Sponges play an important role in the benthic fauna throughout temperate, tropical and polar habitats. [13] If there is a high volume of predation it can effect bio erosion , reef creation, multiple habitats, other species and help with the nitrogen levels.
All sponges in this class are strictly marine, and, while they are distributed worldwide, most are found in shallow tropical waters. Like nearly all other sponges, they are sedentary filter feeders. All three sponge body plans (asconoid, syconoid, and leuconoid) can be found within the class Calcarea. Typically, calcareous sponges are small ...
The sponges are inserted into the vagina in much the same way a tampon is, but when full are removed, cleaned, and reused, rather than discarded. The advantages of a reusable tampon alternative include cost-effectiveness and waste reduction. (Since sponges are biodegradable, even when a menstrual sponge's absorbent life is over it can be ...
Sponges are more abundant but less diverse in temperate waters than in tropical waters, possibly because organisms that prey on sponges are more abundant in tropical waters. [48] Glass sponges are the most common in polar waters and in the depths of temperate and tropical seas, as their very porous construction enables them to extract food from ...
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.
All sponges in this class are strictly marine, and, while they are distributed worldwide, most are found in shallow tropical waters. Like nearly all other sponges, they are sedentary filter feeders. Of the 15,000 or so species of Porifera that exist, only 400 of those are calcareans.

The following is a list of types of seafood. Seafood is any form of sea life regarded as food by humans. It prominently includes shellfish, and roe. Shellfish include various species of molluscs, crustaceans, and echinoderms. In most parts of the world, fish are generally not considered seafood even if they are from the sea.
