Psalidopus is agenus ofshrimp placed in its own family,Psalidopodidae, and superfamily,Psalidopodoidea.[1] It comprises three species, one in the westernAtlantic Ocean, and two in theIndo-Pacific.[2][3]
Psalidopus barbouri occurs on continental and insular slopes fromFlorida, theBahamas and theGulf of Mexico, to parts of theCaribbean Sea, perhaps extending as far south asSuriname.[2]P. barbouri lives on steeply sloping soft muddy bottoms, sometimes mixed with sand, at depths of 400–800 m, where the temperature ranges from 6.1 to 10.0 °C (43.0 to 50.0 °F).[2] Adults have acarapace length of 13–32 millimetres (0.51–1.26 in), with the total length of the animal, from the tip of therostrum to the tip of the tail, being up to 5.5 times longer than the carapace.[2]
Psalidopus huxleyi occurs on continental and insular slopes across theIndian Ocean, including theLaccadive Sea, off southernIndia, theAndaman Sea and theTimor Sea, as well as in the westernPacific Ocean from southernJapan to thePhilippines, theSulu Sea, and theCelebes Sea.[2]P. huxleyi lives on steeply sloping bottoms of various compositions and consistencies, at depths of 500–100 m, where the temperature ranges from 5.9 to 13.6 °C (42.6 to 56.5 °F).[2] Thecarapace is 10–30 mm (0.39–1.18 in) long.[2]
Psalidopus tosaensis lives at greater depth (c. 2800 m) and lower temperature – 1.6 °C (34.9 °F) – than either of the other species ofPsalidopus.[3] Although it is geographically closer toP. huxleyi, it appears to be more closely related toP. barbouri.[3]
