Many animals are quite similar to each other. Others are quite different. Animals can be classified based on their similarities. invertebrates are apart of the animal kingdom as well as vertebrates. invertebrates are animals without a backbone or spinal column. vertebrates are animals with a backbone or spinal column also. all these are phyla chordata and the subphyla vertebrata.

the environment can be helped, by the help of us. right now if we stopped killing already extinct animals, and animals that we need like for example cows. and the more we cut down forest's the more we don't have trees and the tropical animals that we need also to survive. and polluting the air is something we need to stop doing, the fuels and fume are damaging the air were breathing.

(MOLLUSKS AND CLAMS)

Mollusks were among the first inhabitants of the Earth. Fossils of mollusks have been found in rocks dated back 500 million years ago. Mollusk fossils are usually well preserved because of their hard shell. Most mollusks have soft skin like organ covered with a hard outside shell. Some mollusks live on lands, such as snails and slugs, the Other mollusks live in water, such as the oyster, mussel, clam, squid and octopus.

(ARTHROPODS) an arthropod is an invertebrate animal having an exoskeleton. there members of the phylum arthropoda. that family includes insects, arachnids, crustaceans, and others. Arthropods' primary internal cavity is a hemocoal, which accommodates their internal organs and through which their bloodcirculates; they have open circularity system.

(ECHINODERMS) Echinoderms are a phylum of marine animals. there found at the end of every ocean depth. the phylum family contains about 7,000 species. The echinoderms are important both biologically and geologically. biologically because few other groupings are so abundant in the biotic desert of the deep sea, as well as the shallower oceans, and geologically as their ossified skeletons are major contributors to many limestone formations, and can provide valuable clues as to the geological environment

(EVES) **Birds** (class aves) are feathered, winged, bipdal, endothermic (warm-blooded), egg-laying, vertebrate animals. Around 10,000 living species makes them the most speciose class of tetrapod vertebrates. They inhabit ecosystems across the globe, from the Arctic to the Antarctic. Many species undertake long distance annual migrations, and many more perform shorter irregular movements. Birds are social; they communicate using visual signals and through calls and songs, and participate in social behaviors.
