Phytoplankton, macroalgal spores, detritus, and bacteria. REPRODUCTIVE BIOLOGY
Reproduction is by protogynous hermaphroditism. The developmental mechanism is lecithotrophic viviparity (no care). Bugula species are placental ovicell brooders, producing small embryos that are brooded in conspicuous hyperstomial ovicells. The size of embryos increases considerably during development owing to nutrition derived from the inside of the ovicell, which functions as a placenta.
CONSERVATION STATUS Not listed by the IUCN.
