Not that one. This one. (Complete with video, even!).
You might think a catfish on land would fare as well as an elephant on roller-skates, but a new study reveals they slither around and adeptly catch insect meals.
The finding helps scientists imagine how ancient fish made their first hunting…
Looks like the European Wels. I am amazed that they have never been introduced into the US (so far as I know).
It is indeed the European Wels. It is considered to be introduced in western Europe because its "original" range did not include that. But since there is no major biogeographical barrier between its traditional range and the new range other than land bewteen rivers being barriers, it is not all that invasive. But it was probably put there by anglers.
