| 説明 | Haliclona rubens (Pallas, 1766) - red sponge on shallow subtidal seafloor.This species has also been referred to as Haliclona compressa and Amphimedon compressa.Sponges are parazoan animals (Kingdom Animalia, Phylum Porifera) - they lack tissues and are essentially well organized colonies of cells. They construct skeletons generally composed of organic or calcareous or siliceous spicules. Sponges are sessile, benthic, filter feeders. They draw in water through small openings (ostia) in the walls of the skeleton and filter the water for tiny particles of food. Filtered water is expelled from a large opening (osculum) or openings (oscula) at the top of the skeleton.Classification: Animalia, Parazoa, Porifera, Demospongea, Haplosclerida, ChalinidaeLocality: just offshore from Bamboo Point, northern Fernandez Bay, western margin of San Salvador Island, eastern Bahamas |
