A female great white shark named Nicole after actress Nicole Kidman crossed the Indian Ocean twice in a nine-month period, traveling roundtrip between South Africa and Australia. This is the first transoceanic return trip ever documented in sharks, and the fastest such voyage on record for any marine organism. Researchers describing the finding in the current issue of Science further note that Nicole is the first physical link found between two important and far-flung shark populations, and that these animals may be more vulnerable to commercial fishing in the open ocean than previously believed.
