Clark & A.M. Clark (1967); Domenico et al . (2009). Occurrence: Northeast Atlantic and Mediterranean Sea, from Morocco to west of Sierra Leone and Liberia, including the Azores, Madeira and Canaries (A.H. Clark & A.M. Clark 1967); the subspecies A. bifida bifida (Pennant, 1777) is distributed further north in the Northeast Atlantic, from Portugal northwards to the British Islands (A.H. Clark & A.M. Clark 1967). Depth: 0–200 m (A.H. Clark & A.M. Clark 1967); AZO: 3–60 (?130) m (Koehler 1898, Marques 1983). Habitat: present in waters with strong tidal currents and related upwelling phenomena (Domenico et al . 2009); in shallow waters, it lives in relatively protected areas, clinging to rocks, algae or other sessile fauna (Mortensen 1927a, Nichols 1994, Morton et al . 1998). Larval stage: the females Antedon bifida brood the eggs, which produced a doliolaria larvae (non-feeding pelagic larvae, c. 5 days; Lahaye & Jangoux 1988; Nichols 1994).
