Ophiodon elongatus (Girard 1854) is the extant lincod, a member of the scorpaeniformers restricted to the west coast of North America. This taxon is also basal to Seriola rivoliana (below) and kin. Nothe the extended 'cheek' bones creating an upper and lower fenestra. Also note the central and lateral cranial crests.

Seriola rivoliana (Valenciennes, 1833) is the extant Almaco jack or high-fin amberjack or longfin yellowtail. Not a sister to Seriola zonata, this species is basal to flying fish + opah, mahi-ahi and kin. Note the tall premaxilla, the high placement and deep coracoid of the pectoral fins as in Exocoetus and Lampris. Note the robust postorbital oriented posteriorly.

Labeotropheus fuelleborni (Ahl 1926; 30cm) is Fuelleborn's cichhlid, or blue mbuna, one genus of extant cichlid endemic to Lake Malawi in eastern Africa. These species are algae grazers. Here it nests with ocean-going Seriola zonata.

Conith and Albertson wrote, "Cichlids that hunt elusive prey typically pair slender, mobile oral jaws with gracile pharyngeal jaws, while cichlids that feed on algae or other tough foods typically pair robust, compact oral jaws with strong pharyngeal jaws."

Liparis florae (Linneaus 1766, Scopoli 1777) is the extant tidepool snailfish, a traditiional member of the Scorpaeniformes. Here it nests with Seriola rivoliana, the jack. Note the postorbital extends posteriorly, forming a 'cheekbone'.

Pseudoliparis swirei (Gerringer et al. 2017; 28cm; USNM 438975 / HADES 200060) is the extant Mariana snailfish. It lives in the deepest (8000m) ocean trenches. Note the reduction of the skull bones to mere struts as compared to Liparis. It eats crustaceans and has 1cm eggs. The pectoral fins produce a sucking disc for adhering to surfaces.

Andriashev and Pitruk (1993) define the genus Pseudoliparis as having "a well-developed disk and one pair of nostrils and lacking pseudobranchia and pleural ribs, with four radials in the pectoral girdle, which has neither notches nor fenestrae."

Anomalops katoptron (Kner 1868; 35cm) is the extant splitfin flashlightfish, a type of jack. Anomalops has a light organ (filled with luminious symbiothic bacteria blinking 90x a minute by moving the cover) beneath the large eyeball. That's how it detects its prey, zooplankton. Teeth are extremely tiny. Anomalops nests basal to the jack, Seriola.
