That’s what pops to mind when I look at Sebastian Hess’ photos of a kind of plump, violent, single-celled creature he collected from a pond rich in sphagnum moss in southern Germany. The shape-shifting amoebozoan cell, prowling for algal cells to attack, curls its long strand of a flagellum into an earringlike loop. Holding the loop steady, the cell somehow glides. Yet the loop doesn’t flick, lash or wave. “They look basically like tiny flying saucers,” Hess says.
Even long-known protists have allure as a form of microwildlife. Like big cats and polar bears, many of these charismatic microfauna deserve their own nature documentaries. Hess has helped film one of his longtime favorite protists, a kind of. This mildly pretty teardrop-shaped cell chases prey by shooting out a cartoonishly long swan neck that can stretch more than seven times the organism’s original body length.
Today’s protists are sorted into supergroups, which are branches bigger than the classic eukaryote kingdoms and give a broad and deep view of evolution. The Amorphea supergroup, for example, spans all animals and fungi plus some one-celled relatives including many amoebas. Thetoo, for all its serene UFO-like travel, is a fierce predator. When it finds algae to feed on, the gliding spaceship becomes an attack amoeba.
In a diagram developed by Taylor, the sides of a doughnut rise through the hole, over the rim and wrap around the other side for another slide into the middle. At first, Hess could tell that his gumdrop cell clearly spun, but looking at the flagellum’s skimpy doughnut-shape with plain microscopy, “you cannot see any movement,” he says.
