I live in Houston where it can be both very wet and very hot. In our neighborhood the water tends to gather on the side of the road, from storm water and sprinkler systems, but most evaporates with the hot sun over the days ahead. There are some puddles that stay for a longer time (2-3 weeks) as the drainage in those areas is not too good and the puddles are a lot deeper. A bunch of frogs had a croaking night a few weeks ago and 3 puddles were full of tadpoles the next day or two. To cut a long story short, the rain has been pitiful and these puddles have almost dried up. Yesterday I was concerned about one of the puddles that had 1000 or so tadpoles running around, so I rescued about half of them into a cool bag and transported them to another puddle closer to home. However on visiting the first puddle today all the remaining tadpoles are dead. Any idea why? Do they miss their friends who were moved out?
