Cnidarians in their medusa form typically exhibit a bell-shaped, free-swimming body structure. They have a gelatinous umbrella-like body called the bell, which is equipped with tentacles hanging downwards, containing specialized cells called cnidocytes for capturing prey. The body is radially symmetrical, with a central mouth opening surrounded by the tentacles, and they possess a simple nerve net for coordinating movement. This structure allows them to effectively navigate and capture food in their aquatic environments.
