The basal disk of a hydra is located at its base, serving as the attachment point to the substrate or surface it inhabits. This disc-shaped structure allows the hydra to anchor itself securely, enabling it to remain stationary while feeding and interacting with its environment. The basal disk also plays a role in locomotion, as the hydra can use it to glide or move by contracting and expanding.

Small buds called basal discs are released from the base of a hydra to detach and move to another area. Basal discs allow hydra to reproduce asexually and establish new colonies in advantageous locations.
The basal disc in a hydra serves as an anchor, allowing the organism to attach itself to substrates like rocks or plants in its aquatic environment. This structure is crucial for stability and helps the hydra maintain its position while feeding and performing other activities. Additionally, the basal disc contains specialized cells that aid in attachment and can also play a role in regeneration.
Basal implies located at or near the base of a plant's stem. So a basal shoot, for example, is one that sprouts from near or at the base of a plant's stem.
