Biodiversity : Clasification Of Animals

Classification of Animals

 ➤ Invertebrates :     a) more than 90% of animals are invertebrates

                                    b) since invertebrates have no backbone, they are usually small in size

                                        examples :

 

1. Centipede

  2. Sea Anemones Hydras

 3. Brown Rhinoceros Beetle

 4.Earthworm

 5. Burgundy Snail

6. Starfish

Classification of Invertebrates 

1. Sponges :       - simple invertebrates
                           - live in water
                           - they filter food from the water that surrounds them

2. Cnidarians :    - live in water
                           - animals in this group have a central opening surrounded by   
                             tentacles
                           - examples: jellyfish, sea anemones hydras

3. Worms :          - animals with soft, tube-shaped bodies and a distinct head
                           - some worm live inside other animals
                           - examples : earthworm and tapeworm 

4. Mollusks :        - have a muscular foot that allows them to move and hunt for food
                            - some live on land and other live in water
                            - examples : clams, snail and octopuses

5. Echinoderms : - water animals that have a central opening for taking in food
                            - example : starfish

6. Arthropods :    - do have a segmented body
                           - have a bilaterally symmetrical body with a very strong exoskeleton 
                           - can be found in water and in the land
                           - have legs and some have wings

➤Vertebrates :    a) small group compared to invertebrates

                              b) since vertebrates have backbone to support their weight, many 

                                 vertebrates are large in size

                             examples :

 1. Lion Fish

 2. Squirrel

 3. Owl

 4. Tiger

 5. Winter Fox

 6. Chameleon

Classification of Vertebrates

 1. Amphibians :- body covered with moist skin
                          - cold-blooded
                          - carry out external fertilization
                          - breathe with lung on land and through moist skin when in water
 
2. Fish :            - body covered with slimy scales for protection
                         - have fins and tail to swim
                         - breathe through gills
                         - lays eggs ( external fertilization )

3. Reptiles :      - body covered with hard and dry scales for protection
                         - breathe with lungs
                         - cold-blooded
                         - carry out internal fertilization

4. Bird :            - body covered with feathers
                        - have wings and beak
                        - breathe with lungs
                        - warm-blooded

5. Mammals :  - body covered with hair or fur
                       - breathe with lungs
                       - give birth to live young
                       - warm-blooded
