Vertebrate animals usually display robust growth trajectories during juvenile stages, and reversible suspension of this growth momentum by a single genetic determinant has not been reported. Now, Chen-Hui Chen and colleagues use a forward genetic screen to identify a temperature-sensitive mutation, called pan, able to suspend development in zebrafish.
