Novel aerial observations of a possible newborn white shark (Carcharodon carcharias) in Southern California

Abstract

AbstractThe white shark (Carcharodon carcharias) is the largest macropredatory fish in the world. Yet, there remains a paucity of data on the early life history and reproduction of this iconic shark. Here, we present aerial observations of an individual white shark that appears to be sloughing a white film from its body. We propose two possibilities for the possession of the white film: (1) this is a newly born white shark with intrauterine substances still adhered to its body, or (2) this white shark has an unknown skin disorder resulting in shedding, discharge, or possibly a microbial growth over the dermal layer. We discuss the possibility that this individual is a newborn and its implications for the Southern California region as a critical birthing location.
