The Physical Adaptations Underlying the Tardigrade’s Resistance to Extreme Environmental Conditions 

Although tardigrades were discovered in the late 18th century, they have continued to captivate scientists due to their outstanding resistance to environmental conditions that are lethal to most organisms and that is necessary given their ecological distribution across various environments. Explanations as to the mechanisms underlying this superior resistance have…

A Chemical Review of Animal Tongue Functions

In the animal kingdom, the evolution of tongue morphology has facilitated the survival of many species by providing advantages in foraging, avoiding predators, prey-catching and discriminating between food sources. Some species, notably the family of squamates, have developed impressive foraging strategies through the interpretation of chemical cues from their environment…

Functional Interpretations of Chemotaxis in Migrating Organisms

There are many functional applications of chemotaxis that form the stepping stones of animal migration. Investigating trophic chains – dynamic networks of interacting species – reveals how migration and changes in population density shift environmental conditions of an ecosystem. It was shown how fish and algae populations can reduce extinction…

Biological Design for Lungs and Gills: Information and Storage Processing

This report describes two of the most important gas exchangers for all living animals: lungs and gills. Throughout the research, cutaneous respiration will also be explained; however, the most efficient oxygen diffusion rates are obtained through lungs and gills, which are our main concern. The purpose of this biological design…

An Analysis of Sensors and Systems of Artificial Noses

In the past couple decades, the field of artificial organs has seen immense progress, such as more comfortable prosthetic limbs and artificial livers. However, in recent years, a need for a technology able to detect the presence of molecules that the human nose cannot has emerged, leading to the creation…

The Biomolecular Design of the Eye

In “The Optical Properties of Camera Eyes” the optical properties of the camera-type eye and how light can properly converge light onto the retina to endow an organism with a clear picture of its surroundings were discussed (Gedik et al., 2020). To summarize, the camera eye of many animal species…

Biomolecular Factors for Immunity, Color Change, and Mechanical Strength of the Integument

The skin is a highly complex organ. It contains many components which allow it to fulfil its functions. These components include various cells and proteins which are regulated by intricate biological pathways. Across different organisms, there is a large variety of these components, which exist at several levels of complexity and…

Healing, Mechanical Loading, and Water-harvesting with Integument Structures and their Biomimetic Applications

This report focuses on the structures that enable healing, mechanical loading, and water-harvesting of the integument (i.e., skin, feathers, hair, scales, etc.). By examining the morphologies that allow for these functions, and detailing their interrelation, we develop a basis for understanding how an organism’s design is related to its operation.…

Mechanical and Material Design Principles of the Avian Egg Shell

The design of the avian egg presents intricacies ranging from its mechanically durable architecture to its composition of bacterial protective materials. Characteristics such as the function, architecture, operation, and eggshell vulnerabilities are presented to outline the success of embryo survival and chick pipping. Protection against various external conditions and the…

Functions of the Gut through the Perspective of Biological Mechanics

The main functions of the gut are to digest food, absorb nutrients, and to eliminate waste. These functions vary between species, causing different guts to have different structures. Natural selection has determined the structure of different guts by what the animal consumes, where they live, and how other parts of…
