This small invertebrate measures about two inches in height. It is a type of unusual sea anemone, anchored on the hard reef substrate. The anemones are are a very diverse bunch and since this is not a common species, it is impossible to determine the exact taxonomy, or even the exact genus, from the photo alone . It appears to be what is known as a "tuberculate night anemone", a member of the family Aliciidae. Presently there are nearly 1500 species of scientifically described sea anemones, though this is by no means a conclusive count of the actual number in existence.
