Notes 
From other sources
Unreviewed: has not been verified by a taxonomic editorDescription An amphipod with a relatively rounded, broad and robust body (like Urothoe brevicornis). The eyes are very large in males and contiguous on top of the head. The eyes of females are smaller and oval. The body is reddish in colour. Differs from U. brevicornis in having a much broader fifth pair of legs. [details]

Unreviewed: has not been verified by a taxonomic editorDistribution In both periods Urothoe poseidonis mainly occurred in the near-coastal zone, with the exception of the eastern coastal zone but with the inclusion of the western Flemish Banks. Whereas the species was only found 15 times and with a maximum density of 50 ind./m2 in the 1976-1986 period, the species had a higher distribution frequency and maximum density (750 ind./m2) in the 1994-2001 period. In the latter period the species was mainly found in the western near-coastal zone. [details]

Unreviewed: has not been verified by a taxonomic editorHabitat Urothoe poseidonis occurs in fine-grained sediments and reaches a relative occurrence of at least 20% in sediments with a median grain size ranging from 150 to 300 Ám. The species avoids
muddy sediments (mud content maximum 40%). [details]
