It does so through the use of its tentacles, stinging its prey with a potent toxin containing Upl protein which paralyzes them. However, Oxylebius pictus (the painted greenling) and Lebbeus grandimanus (candy stripe shrimp) have the ability to remain among the tentacles without being harmed. Their sting can also be severely painful for humans. Unlike other sea anemone which are mostly sessile Urticina Piscivora has the ability to detach quickly and reposition itself when it feels threatened by a predatory starfish. Since this anemone is unable to actively swim once detached it is deposited elsewhere by the currents. References External links Actiniidae Animals described in 1978
