Kingdom Annimalia

Kingdom AnimmaliaByKendall ReyesDiana Ramirez Itcelia Segoviano

PoriferaThey feed through pores on their outer walls.Porifera are unidirectional driven by flagella.They have cellular level organizationDifferent 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

Ctenophora

Phylum: Platyhelminthes (Flatworms)The body of these organisms develop from three germ layers: Ectoderm, mesoderm and endoderm.They have bilaterally symmetrical bodies, with dorsal and ventral surfaces, right and left sides, and anterior and posterior ends. Theres more than 20,000 species that divide in four classes.Parasitic organisms may have evolved from free-living organisms.

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 thats ciliated on the ventral surface.Most are marine, but some are found in fresh water or on land.They eat small animals or dead and decaying material. Food thats not digested exits through the mouth.Excretory: has flame cells whose cilia removes excess water and nitrogenous bases.Nervous: theres eye spots that are sensitive to light and pointed lobes that are sensitive to touch.Reproduction: asexual and sexual.

Classes Trematoda and MonogeneaTrematoda and Monogenea

They both consist of parasitic flukes: leaf-shaped flatworms that parasitize mammals.

Trematoda

Theyre parasitic and leaf-shaped.They have a thick cuticle to prevent digestion from the host.Nervous/Muscular systems are mostly absent.They produce 1,000s of eggs because many die.

TrematodaMonogenea

Class CestodaAbout 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)There are approximately 17,500 species in this phylum.Most live in fresh water, but some live in damp soil and salt water.Theyre transparent, multicellular, and free-living. Males are smaller than females (both may range between 100 to 500m.)They survive long periods without water; however, when wet conditions reappear, they absorb it.Cilia surrounds their mouth and pulls in food.They reproduce in the process of parthenogenesis: unfertilized eggs develop into adults.

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.

Class Polyplacophora

Phylum: Annelida (Segmented Worms) Annelid is a term that comes from Latin meaning little rings.This phylum consists of about 15,000 species of worms.Most have external bristles called setae and some have fleshy protrusions called parapodia.If one segment breaks, the others will still function properly.They have true coeloms and develop from a trochopore.

Nematoda

Arthropoda

Echinodermata

Chordata
