A hydra is a carnivore. It primarily feeds on small aquatic prey, such as tiny fish, zooplankton, and other small invertebrates, which it captures using its specialized stinging cells called nematocysts. These cells help the hydra immobilize and digest its prey.
The hydra has radial symmetry. The hydra belongs to the phylum Cnidaria and many immobile species in this phylum exhibit radial symmetry. Some marine animals that have bilateral symmetry are fish, sea turtles, and marine mammals.
