SOME efforts to save endangered species are controversial, some are praiseworthy, and others approach the absurd. One citizen-led effort underway in the hot springs town of Yufuin, Oita, however, is quite reasonable and isn’t causing problems for anyone.
The endangered species in question is a rare variety of the stenothyridae shellfish. This particular variety is the only shellfish in the world whose natural habitat is a hot springs, and it exists only in Yufuin. It also was found in several nearby areas, including the well-known spa resort city of Beppu, until the mid-1960s.
But the shellfish started disappearing when some of the hot springs water was diverted to resorts — the exact cause and effect has never been identified —- and it now lives only in a water course near Lake Kinrin. The water temperature there is roughly 36° C (96.8° F) year-round.
Some local people formed a research group in February to expand its habitat. They succeeded in tripling the local population in just three months. They’ve also kept some alive in tubs of heated water to show school children. That was enough to convince the prefecture and city governments to provide a modest amount of funding, and the group is now conducting water quality tests in different locations to find the most suitable spots that might work as a new home.
Give them credit for even knowing about the creature to begin with. It’s naturally a bright gold color, but it eats moss and usually winds up covered in the stuff. It’s also only 4 x 2.5 millimeters in size, which works out to 0.15 x 0.09 inches. You’ve really got to be looking for it to find it.
If you’re ever in the neighborhood and enjoy soaking in hot water, by the way, Yufuin’s an excellent choice. I’ve been there twice and would find it very easy to live there year-round if it came to that. It’s a small town near the mountains, and it’s quite attractive as the picture above shows. (The photo is from a Japanese website called Muru’s Log.) The main street is perfect for walking, has excellent views, and is filled with the sort of shops that women like. And the stenothyridae are so small you won’t even notice them sharing space with you in the spa.
There’s also a song called Yufuin. It’s about a woman trying to recover from an unhappy love affair.
