Deficient Spiculation in a New Species of Merlia (Merliida, Demospongiae) from the Balearic Islands

  • J. Vacelet
  • M. J. Uriz


Among living calcified demosponges (Sclerospongiae), the genus Merlia Kirkpatrick 1908, is highly remarkable by the facultative character of the calcareous skeleton which is present in the genotype, M. normani Kirkpatrick 1908, but absent in M. deftciens Vacelet 1980, and in another species described by Hoshino (in press).
