Observed Characteristics:

  • encrusting
  • fan


  • soft

Sample Locations:

  • Bahamas

Plakina nathaliae

Notes: Extremely soft sheets, cream in color, semitransparent, inhabiting deep reef cave walls and overhangs. The sponge is only partly attached to the substratum, so that the edges are free. It is extremely difficult to collect as it virtually disintegrates upon handling. No spicules. It has also been pictured in Colin (1978) Caribbean reef invertebrate guide as Halisarca sp. It was originally described under genus Halisarca (name used in the third edition of this guide), but it was later changed to the genus Plakina following the revision by Ruiz et al. (2017).
