1. Kingdom Animalia
Unit 2 - Biodiversity

2. K. Animalia Characteristics
Multicellular
Heterotrophic
Eukaryotic
Lack cell walls

3. Animal Organization K. Animalia is divided into 9 phyla based on:
Level of organization
(cellular, tissue, organ system etc.)
Body symmetry
(asymmetry, radial, & bilateral)
Cephalization
(concentration of sensory tissue at the head)
Body cavity formation
Coelomate, pseudocoelomate, acoelomate

4. 2 main groups
Invertebrates
Vertebrates
No spinal column
Spinal column

5. Vertebrates
Animals with a spinal cord and an endoskeleton.

6. Fish Aquatic, have fins, scales and gills.
Herbivores, carnivores, parasites and filter feeders.
Sexual Reproduction– eggs fertilized internally or externally
Bilateral body symmetry
Ectothermic or cold blooded
Found in water

7. Amphibians
Their skin is usually smooth and lacks scales, hair, and feathers. Their skin must remain moist to aid in breathing. They lack claws on their toes.
Herbivores as youth and carnivorous as adults.
Sexual reproduction – eggs fertilized internally or externally
Bilateral body symmetry
Ectothermic or cold blooded
In water as larva and on land as adults.

8. Reptiles
Their skin has scales and is dry. They have claws on their toes, teeth and lay eggs on land.
Herbivores and carnivores
Sexual Reproduction – eggs fertilized internally.
Bilateral
Ectothermic or cold blooded
Found in Temperate Climates

9. Birds
Their skin is covered with feathers. They have four- chambered hearts. Their bones are lightweight and usually hollow. Their forelimbs are modified as wings. They lay eggs.
Herbivores and carnivores
Sexual reproduction – eggs fertilized internally.
Bilateral Symmetry
Endothermic or warm blooded
Found everywhere.

10. Mammals
They have hair, which varies greatly among species. Most have sweat glands. They have mammary (milk-secreting) glands to feed their young.
Herbivores and carnivores
Sexual Reproduction – fertilized internally.
Bilateral body symmetry
Endothermic or warm blooded
Found almost everywhere

11. Invertebrates
No spinal column
Some with exoskeletons

12. Porifera (poh-RIF-ur-uh)
Sedentary. Body is made of cells and tissues surround by a water filled space but there is no true body cavity.
filter feeders
Sexual & asexual (budding)
Asymmetrical body symmetry
Ectothermic or cold blooded
Live in aquatic environments, mostly marine.

13. Cnidaria (ny-Dayr-ee-uh)
Are all radial in symmetry, have stinging tentacles to catch prey.
carnivorous and filter feeders
Sexual & asexual (budding) reproduction
Radial Symmetry
Ectothermic or cold blooded
Marine and fresh water

14. Platyhelminthes (plat-ih-hel-min-theez)
Most are free living and parasitic.
carnivores and parasitic
Sexual (hermaphrodites) & asexual (fission) reproduction
Bilateral body symmetry
Ectothermic or cold blooded
Marine and fresh water

15. Nematoda (nee-muh-ToHD-uh)
Most are free living and parasitic.
herbivores, carnivores and parasitic
Sexual and hermaphroditic reproduction
Bilateral body symmetry
Ectothermic or cold blooded
Live just about everywhere.

16. Mollusca (mol-us-ka)
Soft body and sometimes a hard shell Bodies are divided into 3 parts: Head, Foot, and Visceral Hump.
filter feeders, herbivores and carnivores
Bilateral symmetry
Ectothermic or cold blooded
Marine, fresh water and land

17. Arthropoda (arth-rop-a-da)
A hard outer body covering called an exoskeleton.
Specialized mouth parts. Jointed legs. Compound Eyes. Segmented body
herbivores, carnivores, ominovores
Sexual (internally and externally) reproduction
Bilateral body symmetry
Ectothermic or Cold blooded
Found in aquatic and terrestrial environments

18. Annelida (uh-Nel-ih-duh)
Soft body worms with sections, possesses a through gut, mouth and anus.
Some parasitic
Sexual and hermaphroditic reproduction
Bilateral body symmetry
Ectothermic or coldblooded
Found in soil and fresh water

19. Echinodermata (ee-Ky-noh-durmata)
Have bodies with rough skin and sharp spines, possess 5- rayed symmetry. Calcareous skeleton
Sexual (separate sexes) and asexual (regeneration) reproduction
Radial body symmetry
Ectothermic or Cold blooded
Found in marine environments
