''Lebrunia danae'' is a species of sea anemone in the family Aliciidae. It is found in the Caribbean Sea and Gulf of Mexico. == Description == ''Lebrunia danae'' 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. After contact with a prey item, the pseudotentacles retract and the tentacles, which are also armed with nematocysts, grasp the prey and draw it into the mouth. The column of the anemone is usually invisible, being anchored in a crevice. This species can grow to a diameter of . It is very similar in appearance to the closely related ''Lebrunia coralligens'', but the pseudotentacles of that species are much less branched, and often have swollen, double-lobed tips.〔
