A Predator at Work

I posted about a lake management study recently in which one of the featured players were Daphnia.

Daphnia have their predators, too, one of which is the phantom midge larvae. According to a recent report in Science (March 27, 2019) by Erik Stokstad the "predators—phantom midge larvae, also known as glassworms—are common in lakes worldwide. Now, scientists trying to learn how the neckteeth work have captured the first high-speed footage of a glassworm attack—and they have discovered that it is one of the fastest in the animal kingdom."

See the article with a short movie of a nasty looking predator at work. It reminds me of the predator in the 1986 movie Aliens.
