Intro to Zoology

1. Intro to Zoology

2. Zoology is the study of the entire animal kingdom • zo- {New Latin} = animal; • -ology = study of, knowledge • Zoology is a subset of Biology • C. One of the broadest fields in all of science 20,000 known species of bony fishes 300,000 known species of beetles

3. All members of the Kingdom Animalia are multicellular, eukaryotic, heterotrophic organisms.

4. Invertebrate zoolgyis the study of multicellular animals without backbones. • Entomology - study of insects • Myrmecology - study of ants • Apiology - study of honey bees • Arachnology - study of spiders and their relatives • Malacology - study of mollusks • Conchology - study of mollusk shells

6. Vertebrate zoology is the study of animals with backbones. • Ichthyolgy - study of fish • Herpeteology - study of amphibians and reptiles • Ornithology - study of birds • Mammalogy - study of mammals • Cetology - study of marine mammals • Primatology - study of primates

8. Embryology- study of development • Parasitology- study of diseases • Morphology - study of the shape, form, and structure of animals and their parts.

9. Comparative anatomy is the study of the similarity and differences in the anatomy of different groups of animals. • Structures are homologous if they have arisen from the same ancestral structure, but perform either similar or different functions in modern animals. Examples are the wings of birds, the human arm, and the forelimb of whales.

10. Homologous Structures

11. Comparative Anaomy • Analogous structures have developed from different ancestral structures, but perform similar functions. Examples are the wings of birds and the wings of insects.
