Microbes are not just blobs. They are very well-evolved biological machinery, the product of eons of evolution that have exposed their ancestors and them to different homes and food and threats.

Why Do Microbes Explode Under UV Light?

The microcosmos is not always a graceful space. Sometimes an organism just needs to get around the way it gets around, even if that means looking like a swimming elephant head with a truncated snout at one end and a rat tail at the other.
