Animal ClassificationE.Q. How do scientists classify living organisms? S5L1
Five Kingdoms of Classification • Scientists classify living organisms so that they can easily share information and discuss organisms in a way that everyone can understand. • Five Kingdoms • Animals (snail, jellyfish, worm, mosquito) • Plants (algae, moss, dandelion, rose, oak tree) • Bacteria(Monera) (salmonella,halobacterium, blue-green algae) • Fungi (mushroom, mold, puffball, yeast, fungus) • Protist (amoeba, euglena, paramecium)
Seven Levels of Classification • All living organisms can be broken down into the seven levels of classification from the largest (kingdom) to the smallest (species) • KINGDOM- Kings • PHYLUM- Play • CLASS- Chess • ORDER- On • FAMILY- Funny • GENUS- Green • SPECIES- Squares
Let’s look at the seven levels of classification for a human: • Kingdom: Animal • Phylum: Chordata (animals with backbones) • Class: Mammalia • Order: Primates • Family: Hominidae • Genus: Homo • Species: Sapien Scientific Name: Genus+ Species= Homo sapien (Latin Name)
Animals are divided into two Main categories Vertebrates- animals that have a backbone 1.Fish 2. Amphibians 3.Reptiles 4.Mammals 5. Birds Invertebrates- animals without a backbone 1. Annelids 2. Echinoderms 3. Mollusks 4. Arthropods
Vertebrates-Animals with backbones 1. Fish- cold blooded animals that have scales, gills, fins, and lay eggs Examples: trout, bass, eel 2. Amphibians-cold-blooded animals that have smooth skin and can live on land or in water Examples: frogs, toads, salamanders 3. Reptiles-cold-blooded animals that have scales and lungs and lay eggs Examples: turtles, snakes, lizards, alligators 4. Mammals-warm blooded animals that have hair or fur and are born alive (feed milk to their young) Examples: humans, dogs, rabbits, lions, whales 5. Birds-warm blooded animals that have feathers and lay eggs Examples: eagles, turkeys, doves Warm- blooded- animals that have body temperatures that stay the same Cold-blooded- animals that have body temperatures that change with the temperature of their environment
Invertebrates- Animals without backbones 1. Annelids-cold-blooded animals that have soft bodies with sections Examples: earthworms, clamworms, leeches 2.Echinoderm- cold-blooded animals that have bodies with rough skin and sharp spines Examples: sea star, sea urchin, sand dollars 3. Mollusk- cold-blooded animals with a soft body and sometimes a hard shell Examples: clams, oysters, snails, octopuses, squid 4. Arthropods- cold-blooded animals with jointed legs Examples: spiders, insects, crabs, lobsters
