Oceanic whitetip sharks Carcharhinus longimanus are a cosmopolitan epipelagic species that was once prolific throughout the tropics and subtropics but was recently listed as Critically Endangered by the International Union for the Conservation of Nature and as Threatened under the United States Endangered Species Act. As such, relatively little is known about their habitat use, movement, and life history during migration. In her recent study entitled "Inferring Life History Characteristics of the Oceanic Whitetip Shark Carcharhinus longimanus From Vertebral Bomb Radiocarbon", Michelle presents bomb radiocarbon analyses of vertebral growth bands for archival specimens of C. longimanus from the western North Atlantic Ocean. Her tudy demonstrates that Δ14C patterns in vertebrae can serve as a multi-purpose tool for life history studies of oceanic sharks.
