Hi Mark! I have a question about dendrobates tinctorius and I have yet to find the answer on my own. My university has several dyeing dart frogs on display, and I've noticed that especially when they are poised to hop, sometimes they will rapidly wiggle their middle toe on their back legs for a few moments. None of my professors seemed to know what that behavior might be linked to. Do you have any ideas?
I HAVE NOTICED THIS TOO. Actually I noticed it in some rather large toads of a species I cannot now recall. But they were constantly wiggling their toes. Then I started paying attention, and lo and behold, there are tooonnes of frogs that do it. I have no explanation for this, but I am glad I am not the only one noticing it! I thought maybe it is subtle signalling… but it could also be just a weird neural misfire. But it would be strange for one to be so consistent across the batrachia. So I have no idea.
