The basal disc is a specialized structure found in certain organisms, such as sea anemones and jellyfish. It serves as the attachment point that anchors these creatures to surfaces like rocks or coral. The basal disc is typically flat and allows the organism to remain stable in its environment. In sea anemones, the basal disc is covered with a sticky substance that helps it adhere to substrates. This feature is crucial for their survival, as it prevents them from being swept away by currents. The basal disc also plays a role in the organism's ability to capture prey and interact with its surroundings.
