New member Laurel Hamers (@Arboreal_Laurel) writes for the University of Oregon about the jet propulsion used by a gelatinous sea creature, Nanomia bijuga. Hamers describes how this tiny, colonial creature with no central nervous system nevertheless uses many distributed propulsion units to swim both quickly and efficiently. It can choose between different swimming modes depending on its needs, offering insights that could potentially inform the design of underwater vehicles, the scientists say. Image: M.
