She actually shed for second time after pos 2 days before I predicted she would give birth.......so much for predictons lol

with our greens. They are not very consistent when it comes to POS timing or occurrences. I have had female greens shed anywhere from 1 to 3 times between ovulation and birth. They also do not show a consistent pattern as to number of days the sheds occur before birth of the young. Another inconsistency is the number of days the newborn young go before their first shed. Jud and I have seen them go anywhere from 5 days to 3 months. Anacondas are definitely the enigma of the boid group.

That female yellow looks good, please keep us updated on her progress. Thanks,

.........Same goes for newborn yellows with the sheds, first sheds last year started at 10 days(5 on day 10), then a trickle of sheds, the last 2 ate at 4 months after 2, going on 3 sheds.

I have studied many different boid's reproductive biology and noticed quite a few do not seem to follow the POS like BCI and BCC. many shedding several times from ovulation to parturition and or egg deposition. Same for pre egg laying sheds as well. Brazilian rainbow boas do not appear to follow the POS as in # of days from etc... more people on that forum are going to keep more accurate data to see if the POS is meaningful as in BCI and BCC. Most likely greens and yellows do not follow their pattern's, which to me makes sense due to the major differences in the genera. good stuff!!! I am quite interested in your temperature data in regards to your Sri Lanka pythons. Most likely differs significantly from Python m. bivittatus. So I would imagine the reproductive biology of not so closely related snakes could be quite variable and species specific in nature.

I have noticed over the years that the boa group tends to show these inconsistencies to a greater degree than the pythons. The larger python species, especially the molurus group, are very consistent in their reproductive patterns. Molurus respond beautifully to changes in environmental temperature and photoperiod to cue their reproductive cycle. They are very consistent in that they pre-lay shed approximately 3 weeks after ovulation. Usually deposit eggs 27 days, plus or minus 2 days, after pre-shed, and also deposit eggs 49 days, plus or minus one day, after ovulation.

So far the female Sri Lanka is maintaining the egg mass at 91.5 F. This is about 1 degree cooler than a burmese female would hold the egg mass temp. I am still very interested to see if the eggs hatch at day 56 like 95% of all maternally incubated burmese eggs.

this data as well. Thanks Kelly
