Spawning habitat selection by the common cuttlefish Sepia officinalis in the Cí...
Guerra, Ángel; Hernández-Urcera, Jorge; Garci, Manuel E.; Sestelo, Marta; Regueira, Marcos; Gilcoto, Miguel; González, Ángel F.We evaluated specific habitat features (bottom substrate type, depth, temperature, season and latitude- longitude) at random locations in the Cíes Islands (Galician Atlantic Islands National Park, Northwest Spain) to determine their impact on Sepia officinalis spawning habitat use. We performed underwater visual transects via scuba diving. In total, 94 transects were conducted between April 30, 2012 and July 17...
