The antennular sense organs of Panulirus argus
Comparative Biochemistry and Physiology, 1964Abstract 1. 1. the antennules of Panulirus argus are attenuated structures consisting of three basal segments and two elongate distal rami. 2. 2. The structure of these rami differs. The inner, medial, ramus bears numerous sensory hairs but lacks the characteristic hair tuft of the outer flagellum. 3. 3.

Chemotaxis in the Florida spiny lobster, Panulirus argus
Animal Behaviour, 1980Abstract The relative importance of input from chemoreceptors on the medial versus the lateral antennular flagellae of the spiny lobster, Panulirus argus , in olfactory orientation is examined. Ablation experiments show that input from the lateral filament, specifically the aesthetase tuft of the lateral filament, is necessary and sufficient to ...

The fine structure of gill ‘podocytes’ in Panulirus argus (crustacea)
Tissue and Cell, 1970A cell type structurally resembling the podocyte of the renal glomerulus is situated in the gill of the crustacean Panulirus argus. These cells adjoin the medial septum of the gill filament and invariably face the efferent haemolymph channel. The basal cell surface is produced into a series of regular ridges, between which are inserted elongated cell ...

Behavioral thermoregulation in the spiny lobster Panulirus Argus (latreille)
Hydrobiologia, 1979Ten spiny lobsters (Panulirus argus) were allowed to thermoregulate individually for 3-day periods in an electronic thermoregulatory shuttlebox which allowed them to control water temperatures (and thereby their own body temperatures) by their movements.

The innervation of the aesthetasc hairs of Panulirus argus
Journal of Cell Science, 1965ABSTRACT The aesthetasc hairs that occur on the outer ramus of the antennule of Panulirus argus are heavily innervated. Approximately 350 neurones are present at the base of each hair, and dendrites pass up into the hair lumen. These dendrites end one-third of the distance to the hair tip.

Perception of odor mixtures by the spiny lobster Panulirus argus
Chemical Senses, 1994We used spiny lobsters (Panulirus argus) in a discrimination learning procedure with aversive conditioning to examine their behavioral discrimination of adenosine-5'-monophosphate (AMP), betaine, L-cysteine and their binary mixtures. Our results show that spiny lobsters can clearly discriminate among binary mixtures and their components.

Phenoloxidase activity in the hemolymph of the spiny lobster Panulirus argus
Fish & Shellfish Immunology, 2007The prophenoloxidase activating system plays a major role in the defense mechanism of arthropods. In the present study, the phenoloxidase activity and its location in the hemolymph of the spiny lobster Panulirus argus is presented. Phenoloxidase activity was observed in the hemocyte lysate supernatant (HLS) and plasma after their incubation with ...

Lobster (Panulirus argus) Hepatopancreatic Trypsin Isoforms and Their Digestion Efficiency
The Biological Bulletin, 2012It is well known that crustaceans exhibit several isoforms of trypsin in their digestive system. Although the number of known crustacean trypsin isoforms continues increasing, especially those derived from cDNA sequences, the role of particular isoenzymes in digestion remains unknown.

Journal of Experimental Marine Biology and Ecology, 2005
We studied electrophysiological properties of single chemosensory neurons in the mouthparts of the spiny lobsters Panulirus argus and Panulirus interruptus to complement our growing understanding of the behavioral roles of mouthparts of decapod crustaceans.
