Another shark swims toward extinction

The oceanic whitetip shark has almost disappeared from the Gulf of Mexico, according to new research from scientists at Dalhousie University. Once abundant throughout the world, oceanic whitetip (Carcharhinus longimanus) populations in the Gulf of Mexico have now dropped 99% or more over the last 60 years.

The research also found that silky shark populations have declined 90% in the Gulf of Mexico over the same time period.

Known for its abnormally large fins, the whitetip is highly prized for that most obscene of delicacies, shark fin soup. Tuna fishing has also taken a toll, as sharks get caught and killed in longline traps.
