(de Laubenfels,1926) |
Sponge:
Concave-convex lamellate 1 cm thick; 12 cm in diameter.
Consistency: firm, brittle.
Surface: superficially smooth.
Oscula: on concave side only, circular or oval, 0.7 - 1.1 mm in diameter.
Color: Pres: Pale drab.
Spicules: Megascleres:
(1) Oxeas:
340 - 460 um.
x 19 - 25 um.
Microscleres:
(1) Sigmas C-shaped with sharply recurved apices:
50 - 123 um.
Skeleton:
Ectosome: Detachable, optically evident confused tangential reticulation of large spicules; the polygonal meshes 0.5 - 0.8 mm in diameter.
Choanosome is a somewhat confused isodictyal reticulation with spongin nodes, but with tracts showing a tendency to form rounded meshes.
Distribution: Southern to Central California.
Depth: Deep water, 720 m.
Note: Designated as Haliclona (Gellius) textapatina in the Systema (De Weerdt, 2002). However recent review places it in Xestospongia. Was Sigmadocia.
