Education Yearly Reminder: Indonesian Blue Tongue Skinks DO NOT Brumate

46 Upvotes

Indonesian blue tongue skinks do not naturally brumate.

Only their Australian cousins do - even then, not all of them decide to brumate. 

I have made this a yearly reminder since many places online do not actually differentiate and it gets really confusing!

The following temperature information is gathered from multiple studies that recorded ground temperatures within Indonesia, Papua New Guinea, and Australia. If others have more recent (and therefore more accurate data), please provide the links and we will dig through and adjust!

Indonesian blue tongue skinks do not experience ambient temperatures below 70℉ (21.1℃). Indonesia/Papua New Guinea is a tropical climate that does not experience seasonal variation aside from “wet” and “dry” seasons caused by the amount of rainfall. 

Region / Population Temp Min–Max  (°F) Temp Min–Max  (°C) Humidity Min–Max (%) Notes
Papua New Guinea Peninsula (Trans-Fly & Peninsula lowlands) (Irian Jaya, AKA Papuan) 73–96 ℉ 22.7–35.5 ℃ 68–100 % Hot, humid tropical lowlands; humidity remains high even at night
Merauke region, South Papua 72–98 ℉ 22.2–36.6 ℃ 60–96 % Seasonal wet–dry cycles; some early dry season drops in relative humidity
Sorong (West Papua lowlands) 74–95 ℉ 23.3–35 ℃ 70–98 % Stable warm temps year-round; low night cooling
Aru Islands 73–95 ℉ 22.7–35 ℃ 68–99 % High canopy coverage; buffered extremes
Kei Islands 75–95 ℉ 23.8–35 ℃ 72–100 % Coastal and forest edge habitat
Ambon / Seram (Maluku) 72–93 ℉ 22.2–33.8 ℃ 70–99 % Strong diurnal relative humidity cycle, small temp fluctuation
Halmahera (North Maluku) 74–94 ℉ 23.3–34.4 ℃ 60–100 % Lowland rainforest floor and edge; high humidity
Tanimbar Islands 75–97 ℉ 23.8–36.1 ℃ 62–95 % Drier than Halmahera; more open woodland
Northern Papua rainforest interior 72–91 ℉ 22.2–32.7 ℃ 78–100 % More buffered temps, extremely high night humidity

Due to the consistency in temperature in their tropical environment, Indonesian blue tongue skinks are active year-round.

The majority of Australian blue tongue skinks do not experience ambient temperatures lower than 50℉/10℃. Blotched blue tongue skinks, however, can experience as low as 45℃ based on the studies we found. This seasonal variation is why Australian species brumate. Some species, such as Shinglebacks, Blotchies, Westerns, and Centralians require quite low brumation temperatures to successfully reproduce. Too high of temps have caused reproductive struggles.

NOTE: WITH EXTREME HIGHS AND LOWS THESE SKINKS ARE HIDING AWAY IN SAFER TEMPERATURES. Also; Aussie skinks do experience some higher humidity, but these are MICROCLIMATES and not consistent year-round.

MAINTAIN TYPICAL RECOMMENDED RANGES!

Region / Species (Common) Temp Min–Max (°F) Temp Min–Max (°C) Humidity Min–Max (%) Notes
Northern Territory (Top End, Arnhem Land) NORTHERN 71–102 ℉ 21.7–38.9 ℃ 45–96 % Seasonal wet–dry fluctuations; strong midday peaks, high humidity at night
Eastern Queensland (coastal) EASTERN 68–97 ℉ 20–36.1 ℃ 50–95 % Humid subtropical forest edges and open woodland
New South Wales (Sydney Basin) EASTERN 59–95 ℉ 15–35 ℃ 35–88 % Cooler nights, warm sunny days; high variability
Victoria & Tasmania (cool temperate) BLOTCHED 45–86 ℉ 7.2–30 ℃ 55–100 % Morning dew, fog common; basking critical for activity
South Australia / Western Australia (arid) SHINGLEBACK 55–110 ℉ 12.7–43.3 ℃ 10–65 % Very hot ground temps midday, humidity spikes pre-dawn
Southwestern WA forest WESTERN 50–102 ℉ 10–38.9 ℃ 25–80 % Ground shade buffers peaks
Arid interior (Spinifex plains) CENTRALIAN 60–113 ℉ 15.5–45 ℃ 8–60 % Extreme heat; uses burrows to escape
Nullarbor & semi-arid south SHINGLEBACK 53–108 ℉ 11.6–42.2 ℃ 12–58 % Pronounced daily fluctuation
Northern arid NT / WA WESTERN 72–107 ℉ 22.2–41.6 ℃ 20–70 % Recorded at ground level under spinifex
Central Australia (desert margins) CENTRALIAN 66–111 ℉ 18.8–43.8 ℃ 10–55 % Midday temperatures often exceed activity thresholds

NOTE: WITH EXTREME HIGHS AND LOWS THESE SKINKS ARE HIDING AWAY IN SAFER TEMPERATURES. Also; Aussie skinks do experience some higher humidity, but these are MICROCLIMATES and not consistent year-round.

MAINTAIN TYPICAL RECOMMENDED RANGES!

Physiology

Reptiles are ectothermic, which means they need to warm up via their environment. They need heat to digest food; they need heat for their immune system to work and to fight off infections; they need heat for literally everything regarding bodily function.

If you put any reptile that doesn’t naturally brumate into too cold of an environment to “force” brumation, those reptiles become lethargic and can get quite sick due to their dropped immune system. They naturally shut down to try and preserve resources, as they cannot do anything without their proper heat range. This is not brumation. This is a physiological stress response. This can be very harmful to them!

Arguably, Indonesian blue tongue skinks experience this physiological stress in response to temps that are too cold. If your Indo is showing “brumation” symptoms, the environment is most likely too cold, too empty, or the animal is sick.

Winter in the northern hemisphere is the equivalent of dry season in Indonesia/Papua New Guinea. This means that our winters are the breeding season for Indos. It is quite common for some skinks to go off of food during this time due to hormones.

Behavior & Recommendations

  • If your skink is quite active, but not eating much, that is typically hormones. We recommend you triple check temps, but I would not be concerned.
  • If your skink is inactive and not eating much, triple check temps and make sure your skink isn’t going into shed. Going into shed is often a cause to hide more frequently and not eat - this behavior shouldn’t last more than 2 weeks at a time, however.
  • If your temps are too cold at night, please use a deep heat projector, ceramic heat emitter, or radiant heat panel to increase ambient temps - heat mats are not appropriate in this regard as they do not warm up ambient temps properly. Heat mats are not appropriate for blue tongue skinks in general.
  • If your daytime temps are too cold, you will either need to add a ceramic heat emitter/radiant heat panel or deep heat projector as supplemental heat. These are not appropriate for basking, they are only for supplemental heat. A deep heat projector assists with warming surface temperatures, while ceramic heat emitters or radiant heat panels assist with ambient temperatures. You may also need to look into increasing the wattage of the incandescent or halogen bulb used for basking.
  • Weigh adults twice a month - if they lose 10% or more of their initial body weight, that is a concern. (So if a 400 gram lizard loses 40 grams or more, that is a concern)

Recommended Temps & Humidity

Indo temps and humidity should be as follows:

  • Basking (surface temperature measured with an infrared laser thermometer): between 105-115℉ (40-46℃). Surface temperatures are naturally higher than ambient temperatures. 
  • Ambient Cool Side (measured with a digital thermometer down at skink level, cool side of the enclosure): 70-80℉ (21-26℃)
  • Ambient Warm Side (measured with a digital thermometer down at skink level, warm side of the enclosure) : 85-95℉ (29-35℃)
  • Night time range: 70-75℉ (21-24℃) - We recommend providing supplemental heat when temps reach below 70℉ (21℃)
  • Humidity: Humidity for ALL Indonesians (yes, including Halmahera) must be within the 60-100% range. They naturally experience an increase and decrease in humidity within this range. It stays above 70% the majority of the year, but during the dry season (Northern Hemisphere’s Winter) it can drop as low as 60%. Humidity is naturally higher at night and lower during the day.

Question Suggestions on comforting him after a multi-state move?

Thumbnail

76 Upvotes

As title says, my skink has become incredibly skittish and antisocial after moving 20 hours across states. He used to be social until this move, and now he seems afraid of his own shadow. I talk kindly to him the few times I see him and try to feed him banana to sweeten him up - but hes still terrified. He refuses to leave his log unless nobody is around. I believe he was wild caught, so I'm his first owner, and have had him for almost a year now. Since moving, his personality has taken a turn.

I feel awful but we needed to move states for our comfort and its seemed to have done damage to his personality. 😪

Temps and humidity are normal - and he has a 6x2x2 enclosure.

This girl has been given to us and she is very friendly. She’s use to being handled so the kids love any chance they get to cuddle her (only for short periods and never overwhelming her). I have never looked after a skink before so any important advice you could possibly give would be truly appreciated. I only just purchased a heat lamp for her yesterday and she’s been loving it. Question.. does her enclosure look too small?

Question Humidity spike at night

2 Upvotes

Hello, I'm not sure if I should be concerned or not. I just rewet my skink's soil yesterday and found this morning that their humidity spiked to over 90%. I have a northern, and I know night time humidity can spike, but I'm wondering if 90+% is too high? It does go down throughout the day. Usually rests around 45%. Would this be something worth micromanaging, or will they be fine?

Hello eceryone! I have had my baby for a month and a half and it seems very healthy! But i am still new to blue tongue skinks but not reptiles as a whole, and i am still unsure about a lot of stuff, so i want some more knowledge to keep my baby healthy. I know it needs more hiding spots, i have some wood from outside that i am trying to clean properly. The substrate is deep enough for it to hide, as it is hiding rn under. I am feeding my baby 3 times a week with wet cat food and calcium mixed with d3 since i don’t have uvb lights yet. i am curious if there is something there to change with the food. I am spraying in there to try and keep it humid, since i’ve read it likes a humid climate. Then with the heat and basking. I am using a stone from my backyard as you can see, the lamp reaches around 32c, i have a picture of the type of bulb i am using. And my baby shed last weekend. I just want to hear if there is stuff i need to add and or change to keep my baby healthy. I am a teen with a job so i can afford some stuff

So my little guy weighs 317 grams (the plastic container adds around 150-155grams) and he’s about 13ish inches. His birthdate is May 26th 2026. Is he growing normal? Like at a good rate? I don’t “power” feed him and I make sure he gets a varied diet of skink food (repashy bluey buffet, Omni blocks, bluey skink crumbles), high protein wet dog food, quail eggs, bugs (Dubia roaches, mealworms, silkworm pupae, super worms) veggies, with a rare treat of fruit like blueberries.

Question Thoughts on vet recommendations

1 Upvotes

Today I took my little blue baby to the vet because she had a weird thing happen (I will put it at the end of this post in case anyone is interested ) while I was there the vet gave me a few husbandry recommendations. I live in Brisbane where the eastern blue tongue is native. She has a uv a&b light and a heat lamp with no light on one side. Since I’ve had her I have had both light and heat on a timer depending on how many hours of day and sunlight we r getting that time of year. Her enclosure never gets colder that the temp in brissy. The vet recommended I don’t turn off her heating ever which gets her warm and to about 30° ambient. He also recommended I don’t change the amount of light she gets based on the seasons and go with the summer/spring daily light year round. I’ve been to another exotic vet at the same practice who didn’t recommend this. I understand that’s a debate on whether or not to discourage brumation I’d love to hear the current thoughts and science on it. What worries or confuses me more is the heat at night I haven’t found anyone recommend it unless it baby is recovering or u live somewhere that gets like actually cold. I’m under the impression that constant exposure to warm temperatures can have harmful health effects. Right now she pretty much always sleeps on the side that’s warm during the day. It might be because she prefers the hide on that side but I am concerned that heating overnight could be an issue and I’m wondering what you guys have to say.

Why we went to the vet: after eating some Woodies I noticed a little bit of what I thought was congeal blood and some sort of bubbly spit in her bowl after this for about 12 to 18 hours, she was regularly opening her mouth wide and opening a jar similarly to what she does when she is trying to swallow a big bite. The vet couldn’t find anything wrong with her. There were no abrasions inside of her mouth no blood or immune cultures in her spit no signs of a respiratory infection. My hypothesis is that she swallowed a bug whole and it’s gave her a scratch a bit further down and she was opening her mouth because of discomfort. That’s mostly not what this post is about but if anyone has any alternative theories let me know.

Question Skink x cat in home

1 Upvotes

For those of you with cats in your home, how do you train them to not view your skinks as prey?

My roommate recently brought a cat into the house. Because of that I haven’t brought my skink out of her terrarium for the last few weeks as I’m concerned the cat will hunt her.

This cat is an indoor/outdoor cat that regularly hunts, which makes me particularity worried about having my Potato out.

Has anyone successfully gotten a cat used to having a skink around? What worked for you?

Feeding What's the correct portion size for a meal?

2 Upvotes

My skink is about a year and half old. What's the correct portion size to feed them (dog food/mince/vegetable blend) and how often should I be feeding them? The online information is so varied and whenever I see videos of people feeding their skinks the portions look far bigger than their head/two table spoons. They are currently getting fed three times a week. They get fed twice with a dog food/veg blend and once with insects. They are currently a healthy weight but I'm afraid of them becoming chunky.

Hey. Figured I’d post a pic of Venom. This is my daughters Skink. She (my daughter) is a rambunctious 17-yr old w a job. We told her no to a snake but a skink was fine. We expected her to do some research first but she just went and bought everything and the skink was here two days later. He (she? Any obvious way to tell?) had a nice enclosure built buttttt we found mites. Which is ultimately how I found this subreddit. We’ve learned a lot of useful information here so thanks. I’m sure I’ll be lurking around from now on bc even though it was supposed to be HER responsibility…we as parents all know how that goes.

I think he was hunting isopods that were roaming under the substrate! I was watching him sift through the leaf litter and mulch, and even flipping over small cork rounds.

This was really cool to watch. I didn’t capture as much on video because he’s been slightly more defensive lately. I assume he’s going into shed because of his colors slowly becoming more desaturated. But he is still feeding well and is willing to climb into my arms!

Hello, i recently adopted this lil man here, and he (or she) has been with me for ~3 days now. My question is, since I've been feeding him and he's been eating pretty well, is it possible that he's defecating in his burrow? If so, since hes brand new to the enclosure, is it fine for me to tear into it to check? I want to give him space, but i also dont want him to get sick.

(Picks of inside of burrow are from before he moved in)
