Soil bacteria that hunt like a wolfpack? Myxobacteria and their role in the food web

A photo of a wolf in the middle and four microscopic images of colourful bacterial cultures around it.

Picture this: bacteria that can slime their way around the soil, finding their prey, circling it, closing in on it and lysing it (or making their cell pop), just to feed on their prey. It sounds like a far stretch from a wolf to a bacteria, but even other soil predators, the comparably huge nematode worms ( up to 100 times bigger!), are afraid of these bacterial “wolves”.

The body’s face still held red hair and a beard, their teeth were well preserved, and a hoop of willow was wrapped around their throat. But this wasn’t the dry, hot climate of Egypt but a cold and rain-sodden bog of Ireland. Later assessment suggested that these were the remain ...[Read More]
