Kingdom Animalia• The major group of animals are classified under the Kingdom Animalia, also known as Metazoa. This kingdom does not contain prokaryotes. All the members of this kingdom are multicellular, eukaryotes. 'animal' is derived from the Latin word animalis which means 'having breath'• They are heterotrophs, they depend on other organisms directly or indirectly for food. Most of the animals ingest food and digest in the internal cavity. Most of the organisms are motile which means they can move independently and spontaneously.

Kingdom Animalia

Classification

• These are simple sessile animals with no organized tissues or organs. They are marine filter feeders. They are primitive organisms; most of them are salt-water sponges. They do not have organs or nerve cells or muscle cells. Approximately, 8,000 species exist today.

Phylum Porifera

Sycon

Euspongia

Spongilia

• Hollowed bodied animals. Their bodies are made of inner outer developed tissues with gastro-vascular cavity with no anus. This group is composed of jelly-fish and other lower aquatic animals. Approximately, 15,000 species exist today.

Phylum Coelentrata (Cnidaria)

Aurelia

Adamsia

• Ctenophores. They were once classified with cnidaria but most of them have no nematocyst.

•  a small phylum containing about 90 species of generally small and delicate animals known as

Comb Jellies. Many species are quite and many are also almost transparent, a few species can be very beautiful as they have the ability to produce green and blue coloured light. There are between 100 and 150 species of Ctenophora known to science.

Phylum Ctenophora

• This group consists of flat worms. They inhabit both marine and fresh water habitats and they are mostly endoparasites found in animals. 

• They exhibit three well-developed tissues and organs.

Phylum Platyhelminthes

Taenia

Planaria

• Ribbon worms. These are long flattened worms with anus and circulatory system.

• Although most are less than 20 centimetres (7.9 in) long, one specimen has been estimated at 54 metres (177 ft), which would make it the longest animal ever found. Most are very slim, usually only a few millimeters wide, although a few have relatively short but wide bodies. Many have patterns of yellow, orange, red and green coloration.

Phylum Nemertina

• Rotifers. They are called wheeled animalcule for their sequentially beating ring of cilia around their mouth.

• most are 0.1-0.5 mm; but some up to 3 mm long

• Mostly found in freshwaters

Phylum Rotifera

Philodina

• Roundworms. They have fluid filled body cavity called pseudocoelum with a mouth and anus.

• They are a diverse animal phylum inhabiting a very broad range of environments. Nematode species can be difficult to distinguish, and although over 25,000 have been described, of which more than half are parasitic, the total number of nematode species has been estimated to be about 1 million.

• Unlike cnidarians and flatworms, nematodes have tubular digestive systems with openings at both ends.

Phylum Nematoda

Ascaris

Pinworm

• Mollusks. Their soft body is covered by a mantle, which secretes shell.

• Mollusks are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and in anatomical structure, but also in behaviour and in habitat.

Phylum Mollusca

Snail Octopus

• also known as Polyzoa, Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals.

• They are mostly microscopic animals forming fixed colonies in shallow fresh water or marine habitat.

• Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia.

Phylum Bryozoa

•  also called "ringed worms", formally called Annelida (from Latin anellus "little ring"), are a large phylum of segmented worms, with over 17,000 modern species including ragworms, earthworms and leeches.

• They show primitive metamerism or segmentation.

• Various forms specialise in their respective ecologies; some in marine environments as distinct as tidal  and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments.

Phylum Annelida

Earthworm

Leech

• Spiny skinned. The adult form has spiny exoskeleton of plates and calcerous epidermis.

• This consists of sea stars and sea urchins. There are about 6,000 species. 

Phylum Echinodermata

Asteria

Ophiura

Phylum Arthropoda• include the insects, arachnids,

and crustaceans. The word arthropod comes from the Greek ἄρθρον árthron, "joint", and πούς pous (gen. podos), i.e. "foot" or "leg", which together mean "jointed leg".

• This is the largest phylum which consists of insects. There are over 1 million species of insects existing today. 

• Joint legged. Their bodies and appendages are segmented and with exoskeleton containing chitin.

INSECTS

CRUSTACEANS

DIPLOPODS

ARCHNIDS

CHILOPODS

Phylum Chordata• Are animals with notochord

and pharyngeal gills slits at some stage in their life history.

Subphylum Vertebrata

• Vertebrates. The notochord is replaced from cartilage to segmented vertebral column and bony skull.
