Checked on some eggs and saw a couple heads poking out!

Congrats! Well done, Ben. Let us know the count when you know on the babies (i.e. Albino Tigers and Albinos)!

Thanks Pat! Will do! I have a few moldy eggs that I just don't know about, so we'll see!

The "Man" does not have enough??

Just what you guys need 100,001 retics in your wealth of space!!!

More retics per square inch than ANYWHERE ON THE PLANET is the PREHISTORIC PETS unsaid MOTTO!!!!!

Nah...Just kidding...we could also say more Redtail Cats per square inch than the AMAZON!!!

Ben,

Those are awesome, can you please tell me the amount of days from laying till pipping began ?

Thanks a lot! It was 86 days from laying until pipping. So pretty standard time period.

Thanks!
Ben

That is pretty standard, good work, longest I ever got was 103/104 days at 87 degress.

but temps did fluctuate between 86-92.

I had my inc set at around 89-90 for the most part, since I'm using a pretty big incubator, I'm sure the temps could have gotten to 91 at times whenever it kicked on to warm up, but that's not really a biggy.

thanks again for the intel n/p

Not a problem! I'll keep some pics updated of the rest of the clutch coming out and the dates they do!

Anyone have any information on the maternal incubation temps of retics. There is a fair amount of info on the intra-coil temps of burmese during maternal incubation, and I have a fair amount myself. But I have never seen any detailed data with regards to retics.

Kelly

Average intra coil temp was 90 degrees. She even raised the temps to 90 while going against 77 degree ambient temps. Below 70 she maintained temps at 87 degrees. ( heater malfunction )

In that breeding 69 hatched out of 96 laid eggs. That is not a typo 96 fertile eggs. Others where fully formed and had pattern (light).

The female belonged to Charles Juiliano, the male was mine. Both imported in early 80's and did not breed till they where at least 14 ears old.

Female recently perished, last two years of her life she barely fed and obvious signs of deterioration were occurring, her last and final clutch was 3 years before she died of old age.

She was definitely over 24 feet. When I bred yellow heads the female laid about 35 large eggs, the Malaysian females eggs where half the size of this yellow heads. But babies grew to an average of 18-20 feet.

The female yellow head temps where slightly lower at average of 88, against ambient temp of 85 degrees.

Malaysian silverhead subsequent clutches where 65 fertile on average.

temps may not be exact due to probe thermometer -+ 2 differential.

how were these cages being heated?

Kelly

in almost all instances the entire room was being heated and also 3 incandescent lights inside enclosure. ( primitive is a good word in my opinion ) Home made enclosures 4' X 4' X 8'.

First occurred in an apartment with many unexpected surprises. If it could go wrong it did. Still pretty good hatch rate, I was chewing my nails for over 100 days. I immediately noticed reticulated pythons do not shiver like Burmese pythons, I did notice rhythmic breathing on the part of female.

Note I have not bred any pythons since 2001. I have worked with various colubrids, but nothing since 2004. With my collection in excess of 55 specimens, I should have some things going on in the future.

Glad to be coming back to the herpetoculture circles.

I will be working with a few species next season hopefully. bad divorce long story.

Frank, I knew retics had some thermoregulatory capabilities, but wasn't aware that they were to the degree that they could overcome ambient temperature differentials of that magnitude. I knew that molurus sp. had the capability of countering gradients that large, but had not seen this information for retics until now. With regard to retics, I would suspect that the northern populations in their range would have more refined thermoregulatory capabilities than those of the equatorial populations. Interesting stuff. Thanks again,

Kelly

I was shocked when she raised her temps like that. Prior to that I thought they could only do like up to 5 degrees. If I didn't see it myself I would be skeptical. I assure you, I am not making this up.

She was the only retic I have seen that actually lays very large clutches, like the ones you hear about in the older literature. The interesting part to me was the major differences in the actual size of the eggs she laid, especially when compared to a 16 foot yellow headed retic that laid on average 30 large eggs. Charles and myself where selling them in Hamburg Pennsylvania in 1995. Tiger's where around but not yet available to the public.

They where the only captive bred retic's at that show. Female was docile and male was agro, most babies demeanor mimicked the mother leading me to believe aggression is most likely a hereditary trait. Now we know it is.

I sold them for 65 dollars in 1995, since they outwardly did not appear to be aggressive they sold pretty quick. Leftovers we sold to the "Kick Brothers" at wholesale prices.
Lots of fun and also very interesting. If you have access to pythons and boa and a temp gun. After snake consumes a good size meal. Take the snakes temperature at lump and other parts of their body and you will notice that a product of the digestive process appears to be heat created that raises the core body temp up to 5 degrees above ambient temperature. Interesting stuff for a poikilothermic animal. Much more too learn indeed!

I do not own a camera, but I do have a "old" picture of a retic from my 2001 clutch. ( Charles Juiliano at that time was my partner in crime, my new partner is my best long life friend john Rodriguez. )

I still have this snake and she is 12' long now.

definitely was a "keeper"

I know I have posted this picture several times, but it is the only one I have of her. Color intensified as she grew.

Kelly,

I would be extremely interested in you taking body temps of your green anacondas after a good sized meal. Up to and including ambient and air temperatures. I am just curious. If digestive process produces elevated body temps in comparison to ambient and air temperatures of their enclosure.

noticed this as well, in boas, not just pythons.

I didn't get any elevation of temps with the colubrids, but they eat very small meals that are quickly digested in comparison to my pythons and boas.

Interesting Stuff!!!
