Nature’s Nanomagnets: A Chemical Perspective on Magnetotactic Bacteria

Magnetotactic bacteria (MTB) are complex organisms that have evolved a multitude of internal chemical processes to survive their harsh environments. This paper discusses the details of important biological molecules, metabolic systems, and molecular mechanisms that contribute to the vital functions of MTB. Notably, biomineralization is a chemical, multi-step process that…

Functional Mechanics of the Elephant and Butterfly Proboscis

The trunk, also known as the proboscis, is a tubular, flexible and hollow appendage that varies in size and function; some species use it to regulate temperature, while others use it for feeding or grabbing. The purpose of this paper is to explore the biological mechanics of the movement and…

Using Mathematical Principles to Gain a Deeper Understanding of the Form and Function of Hooves

The role of ungulates’ hooves, which are morphologically complex structures, is to support body weight and provide traction to aid in their adaptation to varied external conditions. This essay aims to investigate the relationship between the mathematical model and the morphology of the hoof. The golden ratio, an irrational constant…

Spines: The Multitudes and Multi-functionalities of their Mechanisms

Abstract Many organisms possess internal defense mechanisms, intrinsic properties, and behaviors adapted for their survival. Spines and quills differ immensely across families, and this disparity exacerbates further amongst taxa. Environmental pressures such as predation and habitat unique to each species results in various physical design mechanisms for spines and quills.…

Fancy Footwork: A Morphological Study of the Role of the Hoof in Ungulate Locomotion in Habitats Around the World

In many mammals around the world, nature has designed a variable and complex structure placed at the tips of limbs called a hoof. Hoofed mammals, also called ungulates, are divided into two orders: even- and odd-toed ungulates. The divergence of these mammals from a common ancestor has led to the…

A Biochemical Review of Exoskeletal and Muscular Pincer Components and Biomimetic Applications

Abstract Pincers, or chelae, are a highly advantageous biological tool possessed by many arthropods. The chelae are useful and necessary for the survival of many species from arachnids to crustaceans. The scorpion’s pincers have a variety of purposes, including grasping and capturing prey, and deterring predators. Chelae are a highly…

A Comparison of Keratin Use in Pangolin, Reptile, and Bird Scales

Abstract Skin, a keratin-based tissue, is the largest organ in humans. This essay examines the molecular structural function of keratins, their evolutionary origins, and functions in scales and scale-derived structures.  The organisms examined are pangolins, reptiles, and birds. The hierarchical structure of keratin proteins is described for alpha and beta…

The Hormone-Dependent Regenerative Basis of Antlers

Antlers are unique architectures. They are shed and rebuilt at yearly intervals, growing from bony pedicles in early spring to full-fledged structures cast in late March. The antler growth cycle—known as antlerogenesis—is a process controlled by the fluctuating interactions of myriad hormones, mainly testosterone. The growth rate is among the…

A Biomechanical Review of Animal Tongue Functions

The animal kingdom is characterized by an astonishing diversity in tongue morphologies, functions and mechanical abilities. Through evolution, different animal tongues have adapted to perform complex mechanical functions in prey-catching and feeding in order to ensure the survival of their species. Chameleons possess the ability to ballistically project their tongues…

Jaws: Terrific yet Terrifying

Jaws are an amazing system as they can contribute to many aspects of life such as eating, defence, locomotion, etc. Each species has specific needs and thus each set of jaws tends to be adapted to fit these demands. In the animal kingdom, some jaws show unique characteristics, which not…
