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).
