👉 The tent fluid, also known as the tentacle fluid or hydrostatic fluid, is a specialized liquid found in the soft-bodied marine animals called hydroids and certain species of cnidarians, including some jellyfish. It serves as a critical component in the animal's locomotion and feeding mechanisms, acting as a lubricant to reduce friction between tentacles during movement. Additionally, the fluid helps maintain the structural integrity of the tentacles and aids in the efficient capture and manipulation of prey. The fluid is produced by specialized cells within the animal's body and is pumped through a network of canals, allowing for precise control over tentacle movement and function.
