Orchestia mediterranea, sometimes called the Mediterranean beach hopper,[2] is a species of amphipod in the family Talitridae (sandhoppers).
Description
This species grows to a maximum length of 19 mm (0.75 in) and is pink in colour.[2] It can be distinguished from Orchestia gammarellus by the ramus (branch) of its pleopods (swimming legs), which are as long as, or longer than, the peduncle (base segment of the antenna); in O. gammarellus the ramus of the pleopods is much shorter than the peduncle.[3]
Distribution
Orchestia mediterranea is found in the Mediterranean Sea, Black Sea and the seas around Great Britain and Ireland.[1][4][5]
Behaviour
Infection with the parasite Paramarteilia orchestiae can cause intersexual attributes in male Orchestia mediterranea.[6]
A study in Bizerte found that Orchestia mediterranea was more common in autumn than summer.[7]
