I don't know how they taste, but they are pretty good fish bait, once you get them out of their shells. Well, I don't use 'em for that, but I have seen it done.
My kids used to like catching them for pets too, when they were younger.
One night, in college, my brothers and I went frog gigging in a canoe. We only had one gig, so also took along a baseball bat and a net, both worked good on the bull frogs, we got a lot of them. The frogs taken with the bat didn't look as pretty as the gigged ones, but the legs still tasted as good, once we got them fried.
hadtuh clean muh monitor after that one...
I can't imagine sticking a hermit crab on a hook. It just ain't right. :-/
And frog legs ain't bad at all! I usually drive down Tamiami and stop at The Pit BBQ to get gator tail and frog legs when the mood strikes. Yum, yum!
Shoulda taken Flat Frodo there when I took him to Shark Valley that day.
