Yesterday morning, as I got my bike out to ride to work, I came upon this snake lounging on the stone steps coming down from our back yard. I didn’t have time to leisurely shoot this reptile because, well, I had to get to work, so the pictures aren’t amazing. But at least I documented another vertebrate. I think that’s two!

This is called viviparity and when I was in grad school I found that there’s actually a whole lot of squamate reptiles (snakes and lizards) that do this. I think a lot of people assume that mammals are the only ones who give live birth but sharks and reptiles also employ this strategy. It’s evolved a good number of times over the last few hundred million years.
