1. Ascon
2. Sycon
3. Rhagon (Leucon)

Having a large cavity in the middle of his body that serves as the intestines in animals a high level. Cavity is called the cavity Gastrovaskuler. Radial symmetry of her body and there is tentacle around his mouth which is used to capture and put food into his body. Vang tentacles equipped Knidoblas cells that contain toxins called sting Nematokis (characteristic of animals hollow).

Body wall consisting of 2 layers of institutions:
1. Þ outer ectoderm
2. Þ part of the endoderm

Between these two layers is a thin layer called Mesoglea. Because the body wall consists of two layers of the animal's body is called Þ Animals Diploblastik Most live in marine Coelenterata except hydra sp. and several other types. Animals that have two body forms namely phase phase phase Polyps and Medusa. Polyp is a phase when the animal is attached to a substrate (not move) while the medusa is the phase when the animal can move freely.

Classes are included in the phylum Coelenterata are:

HYDROZOA Examples of the types of these classes is the Hydra, who lives in fresh water. The tip is located where the mouth is called the Oral end while the base is attached to the end Aboral. How to reproduction in animals is called the vegetative or generative way. Another example is the Obelia.

Most SCYPOZOA life in the form of medusa. Polyp forms only at the level of the larvae. Examples of the types of these classes is Aurelia sp. (ear jellyfish) are often washed up on beaches. Larvae called Planula Þ, then became known as polyps Skifistoma. Skifistoma formed from a called medusa Efira.

ANTHOZOA not have a medusa shape (Þ lifetime polyps). Examples of the types of classes are sea anemones (Cribinopsis fernaldi). Having a simple respirator called Sifonoglifa Þ.
Ctenophore Coelenterata only thing that does not have mematokis.
Þ is called Wormwood Pipih (flat worm) with the features include:
• Body of bilateral symmetry
• Do not have a circulatory system
• Do not have anal
• Do not have a body cavity including Þ

group Triploblastik Aselomata
• Having smoked basil (Sucker)

The nervous system consists of the brain and nerve ganglion, nerves Peripheral nervous Þ Rope Ladder. Some of them have tools Statotista balance.
