The hypothesis has been made that coral reef sponges facilitate the transfer of coral-derived organic matter to their associated detritivores via the production of sponge detritus, as shown in the diagram. Several sponge species are able to convert coral-derived DOM into sponge detritus, [62] [63] and transfer organic matter produced by corals ...
Spongia officinalis, better known as a variety of bath sponge, is a commercially used sea sponge. [2] Individuals grow in large lobes with small openings and are formed by a mesh of primary and secondary fibers. [3] [2] It is light grey to black in color. [3] It is found throughout the Mediterranean Sea up to 100 meters deep on rocky or sandy ...
All three sponge body plans (asconoid, syconoid, and leuconoid) can be found within the class Calcarea. Typically, calcareous sponges are small, measuring less than 10 cm (3.9 in) in height, and drab in colour. However, a few brightly coloured species are also known. Like the Homoscleromorpha, calcareous sponges are exclusively viviparous. [7]
Neofibularia nolitangere is a massive sponge often growing to about 30 centimetres (12 in) wide and 30 centimetres tall but sometimes reaching 1 metre (3 ft 3 in) in width. It has a central cavity or atrium with thick walls.
Callyspongia (Cladochalina) aculeata, commonly known as the branching vase sponge is a species of sea sponge in the family Callyspongiidae. [1] Poriferans are typically characterized by ostia, pores that filter out plankton, with an osculum as the opening which water leaves through, and choanocytes trap food particles.
Chondrocladia lyra, also known as the lyre sponge or harp sponge, is a species of carnivorous deep-sea sponge first discovered off the Californian coast living at depths of 10,800–11,500 feet (3,300–3,500 m) by Welton L. Lee, Henry M Reiswig, William C. Austin, and Lonny Lundsten from the Monterey Bay Aquarium Research Institute (MBARI).
In sexual sea sponge reproduction, gametes are released into the water by male sponges and are absorbed through the inhalant current of the female sponge. Fertilization occurs when the sperm reaches the ovum. The zygote experiences radial holoblastic cleavage and eventually forms free flowing larvae which develop into new sponge. [16]
