Adult male basilisks have tremendous crests and sails with which to impress female basilisks, and humans (I know I was impressed, anyway). These lizards are extremely agile and speedy, but they're not averse to posing for a photo.

The pair in the second photo are probably adult females, but could be younger males. Basilisks are usually found near water, and these were no exception, basking on the rocks near a stream.

The little tyke in the top photo was perhaps the smallest of the numerous basilisks we saw on this trip, about six inches long or so including its tail.

The bottom photo shows another adult male on a log in the forest, backlit by the late afternoon sun. The full-sized ones like this are perhaps 3 feet long including the tail.

We caught this large female basilisk sleeping at night on a large leaf. When we took her photo by day, she sat still for about two shots and then bolted into the forest.

Here is a complete list of the species we found on this GreenTracks trip.
