The following will be explained about some of the phyla of
the kingdom Animalia both invertebrate and vertebrate groups. Phyla are
Porifera, Cnidaria, Plathyhelminthes, nematodes, annelids, molluscs,
Echinodermata, arthropods and chordates. You interested? Consider the following
explanation.
1. Phylum Porifera
Sponge hardly recognizable as animals. Phylum Porifera also called sponge animals. Sponge is a simplest multicellular animals, they do not have a head or other body members like animals. Therefore, many are mistakenly identified as a plant sea sponges. More ...
2. Phylum Cnidaria
Phylum Cnidaria is a collection of interesting animals that exist in the waters. Jellyfish, sea anemones, and corals are gracefully is an example of living creatures that belong to the group of this phylum. More ...
3. Phylum Platyhelminthes
Members of the phylum Platyhelminthes not have the body cavity and consists of three layers of the body (triploblastik). Oxygen diffuses through the skin directly. Likewise, carbon dioxide diffuses from the body directly into the environment. More ...
4. Phylum Nematode
Nematodes are not segmented worms cylindrical, having a body cavity triploblastik (pseudocoelom), and free-living and parasitic. Nematode worms also called roundworm. Can be found in the waters, wet soil, plant tissues, and tissues of animals or humans. Having a perfect digestive system and body fluids in the coelom which serves as the circulatory system. More ...
5. Phylum Annelida
The two main characteristics in annelid phylum is to have a true body cavity and segmented body. Each of these segments called somites. The structure of the somites-somites in worms called metameri. Annelids have a closed circulatory equipped blood vessels. The nervous system consists of the brain and nerve cord called neural system rope ladder. Annelids are divided into three classes, namely Polychaeta, Oligochaeta and Hirudinea. More ...
6. Phylum Mollusca
Molluscs is a group of soft-bodied animals. Molluscs comes from the Latin meaning molluscus software. More ...
7. Phylum Echinodermata
All Echinoderms live in the sea. There are more than 5,000 species in this phylum, such as starfish, sea urchin and sea cucumber. Echinoderms like molluscs, have coelom and the digestive system is complete. More ...
8. Phylum Arthropods
Phylum arthropods are the most rich in the species. The number of species estimated at 75% of the animals in the world. Spread his place of land, freshwater and seawater. Arthropod phylum members jointed body and have exoskeletons. His body was coated by epikutikula consisting of chitin results hypodermic secretion. Body and legs are divided into segments. Skin changes occur within a specific time interval. Located in the ventral nervous system. Open blood circulation and the heart is located in the dorsal. More ...
9. Phylum Chordata
Chordates covering about 45,000 species of animals that live in almost any kind of environment. There are three things that distinguish phylum Chordata the other phyla, namely in terms of perkembanganny

Chordates covering about 45,000 species of animals that live
in almost any kind of environment. There are three things that distinguish
phylum Chordata the other phyla, namely in terms of development.
Notochord, which is a supporter in the dorsal stalk precisely under the nervous system. Notochord serves as a support. On vertebrate animals all embryos have a notochord.
Nerve cord (nerve cord), which is a hollow nerve at the top of the notochord.
Pharyngeal gill pouches (pharyngeal gill pouches).
Chordates can be divided into two groups, namely Chordata invertebrates (Chordata Vertebrates) and Chordata invertebrates (invertebrate chordates). Chordates are vertebrates, ie vertebrates. As Chordata invertebrates, among others, Urochordata and Cephalochordata. Examples Urochordata species is Halocynthya, while Cephalochordata example is Branchiostoma.
In this section, only will be discussed on Chordata Vertebrates. Vertebrate animals (vertebrates) is the largest group in the Chordata, which is divided into five classes, Pisces, Amphibia, Reptilia, Aves, and Mammalia.
a. Class Pisces
Based on the type of bone that build the framework of his body, Pisces (fishes) are grouped into two groups, namely cartilaginous fish (Chondrichthyes) and bony fishes true (Osteichthyes).
Notochord, which is a supporter in the dorsal stalk precisely under the nervous system. Notochord serves as a support. On vertebrate animals all embryos have a notochord.

a. Class Pisces
Based on the type of bone that build the framework of his body, Pisces (fishes) are grouped into two groups, namely cartilaginous fish (Chondrichthyes) and bony fishes true (Osteichthyes).
1). Cartilaginous fish (Chondrichthyes)
Chondrichtyes class has approximately 850 species of fish. They have jaws, many teeth, fins are paired, and the order in which are made of cartilage. Grade fish is considered a living fossil because it is a descendant of ancient animals that have inhabited the sea since hundreds of millions of years ago.
Fish Chondrichthyes have five to seven gill slits on either side of the pharynx and do not have gill cover as is commonly found in the genuine bony fish. Some types of cartilaginous fish that are still to be found are sharks, stingrays, fish and lamprey.
2). True bony fish (Osteichthyes)
True bony fish have a framework that consists of hard bone. There are about 20,000 kinds of true bony fish that can be found both at sea and in fresh water. Osteichthyes can be divided into two groups, namely sarcopterygii and Actinopterygii. The most abundant species of fish are fish Osteichythyes class Actinopterygii. Some fish Actinopterygii suspected nothing to do with ancestors Amphibia. Examples of invertebrate species of true among others, catfish (Ameiurus melas), eel (Anguilla sp), and carp (Cyprinus Caprio). Consider the following picture.
2. Class Amphibia
This class includes 4,000 species of animals that undergo stages of larvae in the water and after adult living on the mainland. Therefore, called Amphibian. Amphibians usually have to go back into the water when it will mate and lay eggs. Amphibians Most adults have moist skin that helps his lungs are small and inefficient in gas exchange.
Amphibious term means having two realms, namely on water and land. Amphibians issued their eggs into the water when performing external fertilization or conception, as happened to the fish. Typically, amphibian eggs are not protected by a shell, but it is protected by a mucus. Larvae generally experience changes shape when it develops into the adult form that lives on land.
Amphibians, like the fish, is poikilotherm animals. That is, the temperature of the body can adapt to its environment. If the ambient temperature is too low, animals poikilotherm become less active. Examples Amphibian species include toads (Bufo marmus), green frog (Rana pipiens), and salamanders (Axolot). Consider the following picture.
C.class Reptilia
Reptiles comes from the Latin, which means snake reptile. Reptiles generally poikilotherm. Reptiles also known as reptiles. Slithers a walk way by attaching the stomach to the ground. Reptilia consists of approximately 6,000 species of animals, including snakes, lizards, turtles, and crocodiles. Reptiles lay eggs which are protected by a thick skin and internal membranes. Reptiles internal fertilization.
Like Amphibia, Reptilia also an animal which absorbs heat from the outside environment. Therefore, you may often see lizards sunning. Examples of reptiles, among others python (Python reticulatus), dragons (Varanus) and lizards (Lacerta agilis).

d. class Aves
Class Aves (birds) consists of about 9,000 species. The whole body of the bird is covered by feathers, except for the feet and beak. Feathers and bird's beak made of keratin. Birds do not have teeth to chew their food, but it has cached.

Birds have wings that can help him fly. However, there are
some birds that can not fly, for example, cassowary and ostriches. Can you
mention other examples? Birds are the animals that their body temperature stays
(homoioterm). Birds breathe with lungs. In addition, the birds breathing is
assisted by the coffers of the air when flying.
Bird fertilization in the female body. Once fertilization occurs, the birds will lay eggs and will incubate until hatched. Examples of species of class Aves, among others, chicken (Gallus domestica), pigeons (Columba fasciata), a sparrow (Passer Montanus), and swan (Cygnus sp.).
e. Class Mammalia
Mammalian derived from the Latin, meaning that breast milk glands. Mammalia class consists of about 5,000 species are grouped into 26 orders. The general characteristics of the Mammalia are:
hair;
has three bones in the middle ear;
have mammary glands.
Mammals have a larger brain volume compared with other Vertebrate animals. Mammalia body temperature remains or not influenced by the outside environment temperature (homoioterm). Respirator mammal is lung. Mammals also have high adaptability.
Mammals adaptation of which is as follows.
Mammals developed several ways of adaptation behavior that helped successfully survive.
Mammalia dental work cutting, tearing and chewing. In addition, the teeth have email thick that protects the teeth.
Mammals have the ability to move quickly.
Larger brain size compared with almost all other animals.
Mammals have control of efficient control of body temperature compared with the group of birds.
Have a functioning hair as insulation or heat insulation.
Milk glands provide milk for young animals.
Mammalia grouped by various criteria. Examples grouping based on food (eg carnivores) and based on the shape of the teeth (for example, rodentia).
Mammals have a lot of orders. Here are a few orders on the mammal as follows.
Monotremes (Mammalia beaked), for example Platypus (Ornitherynchus anatinus).
Carnivores (meat-eating mammal), for example, cats (Felis domestica).
Rodentia (Mammalia rodents), for example, mice mice (Mus musculus).
Cetacea (Mammalia water), for example the pope (Balanoptera borealis).
Chiroptera (Mammalia besayap), for example, bats (Myotes sp.).
Marsupials (pouched mammal), for example kangaroo (Macropus sp.).
Probosoidea (Mammalia berprobosis), for example, elephant (Elephas maximus).
Primates, for example bekantan (Nasalis larvatus).
Bird fertilization in the female body. Once fertilization occurs, the birds will lay eggs and will incubate until hatched. Examples of species of class Aves, among others, chicken (Gallus domestica), pigeons (Columba fasciata), a sparrow (Passer Montanus), and swan (Cygnus sp.).
