Armed and dangerous - Flipper the firing dolphin let loose by Katrina

It may be the oddest tale to emerge from the aftermath of Hurricane Katrina. Armed dolphins, trained by the US military to shoot terrorists and pinpoint spies underwater, may be missing in the Gulf of Mexico.

Experts who have studied the US navy's cetacean training exercises claim the 36 mammals could be carrying 'toxic dart' guns. Divers and surfers risk attack, they claim, from a species considered to be among the planet's smartest. The US navy admits it has been training dolphins for military purposes, but has refused to confirm that any are missing.

Dolphins have been trained in attack-and-kill missions since the Cold War. The US Atlantic bottlenose dolphins have apparently been taught to shoot terrorists attacking military vessels. Their coastal compound was breached during the storm, sweeping them out to sea. But those who have studied the controversial use of dolphins in the US defence programme claim it is vital they are caught quickly.

Leo Sheridan, 72, a respected accident investigator who has worked for government and industry, said he had received intelligence from sources close to the US government's marine fisheries service confirming dolphins had escaped.

'My concern is that they have learnt to shoot at divers in wetsuits who have simulated terrorists in exercises. If divers or windsurfers are mistaken for a spy or suicide bomber and if equipped with special harnesses carrying toxic darts, they could fire,' he said. 'The darts are designed to put the target to sleep so they can be interrogated later, but what happens if the victim is not found for hours?'

Usually dolphins were controlled via signals transmitted through a neck harness. 'The question is, were these dolphins made secure before Katrina struck?' said Sheridan.

The mystery surfaced when a separate group of dolphins was washed from a commercial oceanarium on the Mississippi coast during Katrina. Eight were found with the navy's help, but the dolphins were not returned until US navy scientists had examined them.

Sheridan is convinced the scientists were keen to ensure the dolphins were not the navy's, understood to be kept in training ponds in a sound in Louisiana, close to Lake Pontchartrain, whose waters devastated New Orleans.

The navy launched the classified Cetacean Intelligence Mission in San Diego in 1989, where dolphins, fitted with harnesses and small electrodes planted under their skin, were taught to patrol and protect Trident submarines in harbour and stationary warships at sea.

Criticism from animal rights groups ensured the use of dolphins became more secretive. But the project gained impetus after the Yemen terror attack on the USS Cole in 2000. Dolphins have also been used to detect mines near an Iraqi port.

Alright, listen up, people. Our fugitive has been on the run for ninety minutes. Average swim speed in murky water barring injuries is 8 knots. That gives us a search radius of fourteen miles. What I want from each and every one of you is a hard-target search of every sand bar, sea cave, ship wreck, swimming pool, and toxic dart shop in that area. Checkpoints go up at fifteen miles. Your fugitive's name is Flipper. Go get him.

Nope, the Observer is a genuine Sunday newspaper.

I think the Observer is a tabloid in the US but real in the UK. Either way, the story is funny as hell.

Hey, I was listening to "wait, wait, don't tell me" on NPR and they mentioned something about someone taught dolphins to sing the theme to Batman. Anyone see anything about that in the news?

"singing the theme to Batman"... isn't that something like singing Pomp and Circumstance?

Dolphins
Dolphins are the only mammals other than humans to recognise rhythms and reproduce them vocally (Image: iStockphoto)
Scientists have taught dolphins to combine both rhythm and vocalisations to produce music, resulting in an extremely high-pitched, short version of the Batman theme song.

The findings, outlined in two studies, are the first time that nonhuman mammals have demonstrated they can recognise rhythms and reproduce them vocally.

"Humans are sensitive to rhythms embedded in sequences of sounds, but we typically consider this skill to be part of processing for language and music, cognitive domains that we consider to be uniquely human," says Professor Heidi Harley, lead author of both studies.

"Clearly, aspects of those domains are available to other species."

The studies will be presented at the joint meeting of the Acoustical Society of America and NOISE-CON 2005, which runs from 17 to 21 October in Minneapolis.

Learning to sing

Harley, who is associate professor of social sciences at the New College of Florida in Sarasota, says that both studies tested dolphins at Disney's Epcot Center in Florida.

The researchers first had an adult male bottlenose dolphin position itself in front of an underwater sound projector, called a hydrophone, that produced six different 14 kiloherz, 4 second rhythms.

The dolphin was rewarded for performing a certain behaviour to each rhythm. For example, when rhythm 1 played, it waved its pectoral fin and when rhythm 2 played, it tossed a ball.

The various rhythms were played at different frequencies and tempos to ensure the dolphin was recognising rhythms instead of just frequencies or sound durations.

Another adult male was trained to produce similar rhythms using a pneumatic switch, essentially a small, air-filled ball connected to a computer that then generated sounds whenever the dolphin pressed the switch.

"The dolphin was reinforced for producing a specific rhythm to a specific object," says Harley.

"For example, when we presented him with a Batman doll, he received a fish for producing a specific rhythm, in this case, a short sound and then a long one."

"If you recall the original Batman TV series musical intro you'll probably remember the way they sang 'Bat-maaaaaaaan'," she adds.

The dolphin spontaneously vocalised to the rhythms, so the researchers started to reward the male with fish whenever it matched its 'singing' to the rhythms.

By the end of the studies, the scientists could show an object, such as the Batman doll, which represented a certain rhythm-vocalisation combo to the dolphin, and it would create the correct sounds both vocally and using the switch.

Batmaaaaaaan

Gordon Bauer, associate professor of psychology at the New College of Florida who did not work on the studies, says, "This is the first report, to my knowledge, of a nonhuman mammal's ability to discriminate rhythmic patterns."

But Bauer doubts that dolphins realise they are producing what people consider 'music'.

"I think music is a human construct," he says. "I doubt that it has pertinence to animals, although the elements of music, such as pitch, time, timbre, rhythm, etc, may be incorporated into animal communication."

Harley agrees, and hopes the everyday vocalisations of dolphins will be analysed in terms of their rhythmic content.

In the near future, she and her team are planning to test the dolphins on their ability to recognise recordings of their own rhythms by having them associate their own sound creations with identifying objects similar to the Batman doll.

I'm sure some dog owners have got their pets to bark in various ways on command or howl in time to a piece of music. I'm not sure how this dolphin trick is any different.
