Kingdom Animalia consists of multicellular eukaryotes that are heterotrophic. It is divided into vertebrates and invertebrates. Vertebrates include mammals, birds, reptiles, amphibians, and fishes. Mammals are warm-blooded and feed their young with milk, while birds have feathers and wings. Reptiles have scales and are cold-blooded. Amphibians live in water as larvae but live on land as adults. Invertebrates lack backbones and include groups such as arthropods, mollusks, and worms.
2. 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
3. Kingdom Animalia are divided into 2 groups
1. Vertebrates
- animals with backbones
2. Invertebrates
- animal without backbone
4. 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
6. 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
8. 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
10. 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
12. VERTEBRATES
5. FISHES
- they have scales as body covering
and they breathe through the gills
- they also have lungs for breathing
- bangus, lapu-lapu and dalagang bukid are
all bony fishes
- sharks and rays are cartilagenous fishes
14. 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
17. INVERTEBRATES
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
21. 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
23. 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
24. 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
26. 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
28. 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
