Sponges are aquatic animals.
Sponges are a class of aquatic animals that lack vertebrae. Also called poriferans , spongiaria usually live in the sea, grouped in colonies that settle on things that are submerged.
Most sponges – a term that comes from the Latin spongĭa – are tube or sac-shaped, with a single opening. The body has a reinforced wall, either by calcareous, skeletal or siliceous fragments, or by highly resistant fibers that intersect. Sponges feed on small organic particles that they ingest along with the water that passes through various ducts present in this wall.
Characteristics of sponges
Of the thousands of species that inhabit the entire planet, it is estimated that only about 150 sponges are found in fresh water . It is possible to organize sponges into three different levels: leuconoid sponges (of great complexity and with multiple chambers that vibrate), asconoids (which have a central deposit known as atrium or spongiocoel ) and syconoids (which have a thicker wall). than the asconoids).
Among the most particular characteristics of sponges, it should be noted that the majority of their cells have the ability to change into another cell type according to their needs, which is why they are classified as totipotent .
