a sponge defends its self by using its stinging cells! :)
SPonges have no respiratory or excretory organs; these functions are preformed by diffusion.
Grantia are a type of simple sponge-like animals that belong to the phylum Porifera. They lack true tissues and organs, and their bodies are organized into simple layers of cells surrounding a central cavity. One distinctive feature of grantia is their filter-feeding mechanism, where they draw in water through pores in their bodies to obtain food.
Spicules of Grantia typically have four prongs. These prongs help provide structural support to the sponge's body and also aid in capturing food particles from the water.
What supports a sponge it its agility to love god with all its tentacles, rays, and hole on the bottom of itself.
Grantia compressa was created in 1780.

Grantia, a type of sponge, exhibits radial symmetry. This means that its body can be divided into similar halves by multiple planes that pass through its central axis. This symmetry is characteristic of many simple aquatic organisms, allowing them to efficiently capture food and respond to their environment from any direction.
A sea sponge protect itself by releasing toxic gases.
