A calcareous sponge is any of a variety of sponge of the class Calcarea, with skeletons composed of spicules of calcium carbonate.

Coral reefs are formed by the accumulation of calcareous skeletons secreted by corals. These structures provide wave resistance and create diverse habitats for marine life.
Calcareous oozes form when the calcium carbonate shells and skeletons of marine organisms, such as foraminifera and coccolithophores, accumulate on the ocean floor. Over time, these calcareous remains compact and cement together to form a sediment known as calcareous ooze.
importance of coelenterates
Yes, coelenterates are invertebrates.
Crops that can be grown in calcareous soil include wheat, barley, grapes, olives, almonds, and certain types of vegetables like spinach and lettuce. Calcareous soil is rich in calcium carbonate, which can affect the availability of certain nutrients to plants, so it's important to select crops that can tolerate or benefit from these conditions.
harmful effects of coelenterates
Its when a sea animal forms a skeleton from calcium carbonate (CaCO3). Calcium carbonate is dissolved in seawater, but less soluable at higher temperatures. The majority of animals with calcareous skeletons, such as corals, are found in the tropics where it takes less energy to get it out of the seawater
A coelenterates habitat is in the ocean and if it is not it lives somewhere
Calcareous epidermal spicules are small, needle-like structures made of calcium carbonate that are found in the epidermis of certain marine invertebrates such as sponges. They provide structural support and protection to the organism.
