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…

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…

Biomineralization in Mollusks and Brachiopods

The beauty of shells hides an elaborate interrelationship of structures that provides a protective layer against environmental and predatorial threats. The constant need to defend their soft body has driven mollusks to develop complex shell structures that maximize their chances of survival. This essay reviews the understanding of the process of…

Mathematical Models of Molluscan Shell Patterns and Morphology

Mollusk shells’ mesmerizing diversity of forms stems from their variations in shape, features and patterns. While these forms are highly complex and diverse, research has aimed to establish an overarching model that explains the formation of these shell characteristics. This essay explores the mathematical models that capture these natural forms…

The Biochemical Basis of Fossilization

In exceptional cases, organism remains may fossilize, persisting in sediment and retaining morphological features across great lengths of time. Eluding complete biological breakdown, these special artifacts of nature are evidence of previous life on Earth and archive the planet’s diverse history. Here, we investigate several environmental conditions which influence fossilization,…

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,…

The Mechanics and Rates of Organic Matter Decomposition

Despite their differences, living organisms find common ground when their time comes to an end. While life activities cease, the spirit of the afterlife continues in the form of decay – a critical mechanism by which an ecosystem’s nutrients and energy resources are recycled. Within nature’s ecosystems, the important task…

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…

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…
