The armored searobin, Scalicus engyceros, was one of the fishes that famous ichthyologist David Starr Jordan, the original president of Stanford University, reported among the specimens floating offshore of a 1919 lava flow from Mauna Loa. This individual was seen during a dive on August 29, 2015, off Keahole Point, several miles north of the 1919 lava flow on the Kona Coast of Hawaii Island.
