This amoeba eats prey like owls do
The microscopic predator engulfs algae, drains the cells and spits out the shell

The amoeba Strigomyxa ruptor (large yellow-orange cell) engulfs its prey, a Closterium alga (elongated green cell). Unlike all known protists, the amoeba splits open its prey, extracts and consumes the innards, and ejects the undigested cell walls.
