Platorchestia platensis is a species of sand flea, an amphipod crustacean that lives on beaches.[2]
Ecology
In common with other sand fleas of the family Talitridae, P. platensis lives above the littoral zone in moist sand or rotting seaweed.[2] There appears to be competitive exclusion between P. platensis and the native Orchestia gammarellus on European beaches.[2]
Distribution
The native range of P. platensis is not known in detail,[2] but it is probably circumtropical.[3] The species description was based on specimens collected near the commercial port of Montevideo, and the species probably spreads through ship's ballast.[2] It was first discovered in northern Europe in 1860 on a beach near Humlebæk, Denmark .[2] By the 1940s, it was common on both sides of the Kattegat; it reached the Netherlands around 1950, and the United Kingdom in 1978.[2]
Taxonomy
Platorchestia platensis was originally described as Orchestia platensis by Henrik Nikolai Krøyer in 1845, based on type material from the Río de la Plata in Uruguay.[2]
