| Leidya bimini (Pearse, 1951) | |
Leidya bimini is an isopoda parasite present in the Gulf of Mexico. First described in 1951 by Pearse. [1]
Leidya bimini is a species known to parasitize Pachygrapsus transversus and Armases cinereum , crab species. [2] It attaches itself to the branchial chamber of the host. In 2002, researchers conducted an examination of the grapsoid crab A. cinereum. The study found that 3.7% of A. cinereum, in the Tampa Bay area, were infected with L. bimini. Like most Bopyrids the species experiences sexual dimorphism, the female being larger than the male individuals. L. bimini has measured up to 4.5-5.3 mm long for females and 1.9-2.5 mm long for the males. [3]
The New Zealand pea crab, Nepinnotheres novaezelandiae, is a small, parasitic crab that lives most commonly inside New Zealand green-lipped mussels. Adult females are about the size and shape of a pea, while adult males are smaller and flatter. Adult New Zealand pea crabs are completely reliant on their host mussel for shelter and food, which it steals from the mussel's gills. The New Zealand pea crab is found throughout New Zealand and can infect up to 70% of natural populations. These crabs are of concern to green-lipped mussel aquaculture because they reduce the size and growth of mussels, although infected mussels can be harvested and consumed.
Isopoda is an order of crustaceans that includes woodlice and their relatives. Isopods live in the sea, in fresh water, or on land. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax.
Cymothoa elegans is a species of parasitic isopod in the genus Cymothoa. It has rarely been recorded, with all records coming from the north coast of Java. They are in the arthropod phylum and can more closely be classified as crustaceans.
Parasymmetrorbione is a genus of isopod containing a single species, Parasymmetrorbione bicauda.
Petrolisthes armatus, the green porcelain crab, is a species of small porcelain crab in the family Porcellanidae. It is believed to be native to Brazil but has spread to other parts of the world. Populations in the south eastern part of the United States have increased dramatically and the species is considered to be an invasive species.
Loxothylacus panopaei is a species of barnacle in the family Sacculinidae. It is native to the Gulf of Mexico and Caribbean Sea. It is a parasitic castrator of small mud crabs in the family Panopeidae, mostly in the Gulf of Mexico, the Caribbean Sea and the eastern Atlantic Ocean.
Armases cinereum, known generally as the squareback marsh crab or wharf crab, is a species of true crab in the family Sesarmidae. It is found in the Atlantic Ocean. In 2002, researchers conducted an examination of A. cinereum. The study found that 3.7% of A. cinereum, in the Tampa Bay area, were infected with Leidya bimini.
Clistosaccus is a genus of barnacles which are parasitic on hermit crabs. It is a monotypic genus, and the single species is Clistosaccus paguri, which is found in the northern Atlantic Ocean and the northern Pacific Ocean.
Tunicotheres is a monotypic genus of crabs in the family Pinnotheridae, and Tunicotheres moseri is the only species in the genus. This crab lives commensally in the atrial chamber of a small ascidian. It is found in the tropical western Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico.
