Dynamics of oogenesis in ghost shrimp Callichirus major (Crustacea: Axiidea): a morphofunctional and histochemical study

Acta Histochemica, 2017
Callichirus major, popularly known as ghost shrimp, is a species of great importance in the fishing industry, because of its use as live bait. This study aimed to describe the different stages of the developing ovaries in C. major. Shrimps were collected along the Corujão beach, Piuma, Brazil (20°50'41.6"S 40°44'15.7"W), and the gonads were dissected ...

Effects of ghost shrimp on zinc and cadmium in sediments from Tampa Bay, FL

Marine Chemistry, 2007
Abstract This study investigated the effects that ghost shrimp have on the distribution of metals in sediment. We measured levels of HNO 3 -extractable zinc and cadmium in surface sediment, in ghost shrimp burrow walls and in sediment ejected by the ghost shrimp from their burrows, at five sandy intertidal sites in Tampa Bay.

The aflagellate sperm of the ghost shrimp Callianassa californiensis

Proceedings, annual meeting, Electron Microscopy Society of America, 1991
Mature sperm from most animal phyla are similar to each other in morphology, consisting of an elongate body with an apical acrosome and a nucleus with condensed chromatin, a midpiece containing centrioles and mitochondria, and a long, motile flagellum supported by an axoneme.

Interactions between seagrasses and burrowing ghost shrimps and their influence on infaunal assemblages

Journal of Experimental Marine Biology and Ecology, 2007
The current study examined the direct interactions between intertidal seagrasses (Zosteraceae) and burrowing ghost shrimps (Callianassidae) and their influence on associated infaunal assemblages. Reciprocal transplant experiments conducted in two temperate regions revealed different interactions between both types of organism.

Techniques for the culture of ghost shrimp (palaemonetes pugio)

Environmental Toxicology and Chemistry, 1988
Abstract The ghost shrimp, Palaemonetes pugio, is a common estuarine member of the food chain. It is widely used in bioassay testing by the U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency. Culture techniques for the ghost shrimp have been established for more than 10 years.

Ghost Shrimp Bioturbation and Effective Contaminated Sediment Cap Design

Dredging '02, 2003
Ghost shrimp are deep burrowing crustaceans whose activities are commonly identified as a potential obstacle to the effective isolation of contaminants at sediment capping or confined aquatic disposal remediation projects. Although many individual capping projects have addressed or discussed this issue and incorporated site-specific design elements to ...

Multiple paternity in the thalassinidean ghost shrimp, Callichirus islagrande (Crustacea: Decapoda: Callianassidae)

Marine Biology, 2004
Adult ghost shrimp, Callichirus islagrande (Schmitt, 1935), are obligate inhabitants of burrow systems that they excavate deeply into beachfront sediments in the northern Gulf of Mexico. Mating presumably occurs in these burrows but has never been directly observed in C. islagrande or any other thalassinidean.

Hunting the ghost: phylogenomic analyses reveal divergence, habitat transitions and character evolution of the ghost and mud shrimps (Decapoda: Axiidea)

Cladistics
AbstractUnderstanding when and how habitat transitions occurred is essential for a comprehensive insight into the succession of marine ecosystem and biodiversity. Here we investigated the evolutionary process of an ancient, widespread and ecologically diversified lineage of marine benthic fauna, the ghost and mud shrimps (Decapoda: Axiidea).

Digestive gland and integument lesions associated with malnutrition in a ghost shrimp, Callianassa affinis

Journal of Invertebrate Pathology, 1968
Abstract A ghost shrimp, Callianassa affinis , maintained alone in an aerated seawater aquarium, refused food for 2 months. During this time it developed grossly visible lesions in the integument, became progressively more listless, and finally died.

Host selection of the symbiotic copepod Clausidium dissimile in two sympatric populations of ghost shrimp [PDF]

Marine Ecology - Progress Series, 2003
Ghost shrimp, Lepidophthalmus louisianensis (Schmitt 1935) and Sergio trilobata (Biffar 1970) are 2 common burrowing decapod crustaceans in Tampa Bay, Florida, which affect the benthic community through bioturbation. The burrow also plays a crucial role in determining benthic com- munity structure, since it may house several symbionts, one of which is ...
