... species Voluta ebraea Linnaeus, 1758 is an endemic gastropod mollusk from the northern and northeastern seas of Brazil. It is distributed from Pará to Bahia States (Clench & Turner 1964, Matthews 1969, Rios 2009 and has a robust shell (Fig. 1A), up to 200 mm long. Voluta ebraea exhibits a carnivorous diet, preying on mollusks such as bivalves (Dias 2009) and other gastropods ( Mota et al. 2004). This species is known to lay egg capsules only on the calcareous green algae Udotea occidentalis (Fig. 1B), usually one capsule per algae (18.2 2.63 mm in diameter) (Matthews-Cascon ...

This species is known to lay egg capsules only on the calcareous green algae Udotea occidentalis (Fig. 1B), usually one capsule per algae (18.2 2.63 mm in diameter) (Matthews-Cascon et al. 2010). In average, three juveniles hatch per capsule, each with a shell length of 7.8 mm (Matthews-Cascon et al. 2010, Matthews-Cascon et al. 2011). Here, the occurrence of V. ebraea spawning in different substrate types is ...
