A species of earthworm commonly referred to as a ‘jumping worm’ has made its way to North America, namely the Asian jumping worm (Amynthas agrestis), and its introduction into California’s habitats has caused concern for the ecosystem. Asian jumping worms get their name from their ability to leap as high as a foot into the air. They also have a general tendency to squirm and flail around when disturbed, which is typically when they will also jump: it is a defense mechanism they use to get away from predators. The Minnesota Department of Resources uploaded a “YouTube video about jumping worms” which shows the worms’ erratic behavior.
