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.
they curl up
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.
Grantia belong to the class Calcarea, a class of marine sponges characterized by their calcareous (calcium carbonate) spicules. They are filter feeders that are commonly found in shallow coastal waters.

SPonges have no respiratory or excretory organs; these functions are preformed by diffusion.
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.
