Occurrence of Chaceon Affinis (Decapoda: Geryonidae) in the Vicinity of a Hydrothermal Vent Site on the Mid-Atlantic Ridge

Egg development and fecundity estimation in deep-sea red crab, Chaceon affinis (Geryonidae), off the Canary Islands (NE Atlantic)

“…This last species inhabits the eastern Atlantic Ocean (64 • N-15 • N) from Iceland to Senegal, including the Azores, Madeira, and the Canary and Cape Verde Islands between 130 and 2047 m depth (Kjenerud, 1967;Samuelsen, 1975;Manning and Holthuis, 1981;Sánchez and Olaso, 1985;Dawson and Webber, 1991), and also know from the Mid-Atlantic Ridges i.e., Menez Gwen, Lost City (Biscoito and Saldanha, 2000;Biscoito, 2006). In the Canary Islands, several studies demonstrated the relative abundance of this species at depths between 600 and 1000 m (López Abellán et al, 1994;González, 1995) and some biological aspects (reproduction, sizes at maturity, population structure) have been studied (Fernández-Vergaz et al, 2000;López Abellán et al, 2002).…”
