Why are sponges considered animals?
Also known as Poriferans, sponges are given structure by a skeleton-like framework composed of various organic and inorganic materials, including spicules made out of silica or calcium carbonate. This framework, which is lined with flagellated cells, creates a network of pores, channels, and chambers within the sponge.

What are the different types of sponges?
They are classified into three groups: 1 Calcareous: These sponges have their spicules made of calcium carbonate and do not have sponge fibers. They are usually small and pale in color. 2 Hexactinellids: Also known as silica sponges, they have silica spicules and their appearance is glassy. They are animals from warm seas, and they live in considerable depths. 3 Demosponges: They behave like sponges without spicules such as bath sponge or kitchen sponge, which maintain their shape thanks to sponge fibers, a protein close to silk. This is the type in which most sponges are found. They are usually bright colors such as red, green, and blue because of the granules found on the inside of the sponge cells.
How do porifera reproduce?
The reproduction of porifera can be achieved in two different ways: asexually, by germination from the fragmentation of their own organism, thus giving birth to a new organism; and sexually through the expulsion of eggs in the water.
Why are sponges not considered animals?
For a long time sponges were not regarded to be animals, exactly because of their non- animal-like appearance; they are sessile and do not possess the ability to catch the food or getting rid of their wastes and exhibit more or less no response to stimuli.

The vast majority of sponges, however, possess a true skeleton called auto skeleton composed of elements secreted by the sponge itself.

Summary
Ecology
Sponges are worldwide in their distribution, living in a wide range of ocean habitats, from the polar regions to the tropics. Most live in quiet, clear waters, because sediment stirred up by waves or currents would block their pores, making it difficult for them to feed and breathe. The greatest numbers of sponges are usually found on firm surfaces such as rocks, but some sponges …
Etymology
The term sponge derives from the Ancient Greek word σπόγγος (spóngos 'sponge').
Overview
Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells. Unlike other animals, they lack true tissues and organs. Some of them are radially symmetrical, but most are asymmetrical. The shapes of their bodies are adapted for maximal efficiency of water flow through the central cavity, where the water deposits nutrients and t…
Distinguishing features
Sponges constitute the phylum Porifera, and have been defined as sessile metazoans (multicelled immobile animals) that have water intake and outlet openings connected by chambers lined with choanocytes, cells with whip-like flagella. However, a few carnivorous sponges have lost these water flow systems and the choanocytes. All known living sponges can remold their bodies, as most types of their cells can move within their bodies and a few can change from one type to an…
Basic structure
A sponge's body is hollow and is held in shape by the mesohyl, a jelly-like substance made mainly of collagen and reinforced by a dense network of fibers also made of collagen. The inner surface is covered with choanocytes, cells with cylindrical or conical collars surrounding one flagellumper choanocyte. The wave-like motion of the whip-like flagella drives water through the sponge's bo…
Vital functions
Although adult sponges are fundamentally sessile animals, some marine and freshwater species can move across the sea bed at speeds of 1–4 mm (0.039–0.157 in) per day, as a result of amoeba-like movements of pinacocytes and other cells. A few species can contract their whole bodies, and many can close their oscula and ostia. Juveniles drift or swim freely, while adults are stati…
Systematics and evolutionary history
Linnaeus, who classified most kinds of sessile animals as belonging to the order Zoophyta in the class Vermes, mistakenly identified the genus Spongia as plants in the order Algae. For a long time thereafter sponges were assigned to a separate subkingdom, Parazoa ("beside the animals"), separate from the Eumetazoa which formed the rest of the kingdom Animalia. They have been reg…
Sponges Characteristics
Sponges Classification
- The classification of porifers is based on the presence or absence of spicules, their composition and shape. They are classified into three groups: 1. Calcareous: These sponges have their spicules made of calcium carbonate and do not have sponge fibers. They are usually small and pale in color. 2. Hexactinellids: Also known as silica sponges, they have silica spicules and their …
Sponges Reproduction
- The reproduction of porifera can be achieved in two different ways: asexually, by germination from the fragmentation of their own organism, thus giving birth to a new organism; and sexuallythrough the expulsion of eggs in the water. In fragmentation, part of the sponge separates from the rest of the body and it regenerates the missing parts, creating a new organism. This is …
Sponges Feeding
- This species has a diet based on microscopic particles, bacteria, protozoa and green algae or cyanobacteria. There may also be some carnivorous species that feed on tiny crustaceans. Due to the particularity of its food, and not having mouths, this species feeds through pores located on the outside of its body, with which they can capture water from their habitat. Water passes throu…
Breathing
- Sponges or porifers have pores on the outside of their bodies, allowing them to feed and breathe by absorbing excessive amounts of water. During the water absorption, sponges obtain oxygen dissolved in it. Sponges have the ability to purify carbon dioxide and ammonia residues, serving as a natural filter to its habitat. From this process, the necessary oxygen to live is obtained. This …
Habitat
- The sponges, being aquatic organisms, live mostly in ocean areas, ranging from the coast to seven thousand meters deep. Approximately 150 species of sponges are naturally freshwater. Due to their motor limitation, since they do not manage to move on their own, but are dragged by water currents, they live stuck to the bottom, just like a plant. Some of these species, when they …
Examples
- Some of the best-known poriferous animals include the family Spongiidae to the popularly called horse sponge. Another example of the Petrossidae family is the barrel sponge.
