This book offers a structured and scholarly introduction to the fundamental principles of animal psychology, examining how mental processes and behavioural responses develop across a range of animal species. It explores the psychological basis of survival-oriented behaviour, sensory perception, learning, and adaptation in diverse ecological contexts. The discussion emphasises how animals interpret their environments through specialised sensory systems and how these perceptions influence movement, communication, and behavioural decision-making. By drawing on comparative studies, the book highlights variation in behavioural patterns among terrestrial and aquatic species, demonstrating how psychology and physiology work together to shape behaviour. Attention is also given to instinctive and learned behaviours, illustrating the role of cognition, memory, and environmental interaction in shaping complex behavioural responses over time.

The book also focuses on applied perspectives in animal psychology, linking behavioural understanding with animal welfare, conservation, and habitat management. It considers how psychological insights support ethical treatment, improved environmental design, and species-specific care strategies. Written in a formal UK academic style, the book is intended for students, researchers, and practitioners seeking a clear and international-level understanding of animal psychology and its relevance within modern biological and behavioural sciences.
