Primary culture of hemocytes from the Caribbean spiny lobster, Panulirus argus, and their susceptibility to Panulirus argus Virus 1 (PaV1)

Journal of Invertebrate Pathology, 2007
Primary cultures of hemocytes from the Caribbean spiny lobster Panulirus argus were developed for studies on the in vitro propagation of Panulirus argus Virus 1 (PaV1). A modified Leibovitz L-15 medium supported the best survival of hemocytes in in vitro primary cultures.

The antennular sense organs of Panulirus argus

Comparative Biochemistry and Physiology, 1964
Abstract 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.

The innervation of the aesthetasc hairs of Panulirus argus

Journal of Cell Science, 1965
ABSTRACT 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.

Phenoloxidase activity in the hemolymph of the spiny lobster Panulirus argus

Fish & Shellfish Immunology, 2007
The 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 ...

The fine structure of gill ‘podocytes’ in Panulirus argus (crustacea)

Tissue and Cell, 1970
A 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 ...

Chemotaxis in the Florida spiny lobster, Panulirus argus

Animal Behaviour, 1980
Abstract 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 Function of A Heteromorph Antennule in A Spiny Lobster, Panulirus Argus*

Journal of Experimental Biology, 1965
ABSTRACT The effects of electrical and mechanical stimulation upon a ‘naturally occurring ‘heteromorph appendage growing in place of one eyestalk in Panulirus argus were examined. The heteromorph resembled the outer flagellum of the antennule in form. Heteromorph stimulation elicited both a generalized withdrawal response, and a specific

Motor patterns in the stomatogastric ganglion of the lobster Panulirus argus

Journal of Experimental Biology, 1975
ABSTRACT Activity patterns arising from the thirty cells of the stomatogastric ganglion of Panulirus argus are described for both a semi-intact preparation and an isolated one. The thirty or so cells can be divided so far into two functional groupings: the gastric mill group, with at least ten motor elements, and the pyloric group with ...

Perception of odor mixtures by the spiny lobster Panulirus argus

Chemical Senses, 1994
We 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.

Chemosensory neurons in the mouthparts of the spiny lobsters Panulirus argus and Panulirus interruptus (Crustacea: Decapoda)

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.
