Otters have been reintroduced to Indiana waterways, hurray! Pretty successfully, too; DNR says only 20% of Indian's counties are otterless. A big win for the environment, right?
...Except ottering is a high-energy activity. Otters having perfectly good legs, they've discovered that the many, many stocked* fishing ponds in Indiana are a kind of otter buffet; or, as a commenter put it, "They are nothing but fresh water sharks eating everything in their path."
(This can only end when they introduce tigers to deal with whatever they've introduced to control whatever it was they brought in to keep the otters in check; I heard that tune as a child!)
* All native fish, are they?
