Anyone who’s raised anoles has likely run across the occasional slug. I’m not talking about shell-less gastropod mollusks, but rather about the flaccid yellow eggs that anoles lay from time to time. Slugs are uncalcified and generally considered infertile. Because slugs never develop viable embryos and tend to quickly rot when incubated most lizard keepers simply discard them. Is there anything to be learned from slugs? In our colony, we tend to recover the most slugs early and late in the breeding season, but we’re not sure why this is the case. Is it possible that the male and female are a bit out of sync, or that the female is priming her reproductive tract for the real deal? We’re also recovering more slugs in our hybrid crosses than in pure crosses, but we’ll have more on that later. Are any reproductive physiologists out there more familiar with the mechanisms responsible for production of slugs?
