DIET IN THE WILD: Invertebrates, shrimp and small fishes. U. piscivora have no zooxanthellae and depend wholly on capturing their food, a strategy aided by their exceptionally virulent nematocysts (stinging cells), which can cause long-lasting lesions on humans. Food items are usually swept into the central mouth by the tentacles where enzymes digest the food. Non digested items are expelled out through the mouth.

REMARKS: One fish species, the painted greenling (Oxylebius pictus), has been observed lying unharmed in this anemone much as clownfish do in tropical anemones.
