Orangutan makes a run for it at Australian zoo


ADELAIDE, Australia — A zoo in Australia was evacuated Sunday after an "ingenious" 137-pound (62-kilogram) orangutan short-circuited an electric fence and hopped a wall surrounding her enclosure.

The ape, a 27-year-old female named Karta, jammed a stick into wires connected to the fence and then piled up debris to climb a concrete and glass wall at the Adelaide Zoo.

Zoo curator Peter Whitehead told reporters Karta sat on top of the fence for about 30 minutes before apparently changing her mind about the escape and climbing back into the enclosure.

"I think when she actually got out and realized where she was ... she's realized she shouldn't be there so then she's actually hung onto the wall and dropped back into the exhibit," Whitehead said.

Karta came within a few yards (meters) of visitors, who were the first to notice the animal's escape bid.

Whitehead said the animal was not aggressive, but the zoo was cleared as a precaution, and veterinarians stood by with tranquilizer guns in case of trouble.

"You're talking about an animal that's highly intelligent," Whitehead said. "We've had issues with her before in normal day-to-day operations where she tries to outsmart the keepers. She's an ingenious animal."

Officials at the zoo in the southern city of Adelaide would conduct a "thorough review" of the escape bid and it was likely some vegetation that could be used in a future try for freedom would be removed from Karta's enclosure.

Fla. Student Suspended from Bus for Passing Gas

LAKELAND, Fla. (AP) -- An eighth-grader was suspended from riding the school bus for three days after being accused of passing gas. The bus driver wrote on a misbehavior form that a 15-year-old teen passing gas on the bus Monday to make the other children laugh, creating a stench so bad that it was difficult to breathe. The bus driver handed the teen the suspension form the next day.

Polk County school officials said there's no rule against flatulence, but there are rules against causing a disturbance on the bus.

The teen said he wasn't the one passing gas.

Whether he did it or not, he might have gotten off easy. A 13-year-old student at a Stuart school was arrested in November after authorities said he broke wind in class.

Dolphins are capable sea chefs, scientists say


CANBERRA (Reuters) – Dolphins are the chefs of the seas, having been seen going through precise and elaborate preparations to rid cuttlefish of ink and bone to produce a soft meal of calamari, Australian scientists say.

A wild female Indo-Pacific bottlenose dolphin was observed going through the same series of complicated steps to prepare cuttlefish prey for eating in the Spencer Gulf, in South Australia state.

"It's a sign of how well their brains are developed. It's a pretty clever way to get pure calamari without all the horrible bits," Mark Norman, the curator of mollusks at Museum Victoria and a research team member, told the Canberra Times newspaper.

The research team, writing in the science journal PLoS One, said they repeatedly observed a female dolphin herding cuttlefish out of algal weed and onto a clear, sandy patch of seafloor.

The dolphin, identified using circular body scars, then pinned the cuttlefish with its snout while standing on its head, before killing it instantly with a rapid downward thrust and "loud click" audible to divers as the hard cuttlebone broke.

The dolphin then lifted the body up and beat it with her nose to drain the toxic black ink that cuttlefish squirt into the water to defend themselves when attacked.

Next the prey was taken back to the seafloor, where the dolphin scraped it along the sand to strip out the cuttlebone, making the cuttlefish soft for eating.

Norman and study co-author Tom Tregenza, from the University of Exeter, said the behavior exhibited between 2003 and 2007 was unlikely to be a rarity.

"In addition to our observations, individual bottlenose dolphins feeding at these cuttlefish spawning grounds have been observed by divers in the area to perform the same behavioral sequence," they said in the study.

"The feeding behavior reported here is specifically adapted to a single prey type and represents impressive behavioral flexibility for a non-primate animal."

A separate 2005 study provided the first sign dolphins may be capable of group learning and using tools, with a mother seen teaching her daughters to break off sea sponges and wear them as protection while scouring the seafloor in Western Australia.

The mammals used the sponges "as a kind of glove" while searching for food, University of Zurich researcher Michael Krutzen told New Scientist magazine.

Other researchers have observed dolphins removing the spines from flathead fish prey and breaking meter-long Golden Trevally fish into smaller pieces for eating.
