Yellowfins or Greenheads?

Mark Scott of SC DNR just posted this to YouTube and I wanted to give it a shout-out.

Very nice underwater footage of the Middle Saluda River, in the Santee Basin of South Carolina. Whenever you drive over a bridge and look down at the brown waters of southern rivers, don’t think for a minute there isn’t a really interesting aquatic world beneath the surface!

The shiners are labeled green head shiners in this video, Notropis chlorocephalus. Until very recently they were considered part of the yellowfins that I have worked on (N. lutipinnis), but Mollie Cashner has been doing phenotypic and genetic work to show that there is more going on in terms of the history of these fish and these drainages.
