Although they are tiny, usually 2 1/2-3" total length and 1-2 grams they are pretty tough little guys. You have to be quite careful as, just like the adults, they will surprize you by taking a leap from your finger to the ground and land totally unscathed. Now mind you, I do all in my power to prevent this but sometimes they are really daring!
And talk about moxie, they puff out that delap and open their mouth as wide as they can and they look like a mouth with leggs! I guess the idea is that they will make up for size with posture!! LOL!!
If I run across the picture of the one that bit my hubby's finger I'll post it for you.
