Study Notes

Introduction to Zoology

Zoology is the science of animal knowledge, encompassing structure, habits, and classification.
A person skilled in zoology is referred to as a zoologist.

Definition and Scope of Animals

The term "animals" includes not only mammals like domestic quadrupeds, but also birds, fishes, reptiles, amphibians, and invertebrates such as snails, oysters, crabs, worms, sea-urchins, and jelly-fish.
Animals vary significantly in size, structure, and behaviors, adapting to diverse environments from polar regions to tropical climates.

Classification of Animals

Zoologists classify animals into groups based on physical and biological similarities and differences.
This classification is a collective effort, resulting from the work of many zoologists over time.

Major Groups of Animals

The animal kingdom is divided into several major groups distinguished by unique structural characteristics.
Vertebrates include animals with a skull and backbone made of vertebrae, such as mammals, birds, and fish.
Invertebrates are those lacking a skull and backbone, encompassing a wide variety of organisms.

Established Sub-Kingdoms

Baron Cuvier established four major groups (sub-kingdoms) of animals:
- Vertebrata: Animals with backbones.
- Mollusca: Soft-bodied animals, like snails and octopuses.
- Annulosa: Animals characterized by segmented bodies, such as annelids (earthworms) and arthropods (insects).
- Radiata: Animals with radial symmetry, like jellyfish.
A fifth group, Protozoa, includes the simplest forms of animal life, primarily composed of jelly-like substance called sarcode.
