Etymology: Dascyllus: Greek, daskillys, -on = a kind of fish (Ref. 45335).
Eponymy: Donald W Strasburg (1925–2008) was a fish ecologist at the University of Hawaii and at the Bureau of Commercial Fisheries Biological Laboratory, Honolulu and an environmentalist at the Naval Research Laboratory, Washington, DC. [...] (Ref. 128868), visit book page.

Adults inhabit coral and rocky reefs. The two specimens at the Bishop Museum were collected off Matahumu Point, Patu Hiva, Marquesas Islands in 6 to 12 meters (Ref. 7247). Feeds on zooplanktons (Ref. 89972). Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 113699).
