Abstract

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.

摘要

在野外通过视觉识别为当年幼体（YOY）的扇形锤头鲨（Sphyrna lewini）的两条鲨鱼，基于核编码单核苷酸多态性（SNP）和线粒体DNA序列被鉴定为大锤头鲨（Sphyrna mokarran）。这些个体分别于2013年和2014年在南卡罗来纳州的公牛湾和佛罗里达州的圣约瑟夫湾被捕获并放生。这些发现表明，大锤头鲨可能在这些区域内或周边繁殖，并突出了新的区域，这些区域可能成为未来大锤头鲨早期生活史研究的有效重点。
