A Physical Analysis of Magnetotactic Bacteria: Nature’s Microscopic Compass as a Solution to a Motile Biotope

Figure 1: Magnetotactic Bacteria (Perduca, 2016). Magnetotactic bacteria (MTB) are unique aquatic microaerophiles that can align and move in the direction of the Earth’s magnetic field. In this paper, the basic physical properties of magnetosomes, some mechanisms, such as magnetotaxis, and phototaxis, involved in the MTB’s motion, and the role…

Frustules: Design solutions in Diatoms

There are many microorganisms in the universe, and they can generally be sorted into three types: prokaryotic, eukaryotic, and acellular. The subject of this paper is a member of the eukaryotic family, and they are commonly present in nature: the diatom. The diatomite which is formed by the death of…

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…

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.…

Biomechanics of Marine Suction Cups and Applications to Artificial Suction Technology

Suction cups are important adhesive adaptations for many marine animals, allowing for locomotion, predation, stability, and grasping of objects. Interesting morphological adaptations have allowed the suction cups of distinct species to best accommodate the purpose of the suctioning mechanism as well as the unique environment that the organism inhabits. The…

The Hydrodynamic Advantages of Shark Scales

This essay examines the drag-reductive properties of sharks’ scales and analyzes the macroscale and microscale structures and mechanisms that diminished turbulence for the fish in motion over the course of evolution. Fluid dynamics theory and Reynold’s number are used to explain the high reduction of turbulence and friction drag in…

Mathematical Modeling of Animal Tongues

Mathematical modeling of animal tongue functions has improved the understanding of the animal kingdom and how species have evolved to efficiently perform tasks necessary for their survival. The chameleon can rapidly project its tongue, achieving large extension distances due to energy storage within the geometric structures of their tongues. This…

A Biochemical Analysis of Mammalian Milk: Diversity Amongst Species and Biomedical Applications

Lactation is a natural phenomenon that unifies the mammalian class and serves the fundamental purpose of supplying offspring with the essential nutrition and immune protection for survival in the early stages of life.  Despite the existence of physiological diversity across lactating species, the general biochemistry of mammalian milk is a…

A Neurochemical Overview of Sleep, its Deprivation and Hibernation

The phenomenon of sleep has been universally observed among animals, and is driven by a plethora of chemical processes that regulate the animal’s brain activity. The onset of sleep brings about a number of chemical changes driven by various neurotransmitters. These changes allow the brain to carry out and improve…

Chemical Adaptation in Viviparous Birthing and Oviparous Hatching

One of the first stages of life in any animal is time spent as a developing embryo. Every embryo must undergo complex development aided by its parent for a certain period of time before their birth or hatching, and this process varies greatly depending on the type of species. Specifically,…

Bioinformatics and Sensory Function of Mammalian Fur: An Analysis of Coat Patterning, Whiskers, and Trigger Hairs

The Turing pattern, which is further explained in the paper, is an observed pattern in natural systems ranging from cheetah print to coral growth. Alan Turing proposed a mathematical model to describe pattern formation based on reaction and diffusion rates of morphogens, and this model holds true for a vast…

Cephalopods and their Beak

From ants to elephants — and passing through sea cucumbers, adaptations in the animal kingdom are majestically diverse. For instance, means of travel include legs, more legs, wings, flippers and suction cups. Bodies can be scaled, slimy, furry, feathered, spiky, or armored and the list goes on. Basic feeding can…
