 "Lebrunia neglecta" is an unusual sea anemone in that its tentacles are almost hidden by the ring of six much branching large frond-like pseudotentacles that grow up from the rim of the oral disc.These are some shade of pale or darker brown and have densely branched tips.Below these, on the side of the frond are small, whitish spherical vesicles containing nematocysts that are powerful enough to sting a human.
