20. The Venus Flytrap Anemone (Actinoscyphia aurelia)
The Venus Flytrap Anemone is aptly named for its remarkable resemblance to the terrestrial plant. Unlike most anemones, it can snap shut on unsuspecting prey that drifts too close, making it a fearsome predator in the deep Gulf of Mexico. This rare feeding behavior sets it apart from its relatives and highlights the inventive survival strategies of deep-sea dwellers. Learn more about this captivating anemone at NOAA.
