The dolphin with the artificial fin

February 17, 2007 3:54 AM

An artificial fin has given a bottlenose dolphin a new lease on life. Fuji, a dolphin at Okinawa's Churaumi Aquarium, lost 75 percent of her flukes to an unknown disease. But a prosthetic fin developed by Bridgestone Corporation engineers has enabled Fuji to swim again in the aquarium's dolphin lagoon. Watch the BBC video report here. Read the aquarium's notes on the project and see photos of Fuji both during and after the disease's onset here.

Wait, what?

Since dolphins don't have lawyers, this is probably a good market for Bridgestone to enter.

They don't have lawyers, do they?

Hey, maybe once the dolphin taken to its new fin and it's all better, they can release it into the wild, then hack it to death.

Okinawa is quite distinct from Japan culturally, flapjax, and is not part of that dolphin drive. Those hunts take place on the mainland.

Lots of people are unaware that Okinawa wasn't even part of Japan until being forcibly annexed in the late 19th century, but conflating Okinawan practices with Japanese practices is often a big mistake. The history and culture is very different.

Very good point, jeffmshaw, and in fact I'm well aware that Okinawa and Japan are distinct entities. I was also well aware that my comment wasn't exactly a fair one, for the reason you've mentioned, and also for the reason that we're talking marine biologists here, and many of them are against the dolphin drives. On the other hand, many of the dolphins in aquariums around Japan, Okinawa and elsewhere are quite likely culled from the same dolphin drives, as some of the dolphins from those are spared the grisly hacking death and sold to aquariums.

Q: "how come we help dolphins but not poor kids in Iraq"?
A: Because the world is unjust.

If you watch the video, the dolphin looks at least as mobile without the prosthesis attached..

Video in the first link, that is. I watched the Reuters video too, and I can't tell if any of the jumping dolphins at the beginning are Fuji or not.

Heh.. They acknowledge that it isn't working that well yet here:

Fuji became able to jump strongly and touch the target with the cowling model. Now she can also do high jumps. We are planning to start training for measuring her swimming speed.

Future Plans
So far we have developed several versions of the artificial fin. However, the newest version is not yet perfect. We still continue our research for better materials and way of attachment. We are still trying out new ideas.

It certainly is a very interesting effort, well worth the attempt. It does seem like yet another case of bad science reporting though.

I somehow suspect the involvement of the world's tallest man in this one. I'm not sure how, but I'll get to the bottom of it...

Dolphins are able to distinguish 'self' in mirrors, right? I wonder if it feels more intact, as in having a better self-body image, with the prosthesis as opposed to without it?

They don't have lawyers, do they?

They don't in the US since they have no legal standing.

I don't know about Japan and Okinawa, but I doubt it.

I sort of like the fact that the feel-good story about a dolphin getting a prosthetic limb has links on the same page to an elephant losing it's temper and destroying a car. I'm not sure why this pleases me. Perhaps it's the idea that the elephant is thinking 'Sure, the fucking dolphin gets all this attention. Ohh, look at me, I can swim again. Here I am with this stupid human on my back playing polo. I hate polo. You know what? It's clobbering time...'

So kids, the lesson of the day is that prosthetic dolphins are cute and all, but don't piss off an elephant when your van is around. Seriously.

Elephants can get prosthetics too.

Two of my favorite pegleg critter tales:
- Tahi the Kiwi gets a new leg, courtesy of the Wellington Zoo, the Wellington Artificial Limb Board, and Peter Jackson’s Weta Workshop. It pays to be an iconic bird sometimes!
- A gull suffering from gangrene was saved by a passing ship, whose crew amputated the infected leg and replaced it with a gam and a hand cannibalized from a Barbie doll. As funny as I found this thought, the post-op photo is even better!

And I wouldn't dare speculate what that crew is going to do with a double-amputee Barbie....

This is awesome. Hooray for Fuji!
