Spinoloricus cinziae is an animal species described in 2014 in the phylum Loricifera.[1]

It is the first animal species described that does not require oxygen at any point during its life.[2][3][4] The species, along with two other newly discovered species, Rugiloricus nov. sp. and Pliciloricus nov. sp., were found in the sediment of the anoxic L'Atalante basin of the Mediterranean Sea.[3][4]

Electron microscope images[4] show that the species' cellular innards appear to be adapted for a zero-oxygen life. Their mitochondria appear to act as hydrogenosomes, organelles which provide energy in some anaerobic single-celled creatures.[5]

With a visual resemblance to tiny cups with tentacles sticking out, the species has been said to look like something out of a Dr. Seuss book.[5]
