Individuals used to supply the trade are sourced entirely from the wild, severely depleting local populations in some areas of the Indo-Pacific. Very little is known about the sexual reproductive biology of host sea anemones, precluding their culture in aquaria. Here, we present the first scientific report of broadcast spawning in two species of host sea anemone, Entacmaea quadricolor and Heteractis crispa .

Male and female anemones of both species, collected from the Solitary Islands Marine Park (29°55′S, 153°23′E), Australia, were observed to synchronously spawn gametes into the water column for external development. E. quadricolor spawned on the second and third nights after the full moon (NAFM) in March 2003, and the first NAFM in March 2004. On 10 April 2004, E. quadricolor larvae were detected in ...
