Observed Characteristics:

Sample Locations:

Oscarella 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.
