No they do not
Yes, the brain of a hydra is a part of its nervous system. Hydras have a simple nerve net instead of a centralized brain, which helps them coordinate their movements and responses to stimuli.
Some animals, such as those in the genus Hydra, don't actually have a brain per se, making it difficult to answer.

The main difference between Hydra 10 and Hydra 20 is their capacity. Hydra 10 has a capacity for 10 gallons, while Hydra 20 has a capacity for 20 gallons. This means Hydra 20 can filter a larger volume of water compared to Hydra 10.
The nervous system of a hydra is decentralized and consists of a simple nerve net without a central brain, allowing for basic reflexive movements and responses to stimuli. In contrast, a grasshopper has a more complex, centralized nervous system featuring a brain and a ventral nerve cord with ganglia, enabling more coordinated movements and advanced behaviors. This difference reflects their varied lifestyles, with the hydra being a simple aquatic organism and the grasshopper being a more mobile terrestrial insect. Overall, the structural complexity of the grasshopper's nervous system supports greater behavioral versatility compared to the hydra.
