I'm reviewing my reptile presentation before I train some new folks to do it (I'm an Environmental Education Specialist so I get to do this ALL DAY :) ) and ran across something I can't remember from college biology.
In snakes that give live birth, specifically plains garter snakes, terrestrial garter snakes, and western rattlesnake--prairie subspecies, I need to get myself (and the new folks) clear on the internal progression. I know that the young develop in eggs internally, hatch, & are born live. What I can't remember is if they form actual eggs or just egg sacs. Can anyone explain this process or have a good reference?
I haven't gotten a question on this yet, but with kids it's only a matter of time :)
