Distribution

Eudendrium ramosum is considered as a cosmopolitan species by Bouillon et al. (2006), but many records are likely doubtful ( Ramil & Vervoort 1992; Marques et al. 2000). Schuchert (2012) indicated that all records outside the East Atlantic (Arctic to South Africa, including the Mediterranean) need confirmation. The bathymetrical distribution of the species extends from intertidal areas ( Ansín Agís 1992) to a depth of 1870 m ( Ramil & Vervoort 1992).
