What describes a polyp form of cnidaria?

The polyp form of cnidaria is characterized by its anchored nature and structure. In this form, the organism typically has a tubular body with a mouth located at one end, surrounded by tentacles that are used for feeding and defense. The polyp is attached to a substrate, which distinguishes it from the medusa form, such as jellyfish, which are free-swimming. This anchored position allows polyps to engage in a sessile lifestyle, enabling them to capture passing prey with their tentacles while remaining stationary. The tentacles are lined with specialized stinging cells called nematocysts, crucial for both capturing food and deterring predators.
