I usually saw these large, gawky, angular frogs just before they leaped away. Their long pointy snouts make them easy to identify.
Here is a complete list of the herps I saw in the wild on my 2013 MT Amazon Expeditions trip.

Here's another one in the last few seconds before it was suddenly five feet deep in the jungle.

Last year I saw at least half a dozen of these frogs, but this year I thought I hadn't seen any. I had assumed this was one of the more common large Osteocephalus treefrogs at the time I took the photo, but hey, there's that long pointy snout!

This is the thickest Boana lanciformis I've ever seen, by quite a bit. It's so plump that I thought it must be some other species at first, but every aspect of it matches a typical B. lanciformis except the girth. Maybe it's a female almost bursting with eggs?

Something about the proportions of these frogs makes me think of people wearing frog costumes. Hmm, maybe next Halloween...

I'm pretty sure this is a very young Boana lanciformis, not yet grown into its human-in-a-frog-costume shape.

Another year, some more *Boana lanciformis* in ambush position.

I love the sight of a large frog clinging sideways to a stalk or trunk, ready for the big leap. Another of the numerous attractions of the tropics.
