A month and some change back I posted some of my photos from the "
Lizards & Snakes: ALIVE!" exhibition at the American Museum of Natural History and asked you all to to
do a little homework. Well, fellow blogger
Susan stepped up to the challenge and successfully named each one of the squamates I photographed. As promised, now it's time to briefly talk a little about each of them and their relationships with one another. I'll also be including a ton of Wikipedia links so that those who want to find out more about the species or clade I'm talking about can easily do so (I normally take Wikipedia with a grain of salt, but to be fair, they are starting to cite a lot of references so check those out too).
The first
squamate pictured was the
serpent Corallus caninus, commonly known as the emerald tree boa. This
boid is a arboreal native of the rain forests of South America, and as you can see, is a pretty good looking animal. This specimen in particular is seen in a typical
Corallus pose, coiled around the branch of a tree, head in center. It will remain like this for most of the daylight hours, as it is a nocturnal hunter. Staying coiled up as it hunts, it extends the head and neck out, waiting patiently for a small mammal, bird, or frog to pass by before it strikes with atypically large teeth for a non-venomous snake. It then pulls it's prey in, and like other boas, constricts it until it suffocates. And for those who already think snakes are creepy enough, here's a
fun fact for you:
Corallus is ovoviviparous, meaning that the mother never lays eggs, but rather, retains them inside of her body as the young develop and hatch, until she finally gives birth to live young (Mehrtens 1987). Awesome.
