Occurrence of Savalia savaglia (Anthozoa: Zoantharia) in the Ría de Arousa (Galicia, north-western Spain, north-eastern Atlantic)

Abstract

Savalia savaglia (Anthozoa: Zoantharia) is an uncommon, large, arborescent, modular species best known from the western basin of the Mediterranean Sea, and recorded recently from the Canary Islands. During dives in the Ria de Arousa (Galicia, north-western Spain, north-eastern Atlantic), four colonies were seen at a depth of 26–29 m, and identified by morphological study, including the cnidome, and DNA sequencing. These new records extend considerably the distribution of the species. Given that S. savaglia lives in the north-west of the Iberian Peninsula, overlooked old records from the literature further north from the Bay of Biscay may be reliable.
