Dolphins Protect Their Snouts With Sponges ~ By RANDOLPH E. SCHMID
WASHINGTON (AP) - A group of
dolphins living off the coast of
Australia apparently teach their offspring to protect their snouts with sponges while foraging for
food in the sea floor. Researchers say it appears to be a cultural behavior passed on from mother to daughter, a first for
animals of this type, although such
learning has been seen in other species.
The
dolphins, living in Shark Bay, Western
Australia, use conically shaped whole sponges that they tear off the bottom, said Michael Kruetzen, lead author of a report on the dolphins in Tuesday's issue of Proceedings of the National Academy of Science.
