Some sharks spend extended time periods in the protected waters of the Bahamas yet roam long distances when they leave
As the nations of the world prepare to vote on measures to restrict international trade in endangered sharks in early March, a team of researchers has found that one of these species – the oceanic whitetip shark – regularly crosses international boundaries. Efforts by individual nations to protect this declining apex predator within their own maritime borders may therefore need to be nested within broader international conservation measures.
A shark that swam from New Zealand to Fiji has returned home for Christmas, rounding off an 11,300km odyssey and amazed the scientists who tracked her journey.
In May, "Carol" became the first mako shark in New Zealand waters to be tracked with a satellite "spot" tag, under a Niwa research project funded by the Ministry for Primary Industries and Nova-Southeastern University in Florida.
Scientists watched in amazement as she set off for the Pacific Islands, only to change her mind halfway and turn back for a two-month stay near Ninety Mile Beach.
