    Study Notes

    Animal Kingdom Classification

    • The animal kingdom is divided into two main groups: invertebrates (no backbone) and vertebrates (with backbone).
    • Invertebrates contain the largest number of species within the animal kingdom.

    Definitions

    • Vertebrate: An animal with a backbone.
    • Invertebrate: An animal without a backbone.
    • Classification: The process of organizing organisms by a specific set of rules.

    Groups of Vertebrates

    • Vertebrates are categorized into five classes:
      • Amphibians: Moist skin, no scales, begin life in water, most adults live on land, undergo metamorphosis.
      • Fish: Covered in scales, use gills for breathing, live entirely in water.
      • Reptiles: Scaly skin, mostly lay eggs, cold-blooded.
      • Mammals: Have hair, produce milk for young through mammary glands, typically give live births.
      • Birds: Covered in feathers, adaptations for flight, usually lay eggs.

    Characteristics of Classes

    • Amphibians: Require water for development, begin life aquatic, adults often terrestrial.
    • Birds: Feathers provide insulation and enable flight.
    • Fish: Gills for underwater respiration, scales for protection.
    • Mammals: Hair for warmth, mammary glands for feeding young.
    • Cold-blooded Animals: Maintain body temperature based on environmental conditions.
    • Warm-blooded Animals: Maintain a constant body temperature regardless of the environment.

    Additional Classification Insights

    • Animals can also be classified as cold-blooded (amphibians, reptiles, fish) or warm-blooded (birds, mammals).
    • Fish and reptiles are identified by having scales.

    Habitats and Adaptations

    • All animal classes depend on water for survival in various ways—amphibians start life in water, fish live in water, and some mammals and birds hunt or swim in aquatic environments.
    • Amphibians exemplify a class that begins life in water but transitions to land as adults.

    Breathing Mechanisms

    • Fish breathe using gills, which allow them to extract oxygen from water.
    • Backbone consists of a series of bones linked by cartilage, providing structural support.

    Verification of Vertebrate vs Invertebrate

    • Examples of invertebrates: starfish, octopus, jellyfish, crab.
    • Examples of vertebrates: shark, whale, newt, snake, eagle, turtle.
    • Invertebrates lack a backbone, while vertebrates possess one.

    Reproductive Strategies

    • Classes laying largely eggs: birds, amphibians, fish, and reptiles.
    • Mammals uniquely provide nourishment through breast milk, a defining characteristic.
