Giant Monster Slugs and Gobsmacked Scientists



We’ve talked about rampaging Latvian beavers, ‘roid raging kangaroos and even toilet iguanas here at And Then It Got Weird, but we have yet to address the scourge of giant predatory slugs.

 Monster slugs are devouring defenceless baby birds in nests

“The actual moment of slugs predating on nestlings isn’t easy to observe,” says Katarzyna Turzańska at the University of Wroclaw in Poland. “You are  more likely to come across the traces of the ‘tragedy’: dead or alive nestlings with heavy injuries, covered in slime – and often slugs’ droppings found nearby.”

She and Justyna Chachulska, a colleague at the University of Zielona Góra in Poland, were studying common whitethroat birds near Wroclaw, in Poland, when they spotted a slug of the Arion genus in a nest with newly hatched chicks. The next day, the slug was gone, and the chicks were dead with severe injuries on their bodies that hinted at the slug as the culprit.

They were gobsmacked. “We couldn’t believe that the slug had killed the nestlings,” says Turzańska. “We talked to many experienced ornithologists, but none of them had observed slug predatory behaviour towards birds before.”

Gadzooks! Not gobsmacked!

Note that only “defenseless” baby birds were devoured. Those trained in Krav Maga were less prone to slug attacks.

Be careful, you could be next.


By the way, the entire 1988 horror movie “Slugs” is available on YouTube. For science.

Harriet Tubman is one of America’s most beloved historical figures but has sadly been largely relegated to just a few facts during Black History Month. This incredible ex-slave, spy, cook, nurse, public speaker and rescuer deserves a story worthy of her stature.

“Minty” – tentatively titled after Tubman’s nickname – is a “reimagining” of Harriet Tubman as an action hero. It is a period piece with a modern flare.
