Meteora sporadica is a mysterious free-living protozoan discovered in 2002 during sampling at a depth of 1,230 meters below sea level in the Sporades Basin, part of the Mediterranean Sea.

[1] It was placed as Eukaryota incertae sedis due to its unique morphology unlike any other group of protists.

[1] Two decades later, a 2022 phylogenetic analysis of Meteora still was not able to solidly relate it to any known group of eukaryotes, suggesting that it could be a new high-level eukaryotic group.

[3] The cell body is colorless and ovular.

The lateral appendages move independently of each other in a rowing motion.
