Tubularia indivisa are sometimes called Oaten Pipe Hydroids in older reference books. They are annual animals that settle out of the plankton in early Spring and establish themselves on hard surfaces. They rapidly form into flexible stalks about 10/15cms tall, culminating in a flower-like head with fine, fringing tentacles. Plankton sticks to these and the animal feeds on it. Common all around our coasts.
