Mud Puddles

Tadpoles Vulnerable To Drought

Congratulations (again!) to Kathie Fiveash, the first Naturally Curious reader to correctly identify the rough patch in Monday’s Mystery Photo as tadpoles that were stranded in a puddle that was drying up.

Most tadpoles acquire oxygen in a number of ways — through gills, through their skin, and by breathing air into their lungs. In this case, a lack of access to oxygen in the water has left them high and dry, as their lungs are not developed enough to provide them with the necessary amount of oxygen from the air. A sad ending for these young frogs, but a goldmine for scavenging raccoons, skunks, foxes and birds.
