Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.



Allomelita pellucida, is a small (up to 6 mm) intertidal species, found in the Northern Atlantic. The body of Allomelita pellucida is laterally compressed, as is typical for amphipods, and the head lacks a rostrum, the gnathopods are subchelate, the second pair being much larger than the first. The urosome dorsal posterior margin lacks spines and the telson is cleft.

Recorded distribution in Britain and Ireland

A sparsely recorded species, Allomelita pellucida, is widespread around the British Isles including the St Andrew's Bay, Cullercoats, Hampshire, Southern Ireland and Isle of Man.

Global distribution

Found in the northern Artlantic from Portugal to Norway.


Allomelita pellucida is an intertidal species which can be found in brackish waters usually living as a part of interstitial or epibenthic communities of soft sediments.

Depth range


Identifying features

  • Head without rostrum.
  • Second gnathopod larger than first, especially in males, subchelate.
