Aplysina fistularis consists of one or more yellow tube-like structures that arise from a closed base and are sessile. The sponge has wide oscula and thin walls with ridged surfaces. [3] Each tube is rarely over 30 centimetres (12 in) in clear water but can reach 50 centimetres (20 in) in turbid-zone reefs. Unlike the related species Aplysina ...

Aplysina archeri, also known as a stove-pipe sponge because of its shape, is a species of tube sponge that has long tube-like structures of cylindrical shape. Although they can grow in a single tube, they often grow in large groups of up to 22 tubes. [ 2] A single tube can grow up to 5 feet (1.5 m) high and 3 inches (7.6 cm) thick.
Included are the yellow tube sponge, Aplysina fistularis, the purple vase sponge, Niphates digitalis, the red encrusting sponge, Spirastrella coccinea, and the gray rope sponge, Callyspongia sp. Sponges are similar to other animals in that they are multicellular , heterotrophic , lack cell walls and produce sperm cells .
Aplysina insularis is a large sponge and consists of one or more cylindrical tubes united at the base. Each one narrows at the apex into a large osculum and this may be surrounded by small, finger-like projections. Slender tendrils and larger rope-like projections may also occur, and in areas with high levels of sedimentation, these may exceed ...
Red volcano sponge (Acarnus erithacus, Poecilosclerida). Spermatocytes develop from the transformation of choanocytes and oocytes arise from archeocytes . Repeated cleavage of the zygote egg takes place in the mesohyl and forms a parenchymella larva with a mass of larger internal cells surrounded by small, externally flagellated cells.
