April Flowers for redOrbit.com - Your Universe Online Among biologists, discovering a new species is akin to hitting a grand slam. Joe Quattro, a University of South Carolina ichthyologist, led a team that recently cleared the bases.

Confusion of identity between two shark species may threaten the survival of both. A new and unnamed shark species originally discovered off the Eastern United States seaboard discovered by Nova Southeastern University Oceanographic Center (NSU-OC) has a cousin that shares a striking resemblance: The endangered scalloped hammerhead shark. In an article published in the April 2012 issue of the scientific journal Marine Biology, scientists have revealed the new look-alike species to be found...

The International Commission for the Conservation of Atlantic Tunas (ICCAT) said that scalloped, smooth and great hammerheads, along with oceanic white tip, cannot be targeted or kept if caught accidentally. Three other types of hammerhead sharks are also included in the ban, including smalleye,...
