Hemochromatosis in bottlenose dolphins: clinical significance, risk factors, and treatment suggest non-hereditary etiology

Botttlenose dolphins (Tursiops truncatus) can have hemochromatosis (iron overload), evidenced by excessive iron deposition in the liver, transferrin saturation >80%, and rising high serum iron levels (>300 ug/dl) responsive to phlebotomy (Johnson et al., 2009).
