First report of an embryonic dusky shark (Carcharhinus obscurus) with cyclopia and other abnormalities

Abstract

We report the first record of an elasmobranch (shark) with cyclopia and other abnormalities (albinism, absence of nostrils, a bump on the snout and a slight abnormality in the vertebral column). These malformations were found in an embryonic dusky shark Carcharhinus obscurus caught near Cerralvo Island in the Gulf of California, Mexico. Tomographic images were taken to observe these deformities in detail. The causes of these deformities are uncertain but may be attributed to congenital malformation during embryonic development (holoprosencephaly).
