Key facts and history

The species later became known as Leander squilla when more genera were split from Linnaeus' Cancer.[2] In 1897, Mary Jane Rathbun realized that Pierre André Latreille had designated Cancer squilla as the type species for the genus Palaemon in 1810.[2] The resulting nomenclatural confusion was resolved by an ICZN ruling that made Palaemon adspersus the type species of Palaemon.[2] The species is uncommon over most of north-western Europe but supports a significant fishery in the Danish Straits.[3]

In the 1758 and 1761 editions of Systema Naturae, Carl Linnaeus gave this species the name Cancer squilla.[2] Because of that designation, the group previously called Leander was renamed Palaemon, and the former Palaemon was reassigned to Macrobrachium.[2] Lipke Holthuis asked the ICZN in 1958 to set aside the name Cancer squilla, since it had been incorrectly applied to Palaemon elegans.[4] The ICZN accepted the petition, so the oldest valid name for this shrimp became Palaemon adspersus Rathke, 1837.[4]

In Danish waters, P. adspersus is found mainly in Zostera eelgrass habitats.[3]

What the cited sources add

The 1994 book "The brackish-water fauna of northwestern Europe" documents the species' distribution, salinity tolerance, and association with eelgrass beds in Denmark.[3][5] The 2010 book "Freshwater prawns" contains the taxonomic history details about Linnaeus' original description and the subsequent genus reassignments.[2][6] According to the 1995 "Handbook of the marine fauna of north-west Europe", the species attains a length of up to 70 mm and has a uniform yellowish-grey coloration.[1][7] That same handbook reports that the rostrum's lower edge carries distinctive pigment spots.[1][7]
