“…Epidemiological studies suggest a relationship between environmental contaminant exposure and congenital anomalies in humans and wildlife, including urogenital defects (Lyons 2007, Winchester et al 2009). Several persistent organic pollutants were measured in the blubber of subsistence harvested belugas from Cook Inlet, and both polybrominated diphenyl ethers (PBDEs) and semi-quantitatively hexabromocyclododecanes (HBCDs, in particular, α-HBCD) significantly in creased from 1995 to 2005 for both sexes (Burek-Huntington et al 2022).…”

Congenital defects and herpesvirus infection in beluga whale Delphinapterus leucas calves from the Critically Endangered Cook Inlet population

et al. 2022

Cook Inlet beluga whales (CIBs) Delphinapterus leucas are Critically Endangered and genetically distinct from other beluga populations in Alaska. CIBs are exposed to numerous natural and anthropogenic sources of mortality and morbidity. This study describes congenital defects observed in 2 CIB calves. The first case, an aborted fetus, was characterized by lack of a peduncle and flukes, anorectal and genitourinary dysgenesis, and probable biliary dysplasia. The second case, a male calf, had a perineal groove defect and suspected secondary peritonitis; it also had a systemic herpesvirus infection. Further studies are needed to determine if such defects are due to genetic mutation, infectious diseases, nutritional imbalances, or contaminant exposure.
