PORTLAND, Ore. (AP) — Invasive bullfrogs have gobbled up 95 percent of Oregon spotted frogs in their Northwest range.
But researchers at Oregon Zoo have found one spot where the native frogs are staying one jump ahead.
Spotted frogs at Conboy Lake north of Hood River are surviving alongside the bigger bullfrogs.
Researchers noticed the "spotties" at Conboy Lake were a little harder to catch.
Zoo researcher Kyle Tidwell tested that with a high-speed camera. He found the Conboy Lake frogs had a significantly faster response time to a sudden threat than spotted frogs from the Puget Sound area.
The split-second may be the difference between survival and being a bullfrog's lunch.
