Group Behavior
Jellyfish do not display segmentation. They have a simple, non-segmented body structure compared to other animals like earthworms or insects.
All cnidarians have on their tentacles stinging cells called nematocytes. They have no brains or a central nervous system. Another common feature is that they all can regenerate, letting them produce asexually (without the need for another partner) and to recover from injury.
This is straight from www.thefreedictionary.com, so I get no credit at all:"Any of various invertebrate animals of the phylum Cnidaria, characterized by a radially symmetrical body with a saclike internal cavity, and including the jellyfishes, hydras, sea anemones, and corals. Also called coelenterate."
A reflex is an automatic response to a stimulus. Humans use reflex actions in only some of their behaviour, for example controlling the eye's pupil size. Simple reflexes. Simple reflexes produce rapid involuntary responses to a stimulus.

instinctive behavior
The most common form of behavior in simple animals, such as cnidarians and worms, is largely driven by basic survival instincts, including feeding, locomotion, and reproduction. Cnidarians, like jellyfish and sea anemones, typically exhibit simple behaviors such as drifting with currents or using their tentacles to capture prey. Worms, on the other hand, often display behaviors like burrowing and crawling to find food or mates. Overall, these behaviors are instinctual and geared towards survival and reproduction in their environments.

All animals respire, but some simple animals, such as cnidarians (anemones, jellyfish, and relatives), and sponges don't have blood.

Cnidarians belong to the Kingdom Animalia. They are characterized by their radial symmetry, tentacles with stinging cells called cnidocytes, and a simple nerve net.

Cnidarians have a simple body plan with a sac-like structure composed of three layers of cells: the epidermis, the gastrodermis, and the mesoglea. They possess specialized cells called cnidocytes that contain stinging structures called nematocysts, used for defense and capturing prey. Cnidarians also have a simple nerve net for coordinating movements and responses.
