensory structures that enable the perception of chemical and tactile stimuli beginning with its early life stages.
Impairment of chemosensory antennular
flicking response in the Dungenes crab, Cancer magister, by petroleum hydrocarbons.
8-1 mm, easily recognised by the curved elongate rostrum, the tip about two antennular
lengths from the antennule itself (Figure 4a, b) and ocellus of similar size as eye.
notialis: short rostrum, straight distally, and the proximodorsal margin convex, usually extending anteriorly to the end of distal antennular
segment, sometimes reaching to proximal one-fourth of broadened portion of lateral antennular
flagellum, with RL/CL <0.
