Transcript Kingdom Animalia

KINGDOM
ANIMALIA
CHARACTERISTICS
 Far more diverse than Kingdom Plantae
 Consist of the most complex organisms
consisting of about 2 million species
 Heterotrophic, multicellular eukaryotes
belongs to this kingdom
 Vary in size – ranging from microscopic to
the most gigantic creatures
Kingdom Animalia are divided into 2 groups
1. Vertebrates
- animals with backbones
2. Invertebrates
- animal without backbone
VERTEBRATES
1. MAMMALS
- covered with hair and they have mammary
glands
- these gland secrete milk of females who
have just delivered their young
- warm-blooded animals
Ex. Cats, dogs, goat, whales and dolphins

VERTEBRATES
2. BIRDS
-feathers cover their body
- they have beaks or bill which they used
to get food
- they have a pair of wings that enable
them to fly
- they are also warm blooded animals that
lay eggs from which their young is hatched

VERTEBRATES
3. REPTILES
-they have thick, dry scales that
cover the bodies of reptiles to
prevent the excessive loss of water
- they are cold blooded animals
- some have four legs, while others
have no legs at all

VERTEBRATES
4. AMPHIBIANS
- live in water during the early stage of
their life and begin to stay on land where
they can get enough food
- body is covered by a thin, flexible and
usually moist skin
- their eggs are fertilized externally

VERTEBRATES
5. FISH
- they have scales as body covering
and they breathe through the gills
- they also have lungs for breathing
- red snappers are all bony fishes
- sharks and rays are cartilagenous fishes
FISHES
INVERTEBRATES
1.
PHYLUM ECHINODERMATA
- marine organisms with spiny skins
- from the Greek terms echinos (meaning
hedgehog) and derma (meaning skin)
- the tube feet and system of canals in the
body that serves as a channel for sucking in the
sea water to obtain nutrients and for vomiting
sea water

2.
PHYLUM ARTHOPODA
- they have a pair of 3 or more jointed legs
- from the Greek term arthron ( meaning
joint) and podus (meaning foot)
- they have an exoskeleton or hard outer body
covering made up of chitin
- the largest phylum in kingdom Animalia

INVERTEBRATES
3. PHYLUM MOLLUSKA
-they have soft body
- from Latin term mollis, which means
soft
- most have protective shells as the
outer covering

INVERTEBRATES
4. PHYLUM
ANNELIDA
-characterized by ringlike body parts
- they are worms with segmented body
- they have a mouth at the front and anus at
the tail end of their bodies
- they have hearts and blood vessels that
constitute a circulatory system
ANNELIDS
INVERTEBRATES
5. PHYLUM NEMATODA
- roundworms are cylindrical worms
with a finely tapered tail
- the body is covered with a tough,
non living skin that resist drying and
crushing
INVERTEBRATES
6. PHYLUM PLATYHELMINTHES
- the simplest worm
- some of them are free living while
others are parasitic, living in the bodies
of animals including humans
FLATWORMS
INVERTEBRATES
7. PHYLUM CNIDARIA
- posses stinging structures called
nematocysts in their tentacles
- characterized by a hallow, tube like
bodies, with a mouth at the end
CNIDARIANS
INVERTEBRATES
8. PHYLUM PORIFERA
- pore-bearing organisms
- they may live singly or in colonies
- they eat by allowing water to flow
through their bodies and trapping small
organisms in the water using their
specialized cells
PORIFERANS
