Reptiles - Physiology, Habitats, and Life History

This article will discuss Reptiles' physiology, habitats, body size and life history. Learn about the life history and physiology of reptiles.


Physiology of reptiles is an important study topic that focuses on the fundamental characteristics of these creatures. These animals differ in their anatomies based on their habitats and species. For example, reptiles differ in their heart structure from their conspecifics, with the venous system being more superior to the lymphatic system. Moreover, reptiles have large lungs that are essential for vocalization and display.

Unlike mammals, reptiles have smaller brains. The human brain has two large cerebral lobes. As a result, reptiles' brains are smaller in proportion to their bodies. This makes them less intelligent; which is important for survival. They also have smaller reproductive organs, such as ovaries and gonads than mammals.


Reptiles need a lot of sunlight for their biological processes, and they need a protected space to bask. They can be kept from the cold and extreme heat by providing a secure place to hide, as well as a safe, sheltered area from harsh weather. The habitat of reptiles can also provide shelter from predators, which means they need places to hide and hibernate.

Body structure

Reptiles' skins are made up of layers called dermis and epidermis. Both layers contain blood and lymphatic vessels and nerves. The dermis is under the scales, and has several other structures related to locomotion and defense. The epidermis has a dermal layer that consists of four to ten plates. This layer is responsible for the overall appearance of reptiles. 

Snakes' scales are unique to reptiles and are set up in piles. These scales cover the upper mucosal layer of the skin and the subcutaneous tissue. They protect snakes from dehydration and injuries. They help to differentiate snakes by their color and species. However, the scales aren't what makes a snake tick. Reptiles can also tell the difference between species. There is a huge difference in their physiology.

Reptiles lack specific lymph nodes and instead have discrete accumulations of lymph tissue throughout their body. This makes the snake's cloaca an important part of the body, as it is the common emptying chamber for the digestive, urinary, and reproductive systems. As for the reproductive system, snakes have paired elongated kidneys. 

Life history

The life history of reptiles is quite diverse. This diversity reveals unimaginable reproductive adaptations in reptiles. For example, some species lay a single egg or only two and mature within two years, while others lay hundreds of eggs during their lifetime. Some reptiles have evolved in such a way that their life spans can be a little more than 50 years. This diversity is remarkable. 

Sound production

Reptiles and amphibians produce a variety of sounds. Several groups produce hisses, such as anurans and geckos. Calls can exceed 90 dB SPL at one meter, and fundamental frequencies are generally over 20 kHz. Males use calls for courtship and territorial displays, while females use calls to mediate maternal care and synchronize hatching. A wide variety of species make hissing sounds, which may be useful for identification or for communication.

Research into the mechanisms of reptile sound production has been limited. The majority of reptile sound devices are associated with defensive behavior. However, some lizards use their voice to mediate group cohesion. Although reptiles have varied habitats and differing vocalization patterns, the bioacoustics of reptiles are poorly understood. So, we must rely on other sources of information to better understand the mechanisms of reptiles' sound production.
