2020 Small World in Motion Competition

Frank Fox’s second honorable mention in the 2020 Small World in Motion competition shows a Hydra, an invertebrate freshwater animal that is known for being able to expand its normal size. This video shows just such behavior as the creature stretches out many times its original length. This was taken using darkfield technique and clearly demonstrates Mr. Fox’s ability to keep moving subjects in focus, a challenge for even the most accomplished microscopist.
