Tubularia indivisa is a large hydroid reaching 10 to 15 cm in height. Living in small clumps, the unbranched stems, gathered at the base, are pale horn coloured and bear a single pale pink polyp. The tentacles form two concentric circles: those of the external circles are longer than those of the oral one. In Spring (mostly), reddish-pink gonothecae grow between the tentacles. There is no medusa released. It lives attached to rocks, or sometimes among seaweeds' haptera in current-swept areas.
Tubularia indivisa lives in the North-East Atlantic Ocean, the English Channel, the North Sea and the Norwegian Sea.
