2. • 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.

4. • 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.

8. • 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.

11. • 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.

13. • 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.

16. • 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.

18. • 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 mmlong
• Mostly found in freshwaters

20. • 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.

23. • 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.

25. • 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.

27. • 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.

30. • 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.

33. • include the insects, arachnids, and crustaceans. The
wordarthropod comes from the Greek ἄρθρονárthron ,
"joint", and πούςpous (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.

40. • Are animals with notochord
and pharyngeal gills slits at
some stage in their life history.

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

43. • Jawless vertebrates

44. • cartilaginous

45. • Bony Fishes

46. • Amphibians

47. • Reptiles

48. • Feathered Animals

49. • Mammals
