Additional informationAnseropoda placenta feeds on benthic crustaceans (amphipods, cumaceans, mysids, crabs and hermit crabs), molluscs and echinoderms. This species has no known predators (Mortensen, 1927) and no other similar shallow water species. It breeds in the summer producing large eggs. The copepod Asterocheres siphonatus has been associated with Anseropoda placenta by Gotto (1993, 2004).
