Брумација је рептилски еквивалент хибернације, то је, тај временски период током којег животиња успорава сопствени метаболизам и престаје скоро сваку активност да би сачувала енергију и преживела зиму.
У дивљини, тегус ће се повући у безбедан простор да би се сакрио када дани почну да се скраћују у јесен и тамо ће остати 6-7 месеци until spring arrives.
During this period of brumation a tegu will sleep a lot and not eat any food, and barely drink any water.
Do tegus need to brumate?
У заробљеништву, tegus do not necessarily need to undergo brumation.
In the absence of the conditions that trigger hibernation (shorter day cycles, lower temperatures) within the enclosure, a tegu will simply keep being active, feeding and growing.
У ствари, tegus that do not brumate tend to grow larger in size compared to those who do.
The only potential health concern when it comes to skipping brumation is a potential impact on fertility.
This is a concern especially for females as there is growing evidence that not letting them undergo brumation in the first two years of life may lead to infertility and increased risk of becoming egg-bound.
There is still limited research on brumation and the effects it (or lack thereof) has on tegus, but to be on the safe side: if you are planning to breed tegu lizards, it is better to let them undergo brumation especially when they are young and still maturing.
How to induce brumation
The best way to encourage your tegu to go into brumation is to set up a living environment which resembles its natural habitat and especially the changing of seasons.
There is a misconception that tegus brumate when it is winter because temperatures are colder, but this is actually not the case.
Brumation seems to be triggered by a combination of environmental factors and reduced daylight is what seems to have the greatest impact.
To induce brumation, try gradually reducing the amount of time your lights are on in the enclosure, set up the timer to 8 hours instead of 12, if you have multiple lights start shutting them off entirely one by one.
Once the tegu goes to sleep, you can actually shut all the lights off for the rest of winter, saving on energy bills is actually one of the main “perks” of brumation for tegu owners.
Температура
During winter you can lower temperatures to around 55°F – 70°F (13°C-21°C). Lower temps alone will not induce brumation, but if your tegu is hibernating it can help to keep the enclosure cooler to aid slowing their metabolism as they would in winter.
How to care and feed your tegu during brumation
When a tegu starts showing the first signs that they are about to go into brumation, they will gradually become less active, sleeping a lot and spending time in their cage more than usual.
You should keep offering them food regularly at this time but you will notice that they will start refusing to eat – do not insist.
Start lowering the lights and offering food less often until the tegu retreats to their hide to hibernate.
At this point, they will basically sleep for months and do not need light nor food. You should keep a bowl of fresh water available but most likely they won’t drink any.
The tegu may wake up and come out every now and then, in this case you can try offering some food and see if they accept it, most likely they will go back to sleeping right after.
Remember that a tegu can go months without eating in winter, so do not be alarmed.
Do not leave any uneaten food in the enclosure for more than a couple of hours.
Coming out of brumation
There is no way to artificially stop or shorten brumation.
Tegus will naturally start becoming more active as they come out of brumation, waking up and leaving their hide more often for basking.
У овој фази, it is too soon to start offering them food again, but make sure to keep fresh water available to them.
Monitor your pet for a couple of weeks, during which they will either go back to sleep or become more and more active.
In this case, you can start reintroducing food to them gradually and turn the light back on a 12 hours on/off schedule.
Tegu Brumation FAQs
What is tegu brumation?
Tegu brumation is the reptile equivalent of mammalian hibernation, a period of dormancy that helps tegus conserve energy and survive the winter months.
During brumation, tegus will become less active and eat less. They may also lose weight. Some tegus may even bury themselves in their substrate.
What triggers brumation?
The primary trigger for brumation is the shortening of days. Међутим, other factors such as changes in temperature, влажност, and atmospheric pressure can also play a role.
У дивљини, tegus use the shortening of days to know when it is time to start preparing for winter.
У заробљеништву, tegus may brumate even if they are kept in a warm environment, as long as the days are short enough.
Do all tegus need to undergo brumation?
Не, not all tegus need to undergo brumation.
Captive tegus that are kept in a warm and well-lit environment may not brumate at all.
Међутим, brumation is a natural process that is important for tegus, and it can help to improve their overall health and lifespan.
What are the signs that my tegu is getting ready to brumate?
Some of the signs that your tegu is getting ready to brumate include:
- Decreased activity
- Decreased appetite
- Weight loss
- Sleeping for longer periods of time
- Seeking out cool, dark places to hide
When does brumation start?
Tegus typically start to brumate in the fall, when the days get shorter and the temperature drops, but the exact timing can vary depending on the individual tegu and the climate.
How long does brumation last?
Brumation can last anywhere from 4 до 7 месеци, but some tegus may even brumate for longer periods of time in cooler climates that have longer winter periods with short days.
Can you stop brumation?
It is not possible to completely stop a tegu from brumating, but you can try to delay the onset of brumation by providing your tegu with a warm and well-lit environment and increasing the amount of food that you offer.
Your best bet if you want to prevent your tegu from going into brumation is the amount of light you offer throughout the day in winter.
How do you care for a tegu during brumation?
Here are some tips on how to care for a tegu during brumation:
- Make sure that your tegu has a cool, dark place to brumate, with a temperature between 50 и 60 degrees Fahrenheit.
- Reduce the amount of food that you offer your tegu during brumation, but still offer small meals every few days.
- Make sure your tegu has access to fresh water at all times.
- Monitor your tegu’s weight and condition during brumation, and consult with a veterinarian if you are concerned about your tegu’s health.
- Provide your tegu with a humid environment, and mist the enclosure regularly if needed.
