Chaunax suttkissi, the pale-cavity gaper, spotted frogmouth, spotted gaper or Sutkus sea toad, is a species of marine ray-finned fish belonging to the family Chaunacidae, the sea toads. This species is found in the Atlantic Ocean.
Chaunax suttkisi was first formally described in 1989 by the American ichthyologist John H. Caruso with its type locality given as off Venezuela in the Caribbean Sea at 11°40'N, 62°33'W, at a depth of 585–622 m (1,919–2,041 ft). [2] Within the genus Chaunax this species is placed in the Chaunax fimbriatus species group. [3] The genus Chaunax is one of two genera classified by the 5th edition of the Fishes of the World within the family Chaunacidae, the sea toads. The sea toads are placed within the monotypic suborder Chaunacoidei within the anglerfish order Lophiiformes. [4]
Chaunax, the genus name, means "one who gapes", from chanos meaning "to gape", an allusion to the large, wide mouths of these fishes. The specific name suttkusi, honours Royal D. Suttkus, an ichthyologist at Tulane University for his contributions to ichthyology and the extensive collection of fish specimens he collated during his career at the university. [5]
Chaunax suttkusi has a globular, slight compressed body which tapers to a small, rounded caudal fin. The large head is somewhat cuboid with small eyes which are covered in transparent skin. The large, oblique mouth is equipped with many small, thin, sharp vertical teeth and the gill opening is small. Of the three dorsal spines, two are embedded in the skin on the nape and only the first, the illicium is visible. The illicium is tipped with a lure, or esca which is a mop-like tuft of filaments. The illicium is lowered into a flat, concave depression on the snout when not being used to attract prey. The dorsal fin is on the rear of the body and contains between 10 and 12 soft rays while the anal fin has 6 or 7 soft rays. The loose, flabby skin has a dense covering of robust denticles. The lateral line is open and runs from the caudal peduncle to the head, with obvious canals connecting to branches under the eye, on the chin and along the lower flanks. The main part of the lateral line on the upper body contains between 29 and 42 pores with between 11 and 13 pores on the head. The overall colour is pale pink to rosy pink, with red on the top and sides of the head and fins and the undersides of both the head and body are whitish. The cavity on the snout for the illicium is pale while the illicium and esca are uniform in color, varying from pale through to dusky with the filaments of the esca being black. [6] This species has a maximum published total length of 26.7 cm (10.5 in) and a maximum published weight of 359 g (12.7 oz). [7]
Chaunax suttkusi is found in the Atlantic Ocean. In the eastern Atlantic it occurs from Ireland south as far as Angola, its range includes the Azores, while in the western Atlantic it can be found from South Carolina as far south as the Rio Grande Rise. [1] It has also been found in the Mediterranean Sea. [8] The range of this species is thought to be extending northwards due to increasing temperatures as a result of climate change. [1] This is a bathydemersal species found at depths between 220 and 1,060 m (720 and 3,480 ft) [7] on soft bottoms on the continental shelf. [1]
Goosefishes, sometimes called anglers or monkfishes, are a family, the Lophiidae, of marine ray-finned fishes belonging to the order Lophiiformes, the anglerfishes. These fishes are found in all the world's oceans except for the Antarctic Ocean.
The sea toads and coffinfishes are a family, the Chaunacidae, of deep-sea ray-finned fishes belonging to the monotypic suborder Chaunacoidei within the order Lophiiformes, the anglerfishes. These are bottom-dwelling fishes found on the continental slopes of the Atlantic, Indian, and Pacific Oceans, at depths to at least 2,460 m (8,070 ft). There have also been findings of deep-sea anglerfishes off the coasts of Australia and New Caledonia. Other findings suggest some genera of Chaunacidae are found near volcanic slopes encrusted with manganese. Of the two genera in the family, Chaunacops are typically found at deeper depths than Chaunax, but with considerable overlap between the two genera.
The ocellated frogfish is a species of marine ray-finned fish belonging to the family Antennariidae, the frogfishes. This fish is found in the Western Atlantic Ocean.
The pink frogmouth, or redeye, pink gaper or uniform gaper, is a species of marine ray-finned fish belonging to the family Chaunacidae, the sea toads. This species is found in the Atlantic Ocean.
Glauert's anglerfish is species of marine ray-finned fish belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. This species is the only species in the monospecific genus Allenichthys. This species is endemic to southern Australia.
The redeye gaper, Chaunax stigmaeus, is a sedentary species of anglerfish in the family Chaunacidae. It is native to deep waters in the western North Atlantic from the Georges Bank off New England southward to the Blake Plateau off South Carolina. The species is found on the outer continental shelf and upper continental slope at a depth of 90–730 m and among dense beds of dead coral rubble, their preferred habitat. The original type specimen was caught in a trawl off Atlantic City on March 1, 1946, and donated to the Academy of Natural Sciences by Carroll B. Atkinson. The name stigmaeus means "speckled" in Greek. This species is a member of the C. pictus species complex.
Chaunax, variously known as coffinfishes, gapers or frogmouths, is a genus of marine ray-finned fishes, it is one of two genera belonging to the family Chaunacidae, the sea toads. They are found in tropical and subtropical oceans around the world typically in deep water.
