Relationship between an animal's nervous system and its behavior.

Grzimek’s Encyclopedia of Ethnology delves into the fascinating world of animal behavior, with a significant focus on the role of senses in shaping that behavior. Grzimek’s Encyclopedia of Ethology offers a valuable window into the world of animal senses. There are four portions about the sense in this book namely The Visual Sense, the Mechanical Sense, The Chemical Sense, and The Electrical Sense.  This portion explores key senses fundamental to animal life.


The text emphasizes the diversity of vision across the animal kingdom. While some creatures, like primates and birds, possess excellent acuity for navigating their environment, others, like insects, have compound eyes that provide a wider field of view.

The encyclopedia highlights how adaptations like nocturnal vision in owls or the ability to see ultraviolet light in bees play crucial roles in survival and foraging.

Chemical Senses

Smell and taste, grouped under chemical senses, are explored in detail. Grzimek’s Encyclopedia emphasizes the significance of these senses in communication and social interactions. Pheromones, chemical signals released by animals, are a prime example. They can signal mating readiness, territorial boundaries, or even danger to others.


The text also discusses the impressive olfactory abilities of some animals, like bloodhounds renowned for their tracking prowess.

Mechanical Senses

Touch, pressure, and balance are encompassed within mechanical senses. The text highlights the presence of mechanoreceptors throughout an animal’s body, which allows them to sense their environment. From the sensitive whiskers of a cat to the lateral lines of fish that detect water movement, these receptors provide vital information for navigation, hunting, and avoiding predators.

The role of proprioception, the ability to sense one’s body position, is also explored, emphasizing its importance in coordinated movement.

Electrical Senses

A lesser-known sense covered in the encyclopedia is the electrical sense. This ability, found in some fish and sharks, allows them to detect weak electrical fields generated by other animals. This information can be used for navigation, particularly in murky waters, or to detect prey hidden beneath the sediment.

Grzimek’s Encyclopedia sheds light on this fascinating adaptation, showcasing the remarkable ways animals perceive their surroundings.

Grzimek’s Encyclopedia also acknowledges the existence of additional sensory abilities in certain species. For instance, some birds possess magnetoreception, allowing them to navigate using the Earth’s magnetic field. The text highlights the ongoing research in animal senses, hinting at the potential discovery of even more unique sensory capabilities. This understanding is crucial for appreciating animal behavior and the intricate adaptations that have allowed them to thrive in a multitude of ecosystems.


There are two specific entry on neuroethology present in Grzimek’s Encyclopedia of Ethology, the field itself is highly relevant to the overall theme of the encyclopedia.  Grzimek’s Encyclopedia focuses on ethology, the study of animal behavior in their natural environment. While the term “neuroethology” wasn’t as widely used in the 1970s, the encyclopedia likely laid the groundwork for this emerging field.

Neuroethology bridges the gap between ethology and neurobiology. The encyclopedia likely explores various aspects of animal behavior, like:

Sensory Perception

It might discuss the structure and function of sensory organs (eyes, ears, nose) and how they translate information into neural signals.

Behavioral Responses

The book could explore how these neural signals trigger specific behaviors like hunting, mating, or escaping predators.

Nervous System Structure

Sections on the nervous system (brain, spinal cord) might provide a foundation for understanding how information processing occurs.

Examples from the Book:

Imagine the encyclopedia’s entry on echolocation in bats. It might describe the intricate structure of their auditory system and how it captures and interprets sound waves. This paves the way for neuroethology, which would delve into the specific neural pathways that translate these echoes into a “map” of the bat’s surroundings.


Similarly, the book might discuss animal communication through pheromones or visual displays. Here, neuroethology would explore how the nervous system detects and interprets these signals, triggering specific behavioral responses.

Social behavior of the animal

Grzimek’s Encyclopedia of Ethnology delved into specific aspects of animal behavior. Readers could explore topics like communication, with sections dedicated to how animals use vocalizations, body language, and even chemical signals to interact with each other.


This Encyclopedia delves into the fascinating interplay between genetics and social behavior in animals. It explores how inherited traits and environmental influences shape the way creatures interact with each other.


The encyclopedia highlights the concept of instinct, a set of genetically determined behaviors. These instincts guide essential activities like migration, foraging, and reproduction. For instance, birds possess an innate ability to navigate long distances during migration, a behavior encoded in their genes.


However, Grzimek’s Encyclopedia emphasizes that genetics isn’t the sole player. Social learning plays a crucial role in shaping behavior. Animals learn from observing and interacting with others, particularly their parents or elders. This cultural transmission allows for the refinement of behaviors and the development of complex social structures.


The encyclopedia cites examples like young chimpanzees’ learning tools used by observing adults. They refine their technique through trial and error, demonstrating how social learning builds upon inherited predispositions.


Furthermore, Grzimek’s Encyclopedia explores the concept of kin selection, where animals behave in ways that benefit their close relatives, even if it means sacrificing their well-being. This altruistic behavior ensures the survival of genes shared within a family group.


In conclusion, Grzimek’s Encyclopedia of Ethology paints a comprehensive picture of the intricate dance between genetics and social behavior. It recognizes the role of instincts but highlights the significance of social learning and kin selection in shaping the fascinating world of animal behavior.

Deeper appreciation for the natural world

Grzimek’s Encyclopedia of Ethology wasn’t just a dry collection of facts. The editor, Bernhard Grzimek, was a passionate advocate for wildlife conservation. The book subtly wove in themes of the importance of understanding animal behavior for conservation efforts. By highlighting the complex social structures and unique behaviors of different species, the encyclopedia encouraged a deeper appreciation for the natural world and the need to protect it.


While published in the late 1970s, Grzimek’s Encyclopedia of Ethology remains a valuable resource for those interested in animal behavior. It provides a strong foundation in the core concepts of ethology and offers a glimpse into the fascinating world of animal communication, social interactions, and the intricate link between an animal’s biology and its actions. The book serves as a testament to the tireless work of ethologists and the enduring legacy of Bernhard Grzimek’s passion for the natural world.
