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.
