Why are sponges found in aquatic?

Sponges are primarily found in aquatic environments because they rely on water for their feeding, respiration, and waste removal processes. Their porous bodies allow water to flow through, enabling them to filter out nutrients and oxygen from the water. Additionally, aquatic habitats provide the necessary buoyancy and stability that sponges need for attachment and growth. While some sponges can tolerate brackish or freshwater, most thrive in marine ecosystems.
