The tubular hydroid (''Ectopleura crocea'') is a species of hydroid cnidarian, and is found in temperate coastal waters. It is a member of the family Tubulariidae. ==Description== The tubular hydroid resembles a long-stemmed narrow-petalled flower. The stem is encased in a sheath. The polyps are pink or orange and white, with an outer ring of long tentacles. There are short tentacles surrounding the mouth rising from a cluster of yellow bead-like bunches of reproductive sporosacs.〔Branch, G.M., Branch, M.L, Griffiths, C.L. and Beckley, L.E. 2010.
