Study Notes
Animal Kingdom Classification
- Divided into two main phyla: Vertebrates (with backbone) and Invertebrates (without backbone).
- Vertebrates consist of five classes, which include fish, amphibians, reptiles, birds, and mammals.
Invertebrates
- Includes various animals, which are classified based on structures like exoskeletons or body parts.
Vertebrate Classes
- Fish: Breathe through gills and have scales and fins.
- Amphibians: Live in water as juveniles and on land as adults; lack scales but may have fins.
- Reptiles: Land animals covered in scales; breathe using lungs.
- Birds: Noted for feathers; most can fly.
- Mammals: Covered in hair, maintain a constant body temperature, and produce milk for their young.
Characteristics of Animals
- Complex cells make up all animals.
- Heterotrophs: Animals cannot produce their own food and rely on consuming plants and other animals.
- Endoskeleton in vertebrates provides organ protection and body support.
- Warm-blooded vertebrates maintain a constant body temperature, including mammals and birds.
- Cold-blooded vertebrates' body temperature varies with the environment, including fish, amphibians, and reptiles.
Reproductive Characteristics
- Mammals typically gestate their young inside the mother's body; some may develop in pouches or hatch from eggs.
Additional Animal Classes
- Insects: Possess an exoskeleton, segmented bodies with three parts: head, thorax, and abdomen.
- Arachnids: Have a hard exoskeleton and jointed appendages; typically have eight legs.
- Crustaceans: Live in aquatic environments, usually having a hard outer shell.
- Mollusks: Generally soft-bodied with some covered by a hard outer shell.
- Echinoderms: Marine animals known for having arms or spines radiating from a central body.
Sensory and Physical Features
- Antennae serve as sense organs on the heads of arthropods.
- Molting is the process of shedding an exoskeleton in arthropods.
Body Structures
- Coelom: A fluid-filled body cavity containing internal organs.
- Insects have six legs, spiders have eight, and crabs typically have ten legs.
Fossil Record
- Fossils provide evidence of historical fauna, leaving prints or marks as remnants of their existence.
