Underwater Chemists; Discussion of Design Solutions in Tintinnid Ciliates

In this essay we explore tintinnids’ intricate design solutions through the lens of chemical processes and pathways, emphasizing the vital role chemistry plays in their survival. These ciliates employ complex chemical processes that regulate digestion, reproduction, self-protection, and swimming mechanisms. We explore the cell and life cycle of tintinnids, their…

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…

Proboscis Geometry, Allometry and the Mathematical Beauty of Spirals in Nature

Abstract The proboscis has many functions, notably feeding and mating, making it an incredibly useful organ. This paper aims to explore its structure and study the type of relationship between its components, called an allometric relationship. Allometry also appears when studying  how changes in structure affect some functions of the…

An Evolutionary Analysis of the Chemical Composition of Marine Suction Cups

Abstract Suction cups are important adaptations for aquatic animals, allowing for predation, locomotion, stability, and other species-specific functions. The chemical structure of each suction cup is designed by nature to be as energetically efficient as possible in performing the suction cup’s species-specific purpose, giving the suction cup chemical properties that…

Courtship and Mating: The Chemistry of Pheromones and Their Evolutionary Function

In this essay we investigate the chemistry involved in the reproductive process. Courtship and mating practices are not limited to physical and auditory pursuits. Pheromones cause innate chemical allurement between compatible animals. There are a wide range of pheromones, and each have their own specific properties and functions. Different pheromones…

Regulation of the Gut and its Effect on Animal Behavior

This paper explores how neurotransmitters, chemical signals, and the enteric nervous system regulate this impressive organ. It then follows with an extensive account of how the gut microbiome influences social groups, recognition cues, and mating preferences among animals. Finally, acting as complementary sections for “Stable Isotopes and Diet Analysis: Insight…

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…
