A trout eats shrews -- 19 of them -- and keeps them "well-preserved" in its stomach giving biologists quite a surprise when they were found. On Sept. 12, UPI reported that a rainbow trout was recently caught and gutted in Alaska and judging by its small size (about 48 centimeters), no one expected to find shrews never mind so many of them.
"I can’t say for certain that I’ve ever seen a well preserved shrew in a stomach analysis. No one ever thought they would pull 19 shrews out of it," explained fish biologist Mark Lisac.
When a trout eats shrews there are many questions to be asked. For starters, is it normal for a fish to eat the mouse-like creature. Interestingly enough, trout often dine on small mammals like shrews and voles according to the report. What was fascinating was that such a small fish could store such a large amount of shrews in its tummy.
"How did so many shrews make it into one trout? It's anyone's guess, but perhaps a nest by the river eroded, dumping all of the shrews into the water where this rainbow trout likely came away feeling like a lottery winner," read the post on the Togiak Refuge's Facebook page back in August. The rare find is just now making national news.
If a trout eats shrews, does that make humans eating trout less appetizing? What's really inside the fish you eat?
