Hind flippers

Whatever happened to that dolphin that was caught in Japan with the hind flippers? It was a big thing and then just disappeared.

Was it taken into captivity?

Yeah, the Taiji Whaling Museum took the dolphin.

I found this on their site. Of course, the copyright year for the site ends in 2006, the same year the dolphin was caught. And the only text I find about it on the site says it was captured in October 2006.


More images found on their site.

And these were found in a google search.
From December 2007
November 2007. The second two are possibly her. According to the blog post, and a link back to Taiji, they held a naming contest.

I'm confused in the picture in the first batch of her, mouth she has all these chips on the upper part of her beak, but in the lower pics she doesn't :/
Nice finds! I never saw anymore then the capture pictures.

I said the second two were possibly her. They were posted along with the shot of the hind flippers. They may not be her.

That's really cool. I only saw the pictures where they hold her belly up, to see the hind flippers. So the other pictures are all new to me, including the capture pictures! Thanks for sharing these!

I didn't know Taiji Whale Museum had a pool with underwater viewing for their dolphins, like a tunnel... I thought it was Hakkejima Seaparadise that only had that. But they will probably have shared the concept ;-) This is nice, though, because it allows for nice views of the animals underwater, especially for this particular dolphin. That first underwater picture is amazing!

Oh, nice! Thanks for all the pictures =D

I had no idea where she went or anything.

I've been looking for more information on the structure of the flippers, but so far can't find anything. I'd really like to know if they've done x-rays or sonograms to see if there are bones or something (it really looks like a smaller version of the pectoral flippers). Part of me wonders if there's a possibility that it's the remains of an undeveloped twin - not sure how viable that notion is, but I've seen pictures of people with extra legs coming out of their torso due to just that.

Could this just be that a certain gene during development just didn't get "turned off" at the right time? It could be that all cetaceans still carry the gene to have hind limbs, but it's "turned off" at a certain time.

That wouldn't be surprising. That's how some humans end up being born with tails.

At least we know when they're happy... Kidding.

But yeah, that's definitely a viable explainaition. I just wonder how much had to go wrong for that gene to get turned on. Most genes are connected, so I wonder if this dolphin maybe has some health problems; for example, people born with cleft pallettes often have heart defects.

Hmm, that sounds plausible. I don't know if this happens during fetal development of all species, but for some at least, cetaceans have hind limbs in utero. Your idea would make sense in that case. I don't think anything so perfectly symmetrical has been seen before, though.

Meh, what I'd give to see an x-ray of those things. =P

I wonder if she'll have any offspring, and if this will show up in a 2nd or 3rd generation.

Perhaps there's some way to contact TWM? I think that a university in Japan was planning on studying her. It would be great to find some way to get information on her.

And just curious, but what other cetaceans have been found with hind appendages or have there been any?

These were posted on another forum and apparently taken in October.
