Two sharks, visually identified in the field as young‐of‐the‐year ( YOY ) scalloped hammerhead Sphyrna lewini , were identified as great hammerhead Sphyrna mokarran based on nuclear‐encoded single nucleotide polymorphisms ( SNP ) and sequences of mtDNA . Individuals were captured and released in Bulls Bay, SC , and Saint Joseph Bay, FL , in 2013 and 2014, respectively. These findings indicate S. mokarran may be pupping in or around these areas and highlight new regions that may be a productive focus for future research on early life history of S. mokarran .
