What are the feautures of a coelentrate?

Answer 1

Coelenterates, also known as cnidarians, possess several key features, including a simple body structure with a central cavity called the gastrovascular cavity, which serves for digestion and circulation. They exhibit radial symmetry and have specialized cells called cnidocytes that contain stinging structures called nematocysts for capturing prey and defense. Coelenterates can exist in two main forms: the sessile polyp and the free-swimming medusa. Additionally, they have a simple nerve net, allowing for basic movement and response to stimuli.
