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.
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 ...
Halichondria is a genus of sea sponges belonging to the family Halichondriidae. [1] [2] These are massive, amorphous sponges with clearly separated inner and outer skeletons consisting of bundles of spicules arranged in a seemingly random pattern.
Chondrilla nucula, sometimes called the Caribbean chicken-liver sponge, is a species of sea sponge belonging to the family Chondrillidae. It is an amorphous shaped sponge that grows in flat, sometimes bulbous sheets in benthic communities. It is sometimes found in marginal, stressful systems such as caves.
Xestospongia testudinaria is a species of barrel sponge in the family Petrosiidae. More commonly known as Giant Barrel Sponges, they have the basic structure of a typical sponge. Their body is made of a reticulation of cells aggregate on a siliceous scaffold composed of small spikes called spicules.
Hippospongia communis also known as the honeycomb bath sponge, is a marine sponge in the phylum Porifera. Hippospongia communis is a brown or darker color [ 1 ] and very porous, due to its many oscules , and is commonly found in shallow waters of the Mediterranean .
These sponges are massive or encrusting in form and have a very simple structure with very little variation in spicule form (all spicules tend to be very small). Reproduction is viviparous and the larva is an oval form known as an amphiblastula. This form is usual in calcareous sponges but is less common in other sponges.
