We are 132 days past oviposition and the remaining six eggs appear to be hanging in there. One of the eggs has dented in, which I am hoping means that it will hatch in the next few weeks and does not mean the embryo has died. The other eggs remain rigid and appear to be well, fingers crossed they come to term! The Grumbach has … Continue reading Day 132: So close, but so far!
Mark Seward says 124 – 150 days. I am at Day 102 and it’s hard to be patient. Six eggs remain in the incubator and I have not touched them in some time for fear of creating a problem that didn’t exist. The Grumbach has done an admirable job of keeping both temperature and humidity very stable, and the S.I.M. Containers are keeping the eggs … Continue reading Day 102: How long do Gila monster eggs incubate?
This very exciting event recently popped up in my news feed! A symposium specifically about Heloderma in the New Mexican desert? Count me in. The website is currently up and you can follow the updates here: https://www.biologyofheloderma.com/home. Hope to see you there! Continue reading Biology of Heloderma Symposium
Not much has happened since the last update; one good egg died leaving me eight healthy growing eggs in the Grumbach incubator. A universal agreement on Gila monster eggs is to leave them the F* alone during the long incubation time. I have a hard time doing this but have been a good bean and done so by only check through the incubator’s clear door … Continue reading Update 5: Waiting is the hardest part
It’s been all quite on the update front as, well, there has not been much to report. Until now, that is! On Friday June 7, Gila 03 dropped one egg over the night and I came upon it at 6am when getting up for work. I candled the egg but did not see a blood ring (something that viable eggs have) but put the egg … Continue reading Update 4: Eggstravaganza!!
So, I made a third update some weeks ago but found out I never posted it, so here it goes… UPDATE 3 – May 3, 2019 The females had been separated from the males for about two weeks now as I observed both females being copulated with and, according to other successful breeders, mating is wrapped in in a two week period. Though both weight … Continue reading Update 3: Sitting, watching, waiting.
I discovered Grumbach incubators from the book Beaded Lizards & Gila Monsters Captive Care & Husbandry which states that “Grumbach incubators are especially well suited for hatching Heloderma eggs”. After some Google searching and browsing through reptile forums I quickly found that the problem with Grumbach, a German manufacturer, is that these machines are not commonly used in the US (especially for reptile egg incubation) … Continue reading The Grumbach S84 Incubator for Reptile Egg Incubation
Gila monster 06, formerly known as Joy, was thought to be a female and was the one that was sick. Now that Joy is better, I wanted to finally determine confirm her sex (though based on head size I guessed female). My intention was not to breed, only to watch the reaction and once I put Joy in the cage with a known male (one … Continue reading Just when you think you know someone…
My first encounter with this behavior was many years ago when my best friend saw the Gila monster in its cage upside down and unmoving. He called in a panic and said that my pink lizard (his reference of Gila monsters to this day) was dead. Of course when the cage was opened the lizard sprang to life and was quite aggressive upon examination. Now … Continue reading Why do Gila monsters play dead?
When I purchased the six Gila monsters, No. 6 (now known as Joy) was the only one that looked a little off; she was skinnier than the rest and her fat reserves in her tail were depleted. I thought it may have been from overwintering but that was not to be the case as it quickly became apparent she was sick. She excreted a red … Continue reading Joy’s pain: a Gila monster’s road to recovery
