Hydroid stage: The colony appears as a collection of pale, straw-colored stems. The stems are often branched, in contrast to the yellow, unbranched stem of the similar tall tubularia. The colonies are usually no more than 6 cm high. Each hydrant is often rose-red and has two circles of tentacles. The inner circle consists of 14-20 white oral tentacles. The outer circle includes approximately 20 tentacles.
Medusa stage: No information.
It seems to prefer current exposed locations with rocks and boulders. It is registered on all depths, down to 100 meters.
This hydroid is widespread in the Northern Atlantic.
Also known as Tubularia larynx.
