Ambush Sea Star

Stegnaster inflatus

Stegnaster inflatus is a sea star found exclusively in New Zealand. This species typically inhabits the benthic zone, residing at depths ranging from 0 to 50 meters, with most occurrences recorded shallower than 40 meters. The Ambush Sea Star is characterized by its unique morphology, which features stubby arms that distinguish it from other sea stars in its habitat. Its coloration and texture may vary, but it generally blends well with its surroundings, aiding in its ambush predation strategy. This sea star primarily feeds on small invertebrates, utilizing its ability to camouflage itself within the substrate. The Ambush Sea Star exhibits a reproductive strategy that includes both sexual and asexual reproduction. Embryos develop into planktonic larvae before metamorphosing into juvenile sea stars, which then grow into adults. Encounters with this species during dives can be interesting, as divers may observe its slow movements and unique feeding behaviors. Currently, the conservation status of Stegnaster inflatus is not evaluated, indicating that there is insufficient data to assess its population trends. However, divers should take care not to disturb these creatures, as they play a role in the marine ecosystem of New Zealand's waters.
