The 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.

白鲨（Carcharodon carcharias）是世界上最大的大型掠食性鱼类。然而，有关这种标志性鲨鱼的早期生活史和繁殖的数据仍然很少。在这里，我们展示了对一只大白鲨的空中观察，它似乎正在从身体上脱落一层白色薄膜。我们提出了拥有白色薄膜的两种可能性：（1）这是一条刚出生的大白鲨，其体内仍然附着有子宫内物质，或者（2）这条大白鲨患有未知的皮肤疾病，导致脱落、分泌物或可能是真皮层上有微生物生长。我们讨论此人是新生儿的可能性及其对南加州地区作为关键出生地的影响。
