Fowlerichthys radiosus

Fowlerichthys radiosus has a somewhat compressed, globose body with the large eyes placed on the sides of the head and a large upwardly pointing mouth with many small teeth. The small gill openings are located to the rear and below the base of the pectoral fin, which is limb-like with and elbow like joint and broad connection to the body. There are 3 dorsal spines and a dorsal fin which contains 13 soft rays. The first dorsal spine, the illicium is roughly equal in length to the second dorsal spine and is topped with a small esca which is a small folded oval. The second dorsal spine is not very curved and is connected to the skin on the head by a membrane. The third dorsal spine is moveable and is not connected to the skin on the head. The anal fin contains 9 soft rays, there is a caudal peduncle and the rear edges of the dorsal and anal fins are not connected to the caudal fin. The skin on the body has a dense covering of bifurcated spicules. The color of this fish is brown to beige, the anal, caudal and dorsal fins are sometimes barred/ The illicium is normally marked with pale bands. There is a single large ocellus on the upper body and the base of the dorsal fin and there are short dark lines radiating out from the eye. …

Fowlerichthys radiosus is found in the Western Atlantic Ocean from Long Island in New York south to Cuba and the Gulf of Mexico, and along the northern South American coast between Colombia and Surinam. It has also been reported from Madeira in the eastern Atlantic. The singlespot frogfish is found at depths between 20 and 275 m (66 and 902 ft) on offshore banks and the deeper waters of the continental shelf.

Fowlerichthys radiosus has the genus name Fowlerichthys which combines Fowler, honouring the American ichthyologist Henry Weed Fowler of the Academy of Natural Sciences of Philadelphia who gave Barbour the type specimen of the type species of the genus, F. floridanus, with ichthys, which means fish. The specific name, radiosus, means "rayed", a reference to illicium being twice as long as that of its presumed congener Antennarius tigris.
