The Illuminating Reason Perenema Curl Up Into a Ball

Watching this Peranema feels a bit like watching a cat waffling back and forth between whether or not it wants to take a nap. Sometimes the Peranema stretches, its body undulating into an elongated, indescribable geometry as its flagella twitch like whiskers. And then, sometimes, it curls up into a cozy circle, tucking one end into itself the way any feline friend you might know curls up around the perfect beam of sunshine.
