Venus Flytrap Anemone (Actinoscyphia sp.)

The Venus Flytrap Anemone resembles the carnivorous plant found on land, with short tentacles surrounding a folded, concave oral disk. They can be found in every ocean basin, attached to a variety of hard substrates on the seafloor, including the OOI infrastructure! These anemones wait for food to drift into their tentacles lined with stinging cells called nematocysts.
There are numerous deep-sea species in the genus Actinoscyphia, and we see various types at the Slope Base site in 2900 meters of water.

A rattail fish (Grenadier) investigates two pressure sensors at 9500 ft water depth at the sedimented Slope Base site. The one in the background has been equilibrating since 2017 on the seafloor. Venus fly-trap like anemones have colonized the cables that allow data to flow to shore in real-time, and a feeding sea star is on the dusty, 2014 sensor. Credit: UW/NSF-OOI/WHOI, V18.
