Around 30 Dolphins Beached on Brazilian Shore

Not sure how they got there

Around 30 large dolphins ran aground early Sunday on the shallow sands of Upanema beach in Areia Branca, in northeastern Brazil. At least seven of them had died, according to news reports.

It was not immediately known why the animals beached themselves, but biologists were examining whether the pod leader might have been ill. Another hypothesis is that the dolphins were pursuing a school of fish and were trapped on Upanema's high sand banks.
