Feeding waysSmall fish stick on tentacles

and knidoblast

the feses is going out through the mouth

the nutrients is spreaded difusially

it absorbs the nutrients

the meal is proceeded using an enzim produced

by gastrodermis

pass through gastrovascuIer

the cell produce pois the prey conscious until the tentacles catch them into the mouth

the cell produce poison

Reproduction of Coelenterata

Vegetative

Vegetative reproduction through the formation of the shoot. If the bud on its body off it will grow into new individuals. Generative

Generative or sexual reproduction occurs with the fusion between male sex cells (sperm) and egg cells (ova) – swimming into the ova – zygot – larva – planula – swimming away from the mother – becoming polyp in the edge of water

HYDROZOA

1. Hydrozoa is genuine from Hydra, it means likely snake

2. Generally, live in group or individual3. Soliter is structured polyp and for those

which are in group structures polyp or medusa

4. Hydrozoa live either in a group or individual

5. The examples of Hydra and Obellia

6. Tentacle serves as a tool to catch food7. Asexual reproduction by forming buds on the side of the body8. Sexually begins with the formation of the ovary and testis9.Above the testicles and ovaries are under10. Food such as small animals and low Crustaceae

Special characteristic feature of obelia1. Live in marine water2. There are polyp and medusa3. Experiencing life in its life cycle rotation4. Obelia polyp phase usually live in colonies

encountered in the life cycle tages of polyp and medusa, but polyp more dominant.

CLASS ANTHOZOA

Derived from the word anthos = flower. Life in marine polyp form, do not have medusa phase. Reproduce asexually by budding, division and fragmentation. Sexsual reproduction by fertilization produces a zygote which then became planula.

1. Hexacorallia

Rose marine life clinging to the bottom of the water. There are many short-sized tentacles, example : Sea anemone (Metridium sp.) Urticina lofotensis, Anthopleura xanthogrammica, and Euphyllia glabrescens

(Anemon Laut) Metridium sp.

• Coral live by colonies which forming a mass that is stiff and strong during polyp. Chalk of dead coral will be order to coral reefs.

• There are three types of coral reefs,namely coral beach, barrier reef, and coral atolls

Cuzoboa included in the class Scyphozoa as Cubomedusa or Carybdeida order on the basis of some of the similarities of anatomy , physiology and life cycle . However , became a class by itself because Cubozoa also have similar characteristics to the Hydrozoa . Ex : Chironex

Benefit Of Coelenterata

1. Cosmetic and food2. As a barrier reefs for protect the

beach from abrasion3. As a hiding and breeding place4. Beach with beautiful coral could

be used as a place for recreation
