Just an update - we still have 23 tadpoles thriving and now there are 3 with legs. Their names are:
Polly ("She's got legs, she knows how to use 'em."
Lieutenant Dan ("Lieutenant Dan, you've got legs!")
Bo ("Mr. Bojangles, dance...")
I am not going to name them all - maybe a contest is in order to come up with some good names - but once they all start looking the same (as if they didn't right now!), it's going to be hard to tell Polly for Dan or Bo or whatever! ha ha
More photos to come when they are more evolved. Right now they just look like tadpoles with tiny little legs on some of them. They are voracious, though, eating and sleeping a lot.
