Observed Characteristics:


  • brown


  • branching


  • soft

Sample Locations:

  • Bahamas

Haliclona (Reniera) ?ruetzleri

Notes: Thin, sprawling, brown, soft branches. The ectosome has an unispicular tangential reticulation with additional erect spicules at the nodes. Choanosomal reticulation a bit more paucispicular. Spicules oxea 90-100 by 7.5-10 µm. Bahamas material lacks microscleres (two categories of sigma, toxa), hence the tentative identification pending further comparisons. It should also be compared to Haliclona (Re.) chlorilla Bispo, Correia & Hajdu, 2014 from Brazil, that also lacks microscleres.
