Reptile/Amphibian Brumation

Brumation Behavior and Physiological Changes

Mackenzie Johnson

Brumation in Reptiles and Amphibians

Brumation is a specialized form of hibernation observed in reptiles and amphibians.

Brumation in Reptiles and Amphibians

It is a seasonal phenomenon characterized by a period of reduced activity, metabolism, and body temperature.

Purpose of Brumation

The purpose of brumation varies among different species.

Purpose of Brumation

Amphibians

Reptiles

Reptiles

Brumation serves as a mechanism to conserve energy and resources during the winter season. It allows them to survive in harsh weather conditions, such as extreme cold and scarcity of food.

Amphibians

Brumation serves as a form of protection against the freezing temperatures that can occur during the winter months. Their bodies have adapted to lower their metabolism and prevent ice crystals from forming in their tissues

Brumation Behavior and Physiological Changes

During brumation, both reptiles and amphibians exhibit distinct behaviors and changes. While also undergoing significant physiological changes.

Behavioral

Some reptiles may burrow underground or find shelter in crevices or rock piles. They become less responsive to external stimuli and may stay in a trance-like state for extended periods. Amphibians may also seek shelter in burrows or beneath leaf litter, where they become less active and their skin becomes thickened to minimize water loss.

Behavioral

Physiological

Physiological

Their body temperatures drop to near freezing levels, and their metabolism slows down to conserve energy. Breathing rates decrease, and heart rates slow. Blood flow to the skin is reduced, which helps to prevent heat loss. Body temperature regulation becomes less critical, as reptiles and amphibians rely on their stored energy reserves to sustain them during this period.

Brumating Species

Brumation is a widespread phenomenon observed in many species of reptiles and amphibians. Some common species that undergo brumation include snakes, turtles, lizards, and some frogs and toads. Each species has its own unique adaptations and strategies for surviving the brumation period.

Brumation vs Hibernation

Brumation and hibernation are two processes that animals undergo during the winter season. While they share some similarities, they are actually distinct physiological adaptations that help animals survive the harsh winter conditions.

Brumation vs Hibernation

Temp

Temperature:

Brumation is associated with animals that can tolerate lower temperatures, while hibernation is primarily found in animals that can survive in freezing conditions.

Duration

Duration:

Brumation is usually shorter compared to hibernation, lasting a few weeks or a few months. Most common length of brumation is between 4-5 months.

Energy

Energy Conservation:

While brumation allows animals to conserve energy, it is not as extreme as hibernation. Animals may engage in short periods of activity during brumation.

Food

Food Intake:

During brumation, animals may eat less frequently, while during hibernation, they often go for an extended period without eating.

Purpose

Purpose:

Brumation is primarily a seasonal adaptation that helps animals survive in colder climates, while hibernation is primarily a survival strategy during harsh winter conditions.

Duration and Importance of Brumation

The duration of brumation can be determined by multiple factors and the importance of brumation is critical to survival. However it is very controversial for captive pets.

Duration and Importance of Brumation

Duration

Duration

Some reptiles and amphibians brumate for months, while others may only brumate for a few weeks. The duration depends on factors such as the harshness of winter conditions, the availability of food, and individual variations in species.

Importance

Importance

It helps them cope with the harsh environmental conditions of winter and enables them to conserve energy until more favorable conditions return. Without this period of dormancy, many species would be unable to survive in cold climates.

Should captive pets go into brumation?

Should captive pet go into brumation?

Though this is a controversial topic in the vet world, most agree it is not beneficial to animals in captivity to go through brumation as we (humans) can not mimic their husbandry perfectly of which they would be in the wild. If someone wishes to have their pet go through or seems to be acting like they want to. O should bring in their pet for an exam, bloodwork, and fecal. This is to ensure the pet is not getting sick and is only showing signs of brumation.
