characteristics
Characteristics
  • Some eat plants, some eat animals, and some eat both.
  • Herbivores, Carnivores, Omnivores
  • Digest their own food
  • Move from place to place to find food, mates, places to live, and to escape enemies.
  • Multi-cellular
  • Eukaryotic
  • 9 major groups (Phylums)
    • Most of these groups are invertebrates
2 major sub groups
2 Major Sub-Groups
  • Invertebrates
  • Vertebrates
invertebrates
Invertebrates
  • No backbones
  • Have an outside covering or are supported by the water they live in
  • Contain:
    • Coelentrates (hydra)
    • Sponges
    • Flatworms (tapeworm)
    • Roundworms (hookworms)
    • Segmented worms (earthworm, leeches)
    • Mollusks (clams, oysters)
    • Arthropods (lobsters, insects)
    • Echinoderms (sea stars)
vertebrates
Vertebrates
  • Have a backbone
  • Endoskeleton provides support for the body and aids in movement
  • Contains:
    • Jawless fish (lamprey)
    • Cartilaginous fish (sharks)
    • Bony fish (catfish)
    • Amphibians (frog)
    • Reptiles (turtle)
    • Birds
    • Mammals
major groups phylums
Major groups (Phylums)
  • Porifera
  • Cnidaria
  • Platyhelminthes
  • Nematoda
  • Annelida
  • Mollusca
  • Arthropoda
  • Echinodermata
  • Chordata
porifera
Porifera
  • The simplest of the animal groups.
  • Most adult sponges live in slat water, attached to the sea bottom or some other object.
  • A sponge’s body is composed of 2 layers of body cells.
  • These body cells cling to a network of tiny spikes or fibers that surrounds the hollow central cavity of the sponge.
  • Water and wastes leave through a large opening on the top.
cnidarians
Cnidarians
  • Simple animals whose bodies are composed of two specialized layers of cells (tissues) separated by a jelly-like substance
  • All live in water and have a hollow sac-like body that has a single opening through which food enters and wastes are expelled.
  • Sometimes these openings are surrounded by tentacles lined with stinging cells.
  • Examples: Hydras, jellyfish, sea anemones, and corals.
platyhelminthes
Platyhelminthes
  • Flatworms
  • Have a flattened body with one body opening, a digestive system, and a simple nervous system.
  • Examples:
    • Turbellarians are free living flatworms
    • Blood flukes, liver flukes, and tapeworms are parasitic flatworms.
nematoda
Nematoda
  • Roundworms
  • Named for their rounded body shape.
  • Have a straight digestive tube and two body openings—one for taking in food and another for getting rid of wastes.
  • Most are free-living found in pond water or in moist soils.
  • Some are parasitic on animals or plants.
    • For example, ascaris worms and hookworms live in the intestines of humans and other mammals.
annelida
Annelida
  • Segmented worms
  • Have rounded bodies with 2 body openings divided into a series of segments.
  • Examples: earthworms, leeches, and marine tube worms.
mollusca
Mollusca
  • Soft-bodied animals with well-developed organ systems.
  • Many mollusks have hard shells made up of calcium to protect their bodies.
    • Examples: clams and oysters
  • Octopuses and squids are also mollusks but they have tentacles, but no external shell.
arthropoda
Arthropoda
  • By far the largest group of animals.
  • Characterized by multiple body segments and jointed appendages.
  • Live successfully in water or on land.
  • May have complex lifecycles (multiple phases.)
  • Arthropods have a hardened exoskeleton that protects their well-developed organ systems.
  • An exoskeleton is a hard outer covering for protection.
    • Example arthropods: insects, spiders, crabs, shrimp, lobsters, centipedes, and millipedes.
echinodermata
Echinodermata
  • Move by using special structures called tube feet, which resemble suction cups.
  • Known for their ability to regenerate missing parts.
  • This is the ability to grow new body parts in place of missing ones.
    • Example organisms: Sea stars, sea urchins, sand dollars, and sea cucumbers.
chordata
Chordata
  • Phylum contains the following groups:
    • Jawless fishes
    • Cartilaginous fishes
    • Bony fishes
    • Amphibians
    • Reptiles
    • Birds
    • Mammals
jawless fishes
Jawless fishes
  • Have jawless mouths adapted for sucking body fluids from other fishes
  • Have elongated snake-like bodies with no appendages.
  • Gills for obtaining oxygen
  • Flexible skeletons of cartilage
  • Like all other fishes they are ectotherms.
    • This means that they have a body temperature that changes according to the temperature of the environment.
  • Example: The Sea Lamprey
cartilaginous fish
Cartilaginous fish
  • Animals such as sharks
  • Generally live in the ocean
  • Have skeletons made of cartilage, 2 fleshy fins, gills, and strong jaws with many rows of teeth for tearing and eating flesh.
  • Stingrays and skates are other members of this group.
bony fishes
Bony fishes
  • The most numerous and varied kind of fishes
  • Have gills and skeletons made of bone
  • Most have a stream-lined body that is tapered at both ends and 2 pairs of fan-like fins
  • Their fins and body shape allow them to move easily through the water
  • Examples: catfish, goldfish, flounder, eels, trout, etc.
amphibians
Amphibians
  • Name amphibian means “double life”
  • Most amphibians live part of their lives in water and part on land.
  • Most amphibians have 2 pairs of legs as adults.
  • Amphibians lay their eggs in water and are ectotherms
  • Usually have smooth skin that must be kept moist.
  • Most have gills when they are young and lungs as adults.
    • Examples: frogs, toads, and salamanders
reptiles
Reptiles
  • Many have 2 pairs of strong legs with clawed toes for digging, climbing, and moving on land.
  • Covered by hard plates or scales that prevent water loss by evaporation.
  • Lay eggs that are surrounded by a tough, leathery shell that prevents them from drying out.
  • Breath with lungs and are ectotherms.
    • Examples: turtles, snakes, lizards, crocodiles, and alligators.
birds
Birds
  • Have light, hollow bones and enlarged lungs as adaptations for flying.
  • Body covering of feathers and a pair of wings
  • Scaly legs and feet with clawed toes
  • Lay eggs covered by a hard shell.
  • Are endotherms
    • This means that they have a body temperature that remains constant despite temperature changes in the environment.
mammals
Mammals
  • Have a very advanced nervous system, which includes a highly developed brain and keen senses.
  • Feed their young with milk from mammary glands
  • Have hair on their bodies and breathe with lungs
  • Endotherms
  • Found on land, in the air, and in water.
  • One small group of mammals lay eggs but all other give birth to live young.
  • Examples: Lion, human, dolphin, bat
