Kingdom Animmalia By Kendall Reyes Diana Ramirez Itcelia Segoviano

Porifera They feed through pores on their outer walls. Porifera are unidirectional driven by flagella. They have cellular level organization – Different cells perform different functions. They are both asexual and sexual. Their skeleton is made up of collegen and spicules. Porifera are known as Sponges.

Porifera Their bodies are hollow and they are made up of a jelly-like substance. Their body structure of a sponge is asymmetrical. Dividing into three layers: – The outermost layer is formed from epidermal cells. To average out, a sponge with a 10 cm body can filter at least 100 liters of water everyday.

Cnidaria

Class Turbellaria The majority of the 4,500 species in this class live in the ocean. The most familiar turbellaria is the freshwater planarian Dugesia. They have a soft epidermis that is ciliated on the ventral surface and they ‘re free- living. Most are marine, but some are found in fresh water or on land. They eat small animals or dead and decaying material. Food that’s not digested exits through the mouth. The excretory system is composed of flame cells whose cilia removes excess water and nitrogenous bases. Their nervous system contains eye spots that are sensitive to light and pointed lobes that are sensitive to touch. They reproduce both asexually and sexually.

Classes Trematoda and Monogenea They both consist of parasitic flukes: leaf-shaped flatworms that parasitize mammals. Trematoda is parasitic and is leaf-shaped. They have a thick cuticle to prevent digestion from the host. Nervous/Muscular systems are mostly absent. They produce 1,000’s of eggs because many die.

Class Cestoda About 5,000 species of tapeworms exist in this class. Tapeworms are parasitic. They live in mammals and elk. Excretory, muscular and nervous systems may be absent. Nutrients enter by diffusion.

Phylum: Rotifera (Rotifers)

Class Seisonidea

Class Bdelloida

Class Monogononta

Phylum: Mollusca (Mollusks) There are more than 112,000 species. Mollusks comes from the Latin molluscus, meaning “soft.” Some are fast-moving predators with complex nervous systems. They are coelomates. Most mollusks go through a larval stage called a trochopore. Their body is divided in two main regions: the head-foot and the visceral mass.
