Walking Anemone

The Walking Anemone, (Preactis millardae), also known as the Hedgehog Anemone or the Sock Anemone, is a species of sea anemone found on both sides of the Cape Peninsula in South Africa, where it is endemic. It is typically found 33 to 99 feet below sea level. It is the only member of its genus.

This is an unusual looking anemone, growing up to 12 inches long, and being 2.4 inches in diameter. It has papillae (nipple-like projections) covering its whole body column. Scarlet lines radiate outward from the mouth and can be seen on the body between papillae. The background color of the body is pale. Juveniles are pale or white in color and have protruding rounded swellings on their bodies instead of papillae.

The Walking Anemone moves similar to that of a leech, creeping along its habitat, usually vertical rock walls. It can sometimes be found on sand patches as well. This ravenous predator feeds mainly on the multi-colored sea fan. It is often found eating these animals, consuming them down to the skeletal support.
