The first record of this crab outside its native range [13] [14] [15] was from Townsends Inlet, Cape May County, New Jersey (between Avalon and Sea Isle City) in 1988. [ 2 ] [ 16 ] The larvae are thought to have been transported via the fouled hulls of yachts. [ 8 ]
Potamon fluviatile is a freshwater crab found in or near wooded streams, rivers and lakes in Southern Europe.It is an omnivore with broad ecological tolerances, and adults typically reach 50 mm (2 in) in size during their 10–12 year lifespan.
Libinia emarginata is roughly triangular in outline and very heavily calcified, with a carapace about 4 in (100 mm) long and a leg span of 12 inches (300 mm). [4] The whole crab is khaki, and the carapace is covered in spines and tubercles, [5] and, as with other decorator crabs, often clothes itself in debris and small invertebrates.
Nearly 1 million crabs are harvested yearly for bait in the United States, dwarfing the biomedical mortality. [59] However, fishing with horseshoe crab was banned indefinitely in New Jersey in 2008 with a moratorium on harvesting to protect the red knot, a shorebird that eats the crabs' eggs. [59]

[5] [6] Size at gonadal maturity is greater for populations at higher latitudes. [5] A study in Rhode Island Sound found a discrete molting season in June for smaller (carapace width less than 4.7 in (120 mm)) male Jonah crabs. With each successive molt, post-molt width increments decreased for female crabs and increased for male crabs.
