The sea creature called the yokozuna slickhead fish had only been caught six times and was mainly unknown to scientists.  The sighting was reported first on June 1 in a study titled “Detection of the Largest Deep-Sea-Endemic Teleost Fish at Depths of Over 2,000 m Through a Combination of eDNA Metabarcoding and Baited Camera Observations,” published in Frontiers in Marine Science.
