A team of researchers working in China has proven that the three-keeled pond turtle embryo is capable of moving itself towards or away from a heat source in order to warm itself or cool down. In their paper published in the journal Biology Letters, the team describes how they subjected turtle embryos to various heat scenarios while monitoring their movements inside their shells to show that the turtles were directing their own actions while still inside their eggs.

Spadefoot toads are burrowing frogs that have large spade-like feet they use to dig tunnels under the sand, where they spend more of their lives in a dormant state that is similar to hibernation. But as soon as a rainstorm approaches, they spring into action the sound of thunder and the vibration of the raindrops hitting the ground are believed to be the cue that stirs the spadefoots into action.

Al visitarlo ahora, a principios de junio, estaba totalmente vacío pero bajo el barro seco se mantenía algo de humedad y allí se escondían centenares de pequeños metamórficos de sapo corredor (Bufo calamita).
