Kingdom Animalia
Characteristics• They are heterotrophic.• All are multicellular.• They all vary in size.• 2 classifications
- Invertebrates: without backbone- Vertebrates: with backbone
• Composed of 9 phyla
Invertebrates
• Porifera• Cnidaria• Platyhelminthes• Nematoda• Annelida• Mollusca• Arthropoda• Echinodermata
Vertebrates
Chordata
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
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
Sea Anemone
Hydra
Phylum Platyhelminthes
• Commonly known as flatworms• Flat bodies• They posses only a hollow sac with a single
opening for food and waste excretion
Liverfluke
Marine Worm
Phylum Nematoda
• Commonly known as roundworms• Round bodies covered with cuticle• Ascaris and hookworms are examples
Phylum Annelida
• Characterized by ring like body parts• Have similar segments throughout their
bodies• Presence of mouth and anus• Have hearts and blood vessels
Phylum Mollusca
• Have soft bodies but they have hard protective shells as outer body covering
• Mussels, clams, and oysters are examples
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
Phylum Echinodermata
• Has a tube feet system of canals • For sucking in seawater to obtain nutrients
and for expelling wastes.
Phylum Chordata
• Three distinguishing structures:-notochord-skull-vertebral column or backbone
Major classes of Vertebrates
• Agnatha (jawless fishes)• Chondrichthyes (cartilaginous fishes)• Osteichthyes (bony fishes)• Amphibia• Reptilia• Aves• Mammalia
Class Agnatha
• Jawless fishes but have sucking mouth parts• No paired fins, jaws or scales• Notochord serves as the skeleton of
agnathans
Class Chondricthyes• Skeletons are made up of cartilage• Have gills, fins and scales• Have toothlike scales
Class Osteichthyes• Called bony fishes• Skeletons are made up of bones• Scales are flattened• Presence of swim bladder
Class Amphibia• They generally live in or near bodies of water• Early stages on water, adult stage on land
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
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
Class Mammalia
• Presence of mammary glands• These secretes milk (in females)• Warm blooded animals• They reproduce through sexual means
QUIZ
• Now that you have learned how diverse living things are (especially plants and animals), please make an essay on how can a Rocesian participate in conserving the biodiversity here in the Philippines.
• Arial, 12, 2” spacing, Narrow margin, short bond paper, maximum of 5 (five pages)
• Submission: Wednesday• Deductions for similar answers will be given.• Please observe honesty with your work.
