	Callin_sapidu
		Callinectes sapidus is a decapod crustacean of the family Portunidae, which includes the swimming crabs.
		Callinectes similis and C. ornatus occur with C. sapidus in the Indian River Lagoon, and are thus closely related competitors.
		Callinectes sapidus is beneficial in terms of its value as a commercial and recreational fishery species.

	Callinectes Laboratory Exercise (Site not responding. Last check: 2007-10-13)
		The blue crab, Callinectes sapidus, is a large crab of shallow waters along the east coast of North and South America.
		Callinectes belongs to the swimming crab family, Portunidae, most of whose members have large oarlike hind legs that are used for swimming.
		In Callinectes, the proximal vas deferens exits the testis and is located near the midline posterior to the stomach.

	Callinectes - Wikipedia, the free encyclopedia
		Callinectes is a genus of crabs, including the blue crab, C.
		Members of the genus Callinectes have a pair of flat rear legs (pereiopods) shaped like oars.
		Callinectes species also have a flat, broad carapace with a series of distinct teeth along the front, around the eyes and terminal spines.

	2006 Young Naturalist Awards - The Effect of Hatchery Cell Size on Growth of Juvenile Blue Crabs, Callinectes sapidus ...
		In response to declining Chesapeake Bay blue crab populations, an effort to better understand the life cycle of the blue crab has been launched in hopes of using the information to create an effective hatchery system to restore the bay's populations.
		One of the single most important questions that must be addressed when developing this type of hatchery system is what impact, if any, cell size has on the growth of juvenile blue crabs.
		With this question in mind, the purpose of this project was to study the impact of cell size on the growth of juvenile blue crabs, Callinectes sapidus Rathbun.

		Callinectes ornatus Ordway, 1863, which is present in the west Atlantic from North Carolina, USA to Rio Grande do Sul, Brazil can be found at depths of up to 75 meters in sand and mud bottoms, as well as in waters with lower salt content (Melo, 1996).
		This was related to the pattern of distribution of the species of the Callinectes and the Penaeus (Williams, 1974 apud Moncada and Gómez, 1980).
		Callinectes ornatus presented a diversified trophic spectrum with a generalized feeding strategy and, therefore, a large niche, which was represented by its successful ingestion of animals of inferior trophic levels.

		Blue crab, Callinectes sapidus, trap selectivity studies: mesh size.
		Catch rates and sizes of blue crabs, Callinectes sapidus, were compared in traps with 2.54 cm (1.0 inch), 3.81 cm (1.5 inches), and 5.08 cm (2.0 inches) square mesh, 2.54 by 5.08 cm rectangular mesh, and 3.81 cm hexagonal mesh.
		The most effective trap to maximize legal catch and minimize sublegal catch was the 3.81 cm hexagonal mesh trap followed by the 5.08 cm square mesh trap.

		Features described for L. callinectes trophonts which are unique for the genus are the fine structure and arrangement of the lorica and lips, the attachment organelle of the peristomial cytoplasm, its attachment to the loricastome walls, and the arrangement of the aboral kinetosomes of the trophont.
		The 4-row terminal peniculus, as revealed by protargol staining, differs from the 6-row terminal peniculus of L. nassa suggesting that the patterns of infundibular structure, as revealed by protargol, should be useful in future taxonomic studies of Lagenophrys species.
		Because the crab is an estuarine species, capable of ranging widely within its habitat, it is subject to the rigors of the euryhaline environment, as well as to the stresses caused by human activity along coastlines.
