Boana lanciformis — Rocket Treefrog
Some other names for this species:
Sharp-nosed Treefrog, Basin Treefrog, Quacking River Frog
This species was until 2017 placed in the genus Hypsiboas.
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...
