Study Notes
Vertebrates and Invertebrates
- Animals are broadly categorized into vertebrates and invertebrates.
- Vertebrates possess backbones, while invertebrates lack them.
- Approximately 98% of animals are invertebrates.
- Invertebrates are found in various habitats like forests, deserts, caves, and seas.
- Their nervous systems aid in responding to environmental stimuli.
- Vertebrates represent a smaller portion (about 2%) of the animal kingdom.
- Vertebrates feature internal skeletons composed of bone, providing structure and shape.
- Vertebrate brains are larger and more developed than invertebrate brains.
- They enable quicker responses to environmental cues and facilitate adaptation to different habitats (land, water, air).
- Scientists categorize vertebrates into five groups: fish, amphibians, reptiles, birds, and mammals.
