Heloderma suspectum (Gila monster) First record of mating on the wild!

This was a cool find from May 2025 Herpetological Review I picked up while doing my daily scour for new Gila info. Gilas are so secretive it’s a wonder we can get them to breed in captivity with all the activity and interaction they have with their keepers! There’s also a related video which may be NSFW (but in a scientific way) which I will link below. I think my life would feel pretty fulfilled if I got to trail Gilas in the wild for research.

Just released! Fatality Following Gila Monster Envenomation official report!!

There aren’t many anecdotes of Gila monster bites the century, and especially not fatalities. When this envenomation occurred, there was a lot of speculation and talk about the victim’s health and speculative reasons why he died and so many others haven’t. Now the official report has been released and laid to bed any speculation. Check it out and take care of my friends; never underestimate the bite of a venomous reptile!

And so it begins! Welcome 2026 Gila monster breeding season!

It’s that time of year of year, time to wake up the monsters and kick off the 2026 Gila monster breeding season! The cages have been cleaned and are ready to go, welcoming back home the inhabitants that have been in quiet winter slumber since December. The rise in temperature takes place over several weeks and continues into March as the Gilas go from complete cold and darkness to daily life of regular light and temperature changes.

Wakey wakey, mice and eggy’s (or something like that..)

Last year was our best year not only in success of eggs hatched, but also producing some very uniquely patterned babies. Our hyper pink line produced one baby which is already showing its insanely pink coloration, the aberrant line is producing some amazingly interesting patterns.

So pink at only five months old! Photo by ST who is shaming me with these photos for selling this Gila:)

As with every season, hopes and dreams abound thinking of the pairings and who will produce what. Regardless it’s a win, just working with Gilas and producing babies is enough for me. I’ve already started reviewing my notes from previous years and re-reading my mentor Dr. Mark Seward’s “Gila Monster Propagation” and other books and articles to see if I can glean anything new (which I always do).

Our 2024 holdback is getting more orange everyday!

One thing is for certain, it will be another amazing season so stay tuned for updates max we embark on a new adventure in Gila monster! The 2026 waitlist is getting pretty beefy, if you want to reserve a Gila do so now! This is especially true if you are looking for a hyper pink or “Gators” orange, or the very limited aberrant line!

Our Gilas bleed blue and orange FYI:) Go Gators!

The 2025 Gila monster breeding season comes to an end.

The end of our 2025 Gila monster breeding season came to an end this week when Gila 62 fully emerged from the egg! Ten eggs made it all the way and I could not be happier with the results! Two new moms (Misty and Lucy) produced their first viable hatchlings and stalwarts Belle and Heather did not disappoint. Above are the babies born this year and it is interesting to see what the pairings have produced over the years.

Can you see the hyper-pink one?

As with every season there were wins, losses, and lessons learned. I feel lucky and proud to have been successful another year breeding Gila monsters. We have a just a few babies are still available as of this post so drop us a line if you see something you like! And our 2026 waitlist has already started so jump on now especially if you are looking for a hyper-pink or aberrant (or both traits together as we had this year!). A few photos from the season for your viewing pleasure below!

25.10.19 Can’t hardly wait!

Someone needs a nail trim!

The anticipation is killing me. So close to hatch time for our 2025 Gila monster babies it’s hard not to check multiple times a day! with this years pairings it will be a very interesting year to see what pops out! Hopefully some high pink reduced pattern Gilas pop out, but no matter what they’ll be beautiful baby Gilas to enjoy! Stay tuned!

Our 2024 holdback is getting more beautiful with age!

2025.08.24 update: Gila monster eggs incubating and the preparations for next season

Gila monster breeding is not a black and white endeavor.

As with every Gila monster captive breeding season, there are wins and loses, new things learned and insights gleaned to improve next year.

Is that a xenomorph in deep space laying its deadly eggs? No it’s just our banded Gila monster Lucy resting between laying much less dangerous eggs. No facehuggers here thankfully.

First the wins; I had an improved nesting experience (thanks to my mentor Dr. Mark Seward) with my stalwart females Belle and Heather who had their best year yet. The newbie females are still figuring it out and they laid partial clutches which are good, but held eggs that were ultimately unviable. Also, we had a disproportionate ratio of males to females so had to do some calculated male swapping so that likely factored into things. The females are also recovering nicely post breeding which bodes well for next year. I currently have ten good eggs in the trusty Grumbach S84 incubator which is great. There was a total of 22 eggs, 10 of which were infertile slugs or laid late, 2 fertile eggs went bad about a month after being laid, and 10 still a-cookin’. I always feel that if I have one egg hatch in a season it’s a win!

The losses are always rough, especially when you lose a Gila and this year we lost a female that became egg bound. It is tough and in retrospect I should have intervened sooner, but assumed that since she was eating and defecating the eggs would have eventually passed on their own. Sadly, this was not the case. It seems the time between oviposition and expiration is much shorter than anticipated and generally experienced with other reptiles. Now I know not to wait and to intervene sooner, but I am deeply saddened that this information came at the cost of a beautiful Gila monster.

Winnie, full of eggs and hope..

Another battle that is ongoing is with our axanthic Gila monster Winnie that has refused to eat after laying five infertile eggs. She has been to the vet and is on antibiotics, but she is still not eating voluntarily. Not a good sign but she is eating eggs with a little help from me and I am hoping she recovers. As it’s late in the season and she should be bulking up not fighting for her life, Winnie will be taking the next year to recover as long as she pulls through. She was sick when she arrived in 2021 and after treatment then she has had been doing well until now. There’s obviously an underlying issue that we will get to the bottom of over the next year to ensure she gets healthy and stays healthy for the rest of her days. Stayed tuned for updates on this front…

Last year’s holdback continues to blow me away as she grows with a deepening orange and dark black coloration.

So, it’s been another year of learning, living and loving our precious Gila monsters. Keeping detailed notes is helping to make changes in the future which will lead to greater success and hopefully no more losses. I can’t wait to see what pips out of the egg this year, it truly makes all the struggles and planning worth it when the babies come out!

PS – My 10-year-old daughter is creating videos for Goatsby’s Place, so they’ll be some fun shorts on YouTube coming up soon!

Winnie in the sun.

2025 Gila monster Season update: Eggs a-comin’ and the long wait ahead

Pairs are separated after ovulation.

The pairs have been paired and soon we get to see how things went. I’ve been doing this long enough not to expect miracles, but I must admit to being a little more than excited about having six females, including our axanthic, potentially laying eggs this year. It is always a bit like Christmas morning when you’re a kid waiting for Gila monster eggs, you’re not quite sure what you’re going to get, but you hope it will be everything you’ve dreamed of all year. All the planning, cooling, feeding, and pairing comes to fruition or failure now.

The Gilas get very close throughout the season.

Setting up the pairs in hopes of achieving specific traits such as high pink or orange, reduced or abnormal patterns, or axanthic, is meticulously planned based on babies that have been produced here. I am in touch with many of the folks that have purchased Gilas from us here at Goatsby’s Place and track how they grow to try and replicate these traits. The axanthic line, originally from Seward’s project, is very exciting and we hope to have some 100% hets this year from that pairing.

Smile you’re on Candid Camera! Pairs are watched and recorded throughout the day and night for mating activity.

After oviposition the long wait begins. It’s been common for eggs that will not make it to term to expire within the first 30 days after being laid, though they can go bad at any time really. Never count your Gilas before they hatch is a good analogy! There’s a lot of hurry up wait at this point but it’s all part of the process in breeding Gila monsters.

Every year starts out with hope and we are thankful that it has ended with baby Gila monsters for the past six years. Some eggs are not fertile or make it to full term, but as long a a baby Gila pips its head out of the egg in the fall it is all worth it!

2024 babies: which pattern do you prefer?

After a long winter slumber..

Loading screen from The Bard’s Tale (one of the first computer RPG’s from 1985)

The Gila monsters at Goatsby’s Place are waking up after the long winter’s nap, officially kicking off the 2025 Gila monster breeding season!

One of our newer additions is waking up after being brumated since December. It takes them a week or so to really get moving again.

Every year starts off with a lot of hope, but this year is even more hopeful as we have a lot of exciting things going on this season. We have a pair of beautiful banded Gilas that are new to the mix, and two females that bred for the first time last year (one is Winnie the Seward axanthic Gila, the other is the stunning pink banded Gila Lucy), and our stalwart females Heather and Belle will be in the mix again this year as well. As the Gilas wakey wakey I will start ultrasounds this weekend and feeding begins next week. First will be small meals of single adult mice, and once they defecate regular feedings will begin.

Lucy was not bred last year to build her weight and strength to successfully breed this year.

Stay tuned for more updates and photos, and if you wish to get on our list for 2025 please do so earlier than later. We have a healthy list already (many are repeat customers which is amazing!) and as a smaller-scale breeder, babies will be limited!

Our holdback 2025 banded Gila!

Last one out’s a rotten egg!

The last of our 2024 Gila monster egg is hatching as I write this. Looks to be another stunning banded Gila! The baby Gilas take a few days to come out of the egg, and it seems to take every ounce of newborn energy to do so. It’s also amazing to see as the size of the baby defies the space in the egg. All the trials and tribulations throughout the year just melt away when that little Gila pokes its nose through the egg.

All that in there? How?!
I think we all wish we can get back in the egg sometimes..

Our 2024 Gilas are sold out, and 2025 is filling up fast. If you are interested in getting one of our Gilas please reach out now to get on the waiting list.
