Hydrozoans from Mauritanian deep waters

During the four Maurit surveys carried out annually from 2007 to 2010, 342 trawl stations were sampled off the Mauritanian coast between 80 and 2000-m depth. Hydroids were captured at 174 stations, totalling 6169 colonies belonging to 63 species and 19 families . Most of the species were Leptothecat...
