Toe vibrating in Poison Dart Frogs?

[Jordan B]

Hi,
I understand this is a typical behavior in the frogs, but can someone explain its purpose and tell me some more about it? Also, is there a scientific term for the tapping/twitching/vibrating that the toe's do? Thanks,

I think it may be a terratorial, or mating display. Not too sure, would make sense tho.

No..... a reasonable guess.... but incorrect. But hey, good try.

Based on what I have read, the toe tapping is actually used to assist in finding food. That is... the vibrations from the tapping may sound like rain to termites within a termite mound, or in a piece of wood. These vibrations stimulate them to leave their nests. The frog can then pick them off as they come out of the opening. A neat little trick.
It is probable that there are other reasons for this behaviour, though this is the only one that I am aware of.

I thought about that, but then second geussed myselk b/c these guys are so small. BUT dont judge a book by it's cover. Thanx for the info

Thanks Double J (and snakehunter). That is really interesting. Do you think that it could possibly be used for communication and/or breeding as well?

With respect to breeding.... it's all about the calls. The toe tapping does not play into breeding, just feeding. When the males start calling, that is the dendrobatid equivalent of a deep manly voice like Barry White's.
