Skeletons and Tissue
- Endoskeleton: Internal skeleton found in vertebrates, providing structure and support.
- Cartilage: Flexible connective tissue, softer than bone, aiding in body support.
- Vertebrae: Bony segments forming the backbone, important for structural integrity.
Temperature Regulation
- Ectotherm: Animals whose body temperature depends on external environmental temperatures.
- Endotherm: Animals that internally generate their own heat and regulate body temperature.
Fish Anatomy
- Fins: Essential fanlike structures for movement, turning, stopping, and balance in fish.
- Scales: Protective, thin plates covering fish and reptiles, providing defense against environmental hazards.
Animal Behaviors
- Hibernation: A winter survival strategy involving inactivity and reliance on stored body fat.
- Estivation: A summer state of reduced activity to survive hot, dry conditions.
Reproductive Adaptations
- Amniotic Egg: Shelled, water-retaining egg enabling reproduction of reptiles, birds, and some mammals on land.
Bird Characteristics
- Contour Feathers: Large feathers providing shape and assisting in flight.
- Down Feathers: Soft feathers for insulation, crucial for young birds and adult birds’ warmth.
- Preening: A grooming behavior in birds maintaining feather condition for flight efficiency.
Mammalian Features
- Mammal: Warm-blooded vertebrates characterized by hair covering and mammary glands for nursing.
- Marsupial: Mammals with a pouch (marsupium) for carrying and feeding young.
- Placenta: A nutrient and waste exchange structure in the uterus, essential for fetal development in most mammals.
Animal Groups Overview
- Birds: Warm-blooded vertebrates distinguished by feathers, wings, and egg-laying capabilities, adapted to various habitats.
- Fish: Cold-blooded aquatic vertebrates generally characterized by scales and gills for breathing.
- Amphibians: Cold-blooded vertebrates, with a lifecycle partially aquatic and partially terrestrial.
- Reptiles: Ectothermic vertebrates that lay eggs with scaly skin and possess lungs for breathing.
