Study Notes

Introduction to Zoology

Zoology is the study of animals, encompassing their structure, physiology, development, evolution, classification, distribution, behavior, and ecology.
Animal diversity is vast and encompasses a multitude of species.

Animal Classification

Animals are categorized into phyla based on shared characteristics.
Classification criteria include body symmetry, tissue layers, body cavity, segmentation, and appendages.
Major animal phyla include Porifera (sponges), Cnidaria (jellyfish), Platyhelminthes (flatworms), Annelida (segmented worms), Mollusca (mollusks), Arthropoda (insects, crustaceans), Echinodermata (sea stars), and Chordata (vertebrates).

Animal Structure and Function

Animals display various structural adaptations, often linked to their lifestyles.
Adaptations include specialized respiratory (lungs, gills), digestive, and excretory systems, tailored to dietary needs and habitats.
Animal cells are eukaryotic and form tissues, organs, and organ systems.

Animal Behavior

Animal behavior encompasses actions and responses to the environment and other organisms.
Behaviors can be innate (instinctive) or learned.
Studying animal behavior provides insights into cognition, social interactions, and survival strategies.
Examples include foraging, mating, communication, and predator-prey relationships.

Animal Ecology

Animal ecology examines the relationships between animals and their environment.
This includes interactions with other species, resource availability, and abiotic factors like temperature and rainfall.
Ecological niches define a species' role within an ecosystem.

Animal Evolution

Animals evolved from simpler organisms over millions of years.
Fossils provide insights into evolutionary relationships and patterns.
Natural selection shapes animal characteristics over generations.
Phylogenetic trees visualize evolutionary relationships.

Animal Diversity

Animal diversity encompasses the extensive array of animal species.
Diversity includes variations in form, function, and behavior.
Conservation efforts are critical for maintaining animal biodiversity.

Animal Physiology

Animal physiology investigates how animals function at cellular, organ, and organismal levels.
Topics include metabolism, respiration, circulation, and reproduction.
Understanding animal physiology is key for studying animal health, disease, and conservation.
Physiological adaptations help animals thrive in various environments.
