distribution
Distribution and Ecology. Sphyrapus malleolus is widely distributed in the East Atlantic ocean, from the Rockall Plateau to the Angola Basin, including off Greenland, the Bay of Biscay and off Portugal (Băcescu 1985; Bamber 2000; Holdich & Jones 1983 a, b; Larsen et al. 2006; Norman & Stebbing 1886; Sieg 1983). The depth range is 199 to 3061 m (Błażewicz-Paszkowycz et al., 2011). In the GoC, it shows a ubiquitous distribution, and has been found throughout the Gulf on both Iberian and Moroccan margin, as well as in the Deep Field. In Kidd and Meknès MVs, S. malleolus was found on the crater, flank and adjacent sites. The maximum density was found at the crater of Meknès MV, with 170 individuals. m - 2. In sites where vertical stratification was investigated, the species reached 5 – 10 cm depth.
