The document describes the kingdom Animalia and its characteristics. It is divided into two classifications - invertebrates without backbones, and vertebrates with backbones. It details the 9 phyla of invertebrates and 1 phylum of vertebrates. For each phylum, it provides examples and key distinguishing characteristics such as body structure, organs, and feeding methods. The major classes of vertebrates are also outlined, focusing on distinguishing anatomical features.
4. Phylum Porifera
• Also known as SPONGES
• Have PORES or HOLES in their bodies and a
single large opening called osculum
• Filter feeders
• Has two layers of cells
-epidermal cells
-collar cells
5.
6. Phylum Cnidaria
• Hollow, tube-like bodies
• Presence of nematocyst
• Bodies are composed of two layers of tissue:
epidermis and gastrodermis
• Food is ingested and expelled through the
gastrovascular cavity
9. Phylum Platyhelminthes
• Commonly known as flatworms
• Flat bodies
• They posses only a hollow sac with a single
opening for food and waste excretion
12. Phylum Nematoda
• Commonly known as roundworms
• Round bodies covered with cuticle
• Ascaris and hookworms are examples
13. Phylum Annelida
• Characterized by ring like body parts
• Have similar segments throughout their
bodies
• Presence of mouth and anus
• Have hearts and blood vessels
14.
15. Phylum Mollusca
• Have soft bodies but they have hard
protective shells as outer body covering
• Mussels, clams, and oysters are examples
16. Phylum Arthropoda
• Most diverse of all the phyla
• Exhibits cephalization
• Well developed nervous system (brain and nerve
cord)
• Have segmented bodies
• Body is divided into 3 segments (head, thorax
and abdomen)
• Exoskeleton is made up of chitin
• They molt or shed their exoskeleton as they
grow up
17.
18. Phylum Echinodermata
• Has a tube feet system of canals
• For sucking in seawater to obtain nutrients
and for expelling wastes.
19. Phylum Chordata
• Three distinguishing structures:
-notochord
-skull
-vertebral column or backbone
25. Class Amphibia
• They generally live in or near bodies of water
• Early stages on water, adult stage on land
26. Class Reptilia
• Have hard body coverings (scales or plates)
• Sharp claws on their toes adapted for climbing
and tearing prey
• Cold-blooded organisms
• They breathe through their lungs
• Most are egg laying
27.
28. Class Aves
•
•
•
•
•
Feathers cover the bodies of birds
Presence of beak or bill for food getting
A pair of wings that enables them to fly
Warm-blooded animals
All of them are egg-laying
29.
30. Class Mammalia
•
•
•
•
Presence of mammary glands
These secretes milk (in females)
Warm blooded animals
They reproduce through sexual means
