There are 2 body forms in Phylum Cnidarian. They are:
Polyp ex: Sea Anemone
Medusa ex: Jellyfish, Portugese Man of War
The two body forms in the phylum Cnidarian are the polyp and medusa. Polyps are usually stationary, with a cylindrical body and tentacles surrounding a central mouth. Medusas are free-swimming and have a bell-shaped body with tentacles hanging down.
sea anemone belongs to phylum echinodermata.
Most animals in the Mollusk phylum have bilateral symmetry, where their body can be divided into two equal halves along a single plane. This symmetry allows for more efficient movement and sensory abilities.
The phylum that includes plants with seeds is the Angiosperms (Phylum Anthophyta) and Gymnosperms (Phylum Coniferophyta). These two phyla are characterized by the presence of seeds, which are structures that contain and protect the embryo of the plant.
The phylum Cnidaria has two layers of tissue: the outer epidermis and the inner gastrodermis separated by a jelly-like mesoglea layer. This simple body plan is characteristic of organisms like jellyfish and sea anemones.
Each animal phylum has unique characteristics that distinguish it from others. For example, all chordates possess a notochord at some point in their development, arthropods have jointed appendages and an exoskeleton, mollusks have a muscular foot and a soft body enclosed in a mantle, and echinoderms have a spiny skin and a water vascular system.

sea anemone belongs to phylum echinodermata.
Two classes within the phylum Cniadrian are Anthozoa and Hydrozoa. Two animals in the Phylum Cniadrian are jellyfish and corals.
The basic body symmetry of a cnidarian, especially a jellyfish, is radial, meaning that no matter how it is bisected along its central axis, its two halves will be mirror images of one another.
Cnidarians have simple structure; a blind ended gut, tentacles, a pharynx and several other minor organs, and gonads.
Cnidarians have no gut in their body .The structure which performs function similar to gut is called gastrovascular cavity .
Jellies and sea anemones.

Two other animals in the same phylum as a crayfish are lobsters and shrimp. They all belong to the phylum Arthropoda, which is characterized by having jointed legs and a hard exoskeleton.
Most animals in the Mollusk phylum have bilateral symmetry, where their body can be divided into two equal halves along a single plane. This symmetry allows for more efficient movement and sensory abilities.
The mesoglea is a gel-like substance found between the epidermis and gastrodermis in the body wall of cnidarians. It provides structural support and helps with buoyancy regulation in some species.
The body systems that cnidarians have take two forms. The main body forms are medusa and polyp. Cnidarians do not have a transport system and the body surface is used for gaseous exchange.
