A good-sized Costa Rican Coralsnake we saw in the grass on a family vacation. These are very different than the coralsnakes we have back in Arizona. It’s much larger and willing to strike, which it did repeatedly. These snakes are a handful to get photos of, but we managed and let it disappear back into the forest.
Brown-throated Three Toed Sloth from Costa Rica back in November. I’ve rarely seen them be more than brown blob up in binocular range, so some activity (slowly of course) was nice.
Crossing a metal bridge on a trail through the Costa Rican rainforest, we were stopped by the sight of a Blunt-headed Tree Snake in the latter stages of eating a small lizard. The lizard was still trying to escape, but the snake was not going to lose this one. These tree snakes, with their huge eyes and comically thin bodies, seem kind of goofy, so it was cool to see one doing what they do, and know that for as silly as they seem to be, to a sleeping anole it is a pretty terrifying animal.
A small viper from the relatively dry tropical forests of Pacific coastal Costa Rica. This Slender Hognosed Pit Viper was found crossing a path late at night. They are common in the area, and in good conditions, dozens can be seen in a single night.
The first of a handful (not literally) of Central American Eyelash Vipers I found on a family vacation a couple of weeks ago to Costa Rica. This blue-greena nd pink individual stayed the entire week on the same tree, moving lower at night to hope for prey. On the last day, a massive rainstorm got everything moving, and this snake took its queue to leave its tree and disappear into the tangle of green.
