Hexactinellida | Lyssacinosida
Environment: milieu / climate zone / depth range / distribution range
Sessile; depth range 18 - 2000 m (Ref. 89939). Polar
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Color: white, yellow, or orange. Growth form: varies from large to barrel or vase shaped for adults around 50 cm high; or vase or egg shaped for budding types up to 15 cm high (Ref. 089939).
Deposits spicules on soft substrates, eventually forming hard mats that is important in colonization. Suspension feeder. Photosynthetic diatoms are present within its cells, but role is still unclear. Reproduction is both sexual and asexual (Ref. 089939). Members of the class Hexactinellida are hermaphroditic. Life cycle: The zygote develops into trichimella larva (free-swimming) before settling down on a substrate where it grows into a young sponge (Ref. 833).
