Tarantulas have many interesting behaviors. If you ever wondered whether they hibernate, the answer is technically yes. This is because tarantulas do not actually hibernate but enter a hibernate-like state. In this article, we explore the answer to the question: do tarantulas hibernate?
Can Tarantulas Hibernate?
Tarantulas exhibit periods of inactivity that resemble hibernation, but it’s not technically the same. Instead, they enter a state akin to torpor or diapause, characterized by reduced metabolic activity and slowed movement. During this time, they conserve energy and endure harsh environmental conditions. While not true hibernation, this behavior helps tarantulas survive unfavorable circumstances. Among spider behaviors, this falls under a type of inactivity.
Types of Spider Inactivity
In the world of spiders, periods of inactivity vary and are crucial to their survival. Here’s a breakdown of the different terms used to describe their behavior:
Hibernation: This is a seasonally driven reduction in metabolic and body activity, often occurring in colder months. It involves maintaining low body temperature, minimal breathing, and a slow heart rate, allowing animals to conserve energy reserves.
Diapause: Diapause is an active phase of inactivity wherein growth and development stall due to unfavorable environmental conditions. It is genetically predetermined and effectively suspends the organism’s progress until conditions improve.
Torpor: A state of reduced metabolic rates and physical inactivity, which can occur daily or over an extended period. Unlike hibernation, animals in torpor may awaken briefly to feed or drink before returning to their inactive state.
Brumation: This term applies specifically to cold-blooded animals and describes their inactive periods. During brumation, these animals remain inactive for long stretches, occasionally waking to drink water.
Aestivation: Similar to hibernation, aestivation involves reduced metabolic rates and activity, but it occurs in response to hot and dry weather conditions.
Understanding the distinctions between these terms offers insight into the diverse strategies spiders use to cope with environmental challenges, despite their frequent interchangeable use.
Which Inactivity Do Tarantulas Fall Under?
Tarantulas, like other spiders, lack the ability to regulate their body temperature since they are cold-blooded. This inability to control their internal heat means they face challenges when exposed to extreme environmental conditions, such as excessive heat in a tank.
Unlike animals capable of hibernation, which involves temperature regulation among other factors, tarantulas cannot truly undergo this state. Instead, their periods of inactivity more closely resemble diapause, torpor, or brumation. However, there’s no definitive consensus on the correct term for tarantula dormancy, leading to the interchangeable use of these terms in practice.
Tarantula Species that Hibernate and Why
Certain tarantula species, like the Aphonopelma chalcodes and Brachypelma albopilosum, have been noted to undergo hibernation. This state of dormancy enables them to conserve energy and endure adverse environmental circumstances. Some common reasons behind this dormancy include:
- Energy conservation: Hibernating tarantulas lowers their metabolic rate, saving energy for prolonged periods, it is crucial for enduring food scarcity in winter.
- Temperature regulation: These tarantulas choose burrows or crevices with stable temperatures, maintaining a suitable microclimate, especially in colder regions.
- Mating habits: Tarantulas synchronize their reproductive cycles with hibernation, ensuring readiness for mating upon emergence, and optimizing reproductive success.
- Hibernation studies: Extensive research on tarantula hibernation sheds light on physiological changes during this period, offering insights into survival adaptations in challenging environments.
What do Tarantulas do During Winter?
Hibernation is usually associated with winter, so what do tarantulas do in this season? During winter, tarantulas undergo changes to adapt to colder temperatures and reduced food availability. Unlike some spider species that enter a hibernation-like state called cold-hardening, tarantulas don’t hibernate in the same way. Instead, they seek shelter in burrows, sealing entrances with soil and debris to stay warm.
Their metabolism slows down gradually to conserve energy, increasing their chances of survival during winter months. Tarantulas naturally have low activity levels, but when temperatures drop below 65°F, they become even less active and may stop eating, effectively entering a form of hibernation. Notably, their hibernation behavior is triggered by ambient temperatures rather than the time of year, meaning they can enter this state even in summer if conditions are cold.
Do Tarantulas Hibernate in Captivity?
Tarantulas rarely hibernate in captivity, typically only if temperatures drop too low for them to function. This occurrence is infrequent due to two primary reasons. Firstly, the temperatures maintained in captivity are generally high enough to keep tarantulas active year-round, provided their environment remains adequately heated.
Secondly, unlike in the wild where environmental cues prompt hibernation, tarantulas in captivity don’t experience the same triggers, such as food scarcity, prompting them to reduce metabolic rates.
To prevent hibernation in pet tarantulas, it’s crucial to maintain temperatures above 70 degrees Fahrenheit (around 20 degrees Celsius) and ensure they receive sufficient food to maintain their metabolic systems. Essentially, by maintaining proper care and suitable temperatures, pet owners can effectively prevent tarantulas from entering hibernation in captivity.
Caring for a Tarantula During Hibernation
Caring for your tarantula during hibernation is essential for its well-being and safety. While tarantulas don’t require hibernation to survive, if you choose this option, it’s vital to take precautions and dispel myths. Firstly, ensure a suitable hibernation environment, with temperatures between 50 to 60 degrees Fahrenheit and proper ventilation to maintain humidity levels around 70 to 80 percent.
Secondly, refrain from feeding your tarantula during hibernation to prevent digestive issues, resuming feeding only after it fully emerges. Lastly, avoid disturbing your tarantula while it hibernates to prevent stress and potential harm during its dormant state.
Conclusion
In conclusion, tarantulas do enter a form of hibernation. The state is a combination of different types of inactivity and results in reduced metabolic activity and slowed movement. This generally happens with wild tarantulas mainly because of energy conservation and temperature regulation. If your tarantula shows signs of going into hibernation at home, there are ways to care for them. So, to answer the question, do tarantulas hibernate? The answer is yes.
