By providing a habitat
Early scientists classified sponges as plants because of their stationary nature and lack of obvious sensory organs. It was not until the 18th century that sponges were recognized as animals due to their ability to move, feed, and reproduce like other animals.
Scientists classify sponges based on their body structure, specifically the presence of pores through which water flows for feeding and gas exchange. Additionally, they consider the type of skeleton sponges have, whether it's made of calcium carbonate, silica, or spongin fibers.

Sponges play a role in filtering pollutants from water, which can benefit human health by improving water quality. They also provide habitats for marine organisms, supporting biodiversity and ecosystem resilience. Additionally, some sponges produce compounds with potential medicinal uses, such as antibiotics and anti-inflammatory agents.
Sponges belong to a group of animals that scientists classify as Po-lifer and are among the simplest of animals, lacking tissue and organs. They filter water through the various chambers within it, absorbing nutrients
It's commonly believed that sponges are a group of animals that don't go through the gastrula stage. However, some scientists disagree and believe that sponges do go through gastrulation.
