Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Species petrifying, likely to reach thickness a 4 cm, and able to cover almost completely with considerable surfaces. Smoothes of the surface with some rather large osculum. Rubbery consistency and toughness. Coloring varies according to the light intensity, of the white salts with brown dark marbled (Ref. 358).
Body thickness: 4 cm. Depth: As of surface until approximately 30 m of depth (Ref. 358). Biology: Species has neither spicules, nor fibers of spongin; it works out collagen fibers assuming of the functions of skeleton. Coloring of variable sponge according to the light intensity: the paler the intensity is weak, will be the colors. Conversely, subjected to an intense lighting, it will take darker colors. This phenomenon takes place at many animal species; pertaining to other zoological groups; and can be observed on a single individual: it is the case when the higher face; exposed to the light, is strongly colored, while the faces receiving little light remain definitely paler (Ref. 358). Habitat: Not very enlightened sites; dark zones by rock overhangs; cracks and entries of underwater caves; sometimes; although seldom, on funds sandy. As of surface until approximately 30 m of depth (Ref. 358).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the class Demospongiae are hermaphroditic. Life cycle: The zygote develops into parenchymella larva (free-swimming) before settling down on a substrate where it grows into a young sponge.
