9 major phyla of kingdom animalia

Phylum Porifera
aka sponges; means animal that contains holes; are sessile feeders stuck to the ground, eating what comes nearthem body symmetry: asymetric eg. yellow tube sponge, Habitat: mainly marine (salt water), Sponges have a porous body wall. The pores or holes allow water to pass through this animal. Floating foodparticles are caught once they are inside the sponge.
Adult sponges are sessile feeders which means these animals are attached to shells or rocks on the ocean floor as they feed.
Shape:asymmetrical which means no definite shape

Phylum Cnidaria
contains cnidocyte or venomous cells that helps collect and transmit sensory information; body symmetry: radial eg. Jellyfishes.
Habitat: marineBody wall: Their body wall is made of 2 cell layers called the ectoderm and endoderm. The ectoderm is the outside layer while the endoderm is found on the inside layer. A jellylike material is foundbetween these 2 layers.
Digestive System: The digestive system is incomplete which means that coelenterates have just one opening to the digestive cavity. This single opening serves as both its mouthand anus.
Symmetry: radial
Specialized Cells: 1.Most coelenterates have tentacles that contain stinging cells that are used for protectionand capturing food. 2. Their bodies contain a nerve networkthat allows movement of the tentacles and
body

Phylum Platyhelminthes
aka flat worms; lacks a coelom and other body cavities; can be found in marine or fresh water; body symmetry: bilateral; eg.Tapeworms
Habitat: fresh and salt water; terrestrial(land)
Body Plan: These animals are given their name because of their flattened bodies. Flatworms have 3 distinct tissue layers called theectoderm, endoderm, and mesoderm or middle layer.
Each layer gives rise to the various organs and systems of this animal.
Digestive System: In free-living species of flatworms the digestive system is...
