Psychrolutidae
The fish family Psychrolutidae (commonly known as blobfishes, flathead sculpins, or tadpole sculpins) contains over 35 recognized species in 8 genera. This family consists of bottom-dwelling marine sculpins shaped like tadpoles, with large heads and bodies that taper back into small, flat tails. The skin is loosely attached and movable, and the layer underneath it is gelatinous. The eyes are placed high on the head, focused forward closer to the tip of the snout. Members of the family generally have large, leaf-like pectoral fins and lack scales, although some species are covered with soft spines. This is important to the species as the depths in which they live are highly pressurized and they are ambush/opportunistic/foraging predators that do not expend energy unless they are forced to. The blobfish has a short, broad tongue and conical teeth that are slightly recurved and are arranged in bands in irregular rows along the premaxillaries; canines are completely absent. Teeth are ...

Ebinania
''Ebinania'' is a genus of marine ray-finned fishes belonging to the Family (biology), family Psychrolutidae, the fatheads. These fishes are found in the Southern, Indian, Pacific and Atlantic Oceans. Description Ebinania is distinguished from other Psychrolutidae due to their thin, flexible orbital rim. Other features include prevomerine teeth. Species There are currently seven recognized species in this genus: * ''Ebinania australiae'' Keith L. Jackson & J. S. Nelson, 2006 Ebinania australiae was first discovered in 2006 off of the coast of southern Australia in a collection of 9 specimens. 8 of the specimens were found along the areas of Tasmania whereas the 9th sample were found near Perth, Southwest Australia. The species' appearance has a cirri on the head, durable thin and flexible orbital rims, cranial (frontal) arch 3 high and twisted upwards, prevomerine teeth in a continuous band, a single terminal chin pore, obsolete lateral line pores, and a pale color throughout the ...

Malacocottus
''Malacocottus'' is a genus of fatheads native to the northern Pacific Ocean. Malacocottus are typically occupied in the benthic zone near the bottom of the northern Pacific Ocean.

Dasycottus
The spinyhead sculpin (''Dasycottus setiger'') is a species of marine ray-finned fish belonging to the family Psychrolutidae, the fatheads. This species is found in the northern Pacific Ocean. This species is the only species in the monospecific genus ''Dasycottus''. Taxonomy The spinyhead sculpin was first formally described in 1890 by the American ichthyologist Tarleton Hoffman Bean with its type locality given as off Sitkalidak Island in Alaska. Bean classified this new species in a new monospecific genus, ''Dasycottus''. This genus is classified within the subfamily Psychrolutinae of the family Psychrolutidae. Etymology The spinyhead sculpin's genus name prefixes '' Cottus'', the type genus of the family Cottidae with ''dasys'' meaning "woolly", a reference to the cirri on the head and body which give this fish a bristly appearance. The specific name. ''setiger'' means "bearing hairs", another allusion to the cirri scattered over the head and body. Description The spinyhe ...

Blob Sculpin
The blob fish (''Psychrolutes phrictus'') or blob sculpin is a species of deep-sea fish of the family Psychrolutidae. It feeds mainly on crustaceans, molluscs, and sea pens. It lives off the continental shelves in very deep water (839–2800 m) in the North Pacific Ocean by the coasts of Japan, the Bering Sea, and California. When the female lays eggs the adult fish guard the nest. Description Maximum length is . The head is broad and flattened, the eyes are large and widely separated, and the mouth is curved with fleshy lips. There is no spine in front of the operculum (the bony flap that covers the gills), the branchiostegal membranes are fused to the isthmus (the fleshy projection separating the gill openings), and there are many small cirri (fleshy threads) scattered over the head and body. The operculum is poorly ossified and is covered by a gelatinous layer. Behind the head, the body tapers rapidly to the caudal peduncle and there is a gelatinous layer between the s ...

Albert Günther
Albert Karl Ludwig Gotthilf Günther , also Albert Charles Lewis Gotthilf Günther (3October 18301February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia ( Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen.
