Developmental endpoints assessed for abnormal development compared to normal embryonic zebrafish of the same age. The embryonic zebrafish metric (EZM) is based on a 24 point scale and is obtained by summing the EZM scores for every endpoint observed in an individual fish. The sum of all sublethal endpoints is less than the score associated with mortality.
