Food getting and sensory processes in coelenterates?

Coelenterates, such as jellyfish and corals, utilize a simple digestive system and specialized cells called cnidocytes to capture prey. These cells contain nematocysts, which release toxins to immobilize or kill prey. Sensory processes in coelenterates are primarily mediated by a decentralized nerve net, allowing them to respond to environmental stimuli, such as light and touch. This enables them to efficiently locate food and react to threats in their aquatic environments.
