Animal Way of life BY: Lavelle Caldwell



 Phylum Mollusk: Largest and most diverse form of an animal right along with anthropods. they are found in almost every ecosystem on da earth. its almost 100,000 species of mollusks known today. the body of mollusks is composed of a shell and it is a fleshy living part.the flashy part of the mollusk can be divided into the foot and visceral mass. A distinctive Molluscan feature is the foot. Locomotion makes it differ in a variety ways. 2 external flaps are on the mantle. the mantle is made up of tissue.  The Classification- most of these mollusks can be told different by looking at the feet. A type of mollusk is the Gastropoda. Gastropoda is the biggest class of mollusks. 35,000 living species including snails, periwinkles,  conches, whelks, limpets and sea slugs. Another form of Mollusks is the Bivalvia. and the bivalvias members of this class is clams, cockles, mussels, oysters and scallops. Humans eat all of thoughs.



The arthropods constitute over 90% of the animal kingdom and are classified in the phylum Arthropoda. If you wanted to know how to distinguish them from other animals you can look at the exoskeleton. Its body is split into different parts. Legs are jointed. They have bilateral symmetry.



The Echinodermata has about 6000 species. its a greek name it means spiny skin. these animals are really simple animals. These animals don't have a brain. Characteristic of all echinoderms is the presence of an internal skeleton covered with spines and skin.



 The skeleton is bony on the birds (aves). Its also aerodynamically suitable for flying. Birds breathe with lungs but they don't extend. Lung capacity is extended by 5 pairs. A characteristic that all birds have is laying eggs. They have 3 main layers in the egg. Female birds only have one ovary. There are often differences in sexes. sexual dimorphism thats what its called.
