Chaunax coloratus (Lowe 1846 Chaunax sitkusi shown in photo) is the extant sea toad or coffinfish. Sometimes called an angler. Here it nests with the frogfish, Antennarius. A small lure is present.

Antennarius pictus (Daudin 1816 originally Lophius pictus Shaw 1794, 20cm) is the extant frogfish, a bottom-dwelling sit-and-wait predator with a lure and an enormous gape. The pelvic fins are anterior to the pectoral fins. Both are used to walk on the sea floor. Note the separation of the parietals by the postparietals. Antennarius is basal to Himanotolophus (above).

Neilpeartia ceratoi (Carnevale et a. 2020, Eocene, 6cm in length) is a tiny early frogfish.

Ogcocephalus vespertilio (Linneaus 1758; 30cm) is the extant Brazilian batfish or seadevil. Here it nests with frogfish, like Antennarius. Gregory labeled a parietal, but that is the posterior frontal, which also extends anteriorly. No nasals are visible in this diagram. The pelvis is anterior to the pectoral girdle. This nocturnal fish covers itself with sand and preys on seafloor invertebrates. The rostrum can be used as a digging tool.
