The Carolina hammerhead, a new species of shark, debuts
Date:11/7/2013

d at shark pups.

South Carolina is a well-known pupping ground for several species of sharks, including the hammerhead. The female hammerhead will birth her young at the ocean-side fringes of the estuary; the pups remain there for a year or so, growing, before moving out to the ocean to complete their life cycle.

In the process of looking at hammerheads, Quattro, his student William Driggers III and their colleagues quickly uncovered an anomaly. The scalloped hammerheads (Sphyrna lewini) that they were collecting had two different genetic signatures, in both the mitochondrial and nuclear genomes. Searching the literature, they found that Carter Gilbert, the renowned curator of the Florida Museum of Natural History from 1961 to 1998, had described an anomalous scalloped hammerhead in 1967 that had 10 fewer vertebrae than S. lewini. It had been caught near Charleston and, because the sample was in the National Museum of Natural History, the team was able to examine it morphologically and suggest that it constituted a cryptic species that is, one that is physically nearly indistinguishable from the more common species.

After publishing the preliminary genetic evidence for the new, cryptic species in the journal Marine Biology in 2006, Quattro and colleagues followed up by making thorough measurements (of 54 cryptic individuals and 24 S. lewini) to fully describe in Zootaxa the new species, S. gilberti, named in Gilbert's honor. The difference in vertebrae, 10 fewer in the cryptic species, is the defining morphological difference.

Apart from the satisfaction of discovery, Quattro has established locations and genetic signatures for a number of closely related, yet distinct, species in South Carolina's rivers, estuaries and coastal waters. The results will go a long way in furthering efforts to accurately define taxonomy and evolutionary history for aquatic life.
