“…Gibson, 1972;Milton, 1983;Almada, 1999, 2001), and there have been attempts to access possible resource partitioning among them (e.g. Milton, 1983;O'Farrell and Fives, 1990;Faria and Almada, 2001). This resource partitioning may be expressed in trophic differences; however, it seems also to be expressed through differences in ontogeny: L. pholis grows faster and reaches a larger size than C. galerita, which leads the two species to use different types of shelter and prey (Milton, 1983;Faria and Almada, 2001;Monteiro et al, 2005).…”
