They made do, but there is no evidence. SORRY! :)
The common name for calcareous sponges is "calcareous sponges" or simply "calcareous sponges." These sponges belong to the class Calcarea and are characterized by their calcium carbonate spicules. They are typically found in marine environments and can vary in shape and size.
Sponges are not plants but animals .
A calcisponge is any of a group of marine sponges containing calcareous spicules - spicules which resemble calcium carbonate.
Spicules in calcareous sponges are primarily composed of calcium carbonate. They serve as structural elements, providing support and rigidity to the sponge's body. The spicules can vary in shape and size, typically appearing as needles or rods, and are formed through a biological process involving the sponge's cellular activity.
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.
Sponges don't have skeletons! They are invertebrates which means the creature doesn't have a backbone, but in this case, it doesn't have a skeleton! (I think this is right, I apologize if it isn't)
The calcareous tubeworm is a marine worm. It is commonly found in the intertidal zone, but may live at depths up to 100 meters.
The three classes of sponge skeletons are siliceous or glass sponges (Class Hexactinellida), calcareous sponges (Class Calcarea), and sponges with a fibrous protein skeleton (Class Demospongiae). Each class has unique structural characteristics that support the sponge's body.
yes sea sponges.
There are thousands of different types of sponges, so there's not enough room to list them all. Here's a great website showing several hundred different sponges found in the Caribbean so you can get some idea of the different groups they fall into.
They live underwater.smart one
Sponges do live in the ocean.
