Animal Biology

Animal biology, also classified as zoology, is a field of study which examines the animal kingdom, including both invertebrates and vertebrates. This discipline of animal biology is not limited to focusing solely on living species, but also organisms which have gone extinct.

Animal biology is a scientific field which is interconnected with many other scientific disciplines. For example, the areas of evolutionary biology, paleontology and molecular biology are closely related fields. Evolutionary biology examines the progression of animal species overtime from primitive organisms to rather complex beings. Paleontology assists evolutionary biologists through the discovery of fossil evidence. Additionally, molecular biology highlights how the genetic mechanisms which underlie different animal species allow them to function.

More specifically, animal biology focuses on learning the anatomy and physiology of animal species, animal behaviour and the comparative biology between different animal classes, such as fish and insects. In terms of animal anatomy and physiology, this involves comparing and contrasting how systems such as the respiratory and nervous systems function in various species. Animal behaviour is a very broad subject which mainly focuses on the ways in which animals act in their native environments.

Animal biology is an expansive topic which is very interdisciplinary with other fields of biology. Understanding animal biology is critical in helping society better comprehend the animal world and realize the diversity which exists. Hopefully, through studying animal biology individuals will gain an appreciation for species diversity and be motivated to try and conserve these priceless resources.

Animal Behaviour

Postings: 3

Animal behaviour can be defined as the study of how different species act in their natural environment, in terms of interacting with each other, with individuals of different species and the physical actions they exhibit to survive.

Insect Anatomy and Physiology

Postings: 6

Insects are invertebrates which have an external and internal anatomy which is structured and functions widely differently from vertebrate species.

Fish Anatomy and Physiology

Postings: 4

Fish are aquatic species which display a large range of diversity due to the vast array of habitats which they can survive in from streams found in high mountains to habitats in the deep ocean.

Does sky blue paint keep wasps from building nests?

Your neighbor added a farmer's porch to his house and painted the ceiling of it blue. When you asked him why, he told you he had read that the sky blue ceiling would fool wasps into thinking it was the sky and they would not build any nests under the eaves of the porch or along the ceiling. Would a blue ceiling really deter was
