Oscarella sp.-cream veil |

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. |

Slightly tough to softer, creamy-orangy encrustations growing on deep reef overhangs, with characteristic brain-like convolutions and scattered oscules on skin lobes. Spicules are diods and triods with a few spines, calthrops and small branched lophocalthrops (lophotriaenes). Softer specimens have less spicules than tougher ones, often just a few. Should be compared to Plakina versatilis (Schmidt, 1880) (originally described under Corcitium, see Rützler et l., 2009). |
