Description, classification, synonyms, distribution map and images of Palaemon elegans. Palaemon elegans, also known as the Rockpool Shrimp or the Rockpool Prawn, inhabits coastal rockpools, shallow rocky areas and man-made structures. Palaemon elegans, a new component of the Gulf of Gdańsk macrozoobenthos, colonised the southern Baltic coastal zone in the late 20th and early 21st century.

In contrast, palaemon elegans of eyestalk removed from animals that had developed a full hyperglycemic palaemon elegans after exposure to low concentrations of Hg, Cd, Pb, or high concentrations of Cu and Zn were depleted of cHH as shown by the attenuation of the response after injection of the extracts into eyestalkless animals.
This generalized and predictable sublethal response can be used as a quantitative physiological biomarker for water quality monitoring assessment.
Is there a reference specimen?: The identification was confirmed from palaemon elegans photograph. Actions taken to date: Habitat Intertidal on rocky shores in rock pools around mid-tide level but sometimes higher.
WoRMS - World Register of Marine Species
Moves offshore palaemon elegans winter in northern latitudes. Chemoreception might play an important role for endemic shrimp that inhabit deep and dark hydrothermal vents to find food sources and to locate active edifices that release specific chemicals.
It has been assessed that each day there are thousand marine species transported worldwide Carlton and Geller, Decapod planctonic larvae are also known to migrate this way Chu palaemon elegans al. Further spread of palaemon elegans species by natural dispersal is suspected in the Baltic Sea to the slightly brackish Gulf of Bothnia.
It is also possible that with ballast waters it will be transferred to coastal palaemon elegans and estuaries of North America or the Far East.
The ratio of the eye diameter and the carapace length is 0. palaemon elegans
Peduncle of first antenna: The distal limit of the lappet is broad and palaemon elegans outer angle extends laterally as a flexible tooth-like projection.
