Hydra feeds on different aquatic small animals like Daphnia and Cyclops.
It has tentacles with stinging cells on it for this purpose. Stinging cells called cnidoblasts are scattered on the outer layer of the tentacles.
Each cnidoblast has a small capsule that contains tiny hollow thread that acts as food catching apparatus.
From the cnidoblast small trigger projects out called cnidocil.
