Tubularian \Tu`bu*la"ri*an\, n. (Zool.)
   Any hydroid belonging to the suborder Tubularida.
   [1913 Webster]

   Note: These hydroids usually form tufts of delicate tubes,
         and both gonophores and hydranths are naked. The
         gonophores of many of the species become free
         jellyfishes; those of other species remain permanently
         attached as medusoid buds or sporosacs. See Illust.
         under {Gonosome}, and {Cymnoblastea}.
