Anseropoda placenta, also called the goose foot starfish,[2] is a species of sea star in the family Asterinidae.

It's a very thin, leaflike, flat sea star with short webbed arms.

The aboral surface (top) has a texture of small plates; it is white with five radiating red lines, one down the centre of each arm.

[4] Most common in the Irish Sea and English Channel, and is more rarely found off Scotland.

[5] It is in rapid decline in Northern Ireland due to bottom fishing.
