African killifish becomes fastest maturing vertebrate on record

(Cell Press) For most of the year, annual killifish persist as diapausing embryos buried in sediments across the African savannah. When rainwater fills small depressions across the landscape, the fish must hatch, grow, mature, and produce the next generation before the pool dries up. Researchers reporting on Aug. 6 in Current Biology have found that these small fish condense their life cycle even more in the wild than expected based on studies in the lab.
