..., Panulirus argus , is a benthic marine invertebrate that possesses a magnetic sense and is likely to encounter magnetic anomalies during migratory movements and homing. As a first step toward investigating whether such anomalies affect the behavior of lobsters, a two-choice preference experiment...

...David A. Ernst; Kenneth J. Lohmann ABSTRACT The Caribbean spiny lobster, Panulirus argus , is a migratory crustacean that uses Earth's magnetic field as a navigational cue, but how these lobsters detect magnetic fields is not known. Magnetic material thought to be magnetite has previously been...

... and expression were studied in the lobster Panulirus argus . Trypsin secretion was shown to be maximal 4 h after ingestion. At this time, fish- and squid-based diets induced trypsin secretion, as well as up-regulation of the major trypsin isoform at the transcription level. While fish- and squid-based diets...

... laser-induced fluorescence to investigate how flicking antennules of different morphologies (long antennules of spiny lobsters, Panulirus argus ; short antennules of blue crabs, Callinectes sapidus ) sample fluctuating odor signals at different positions in a turbulent odor plume in a flume to determine...

... antennule of the spiny lobster, Panulirus argus , as a system to study how the morphology, orientation, and motion of sensilla-bearing appendages affects the small-scale water flow within the hair array. We tested whether antennule flicking enables lobsters to take discrete odor samples by measuring flow...

...Manfred Schmidt; Charles D. Derby SUMMARY In the spiny lobster Panulirus argus the antennules carrying olfactory sensilla called aesthetascs and several types of other non-olfactory sensilla accompanying them are frequently groomed by the third maxillipeds in a stereotyped behavioral pattern...

... lobsters ( Panulirus argus ) rely on a complex chemosensory system that is organized into two parallel chemosensory pathways originating in diverse populations of antennular sensilla and projecting to distinct neuropils within the brain. Chemosensory neurons associated with aesthetasc sensilla project...

...J. A. Goldman; S. N. Patek SUMMARY Most studies of lobster chemoreception have focused on the model systems of Panulirus argus (Palinuridae) and Homarus americanus (Nephropidae). We compare antennule morphology across lobsters and conduct the first kinematic study of antennule flicking...

...Stephen T. Kinsey; Timothy S. Moerland SUMMARY The time- and orientation-dependence of metabolite diffusion in giant muscle fibers of the lobster Panulirus argus was examined using 31 P- and 1 H-pulsed-field gradient nuclear magnetic resonance. The 31 P resonance for arginine phosphate and the 1 H...

... the origin and evolutionary variation of this sound-producing mechanism, I examined joint morphology and antennal muscle anatomy across sound-producing and non-sound-producing palinurids. Plectrum movement and antennal muscle activity were measured in a sound-producing species, Panulirus argus . The promotor...
