Greeneyes are deep-sea aulopiform marine fishes in the small family Chlorophthalmidae. Thought to have a circumglobal distribution in tropical and temperate waters, the family contains just 18 species in two genera. The family name Chlorophthalmidae derives from the Greek words chloros meaning "green" and ophthalmos meaning "eye".
The family Torpedinidae contains 22 species of electric rays or torpedoes, flat cartilaginous fishes that produce electricity as a defense and feeding mechanism. They are slow-moving bottom-dwellers.
Antigonia is a genus of marine ray-finned fish belonging to the family Caproidae, the boarfishes. This genus is found in the warmer oceans around the world and is the only extant genus in the subfamily Antigoniinae.
Squalus is a genus of dogfish sharks in the family Squalidae. Commonly known as spurdogs, these sharks are characterized by smooth dorsal fin spines, teeth in upper and lower jaws similar in size, caudal peduncle with lateral keels; upper precaudal pit usually present, and caudal fin without subterminal notch. In spurdogs, the hyomandibula is oriented at a right angle to the neurocranium, while in other sharks, the hyomandibula runs more parallel to the body. This led some to think that the upper jaw of Squalus would not be as protractile as the jaws of other sharks. However, a study that compared different jaw suspension types in sharks showed that this is not the case and that Squalus is quite capable of protruding its upper jaw during feeding.
Apristurus is a genus of catsharks, the family Scyliorhinidae, commonly known as the ghost or demon catsharks.
Etmopterus is a genus of lantern sharks in the squaliform family Etmopteridae. They are found in deep sea ecosystems of the Atlantic, Indian and Pacific Oceans.
Torpedo is a genus of rays, commonly known as electric rays, torpedo rays, or torpedoes. They are slow-moving bottom-dwellers capable of generating electricity as a defense and feeding mechanism.
Epigonus is a genus of fish in the family Epigonidae found in the Atlantic, Indian and Pacific Ocean. The genus was erected by Constantine Samuel Rafinesque in 1810.
Glossanodon is a genus of fishes in the family Argentinidae.
Dolichopteryx is a genus of barreleyes.
Aulopus is a genus of flagfins native to the Atlantic Ocean and the Pacific Ocean. Although Aulopus is native to both the Atlantic and the Pacific oceans, for the first time in 2010 Aulopus filamentosus, was spotted in Brazilian waters. A discovery like this may suggest that these fish can be found in new environments.
Hime is a genus of flagfins native to the eastern Indian Ocean and the western Pacific Ocean.
Melamphaes is a genus of fish in the family Melamphaidae found in Atlantic, Indian and Pacific Ocean.
Poromitra is a genus of ridgeheads. The 22 known species of Poromitra have been divided into five species groups according to variation in preopercle anatomy.
Pentaceros is a genus of marine ray-finned fish, armorheads from the family Pentacerotidae. They are native to the Pacific, Indian, and eastern Atlantic Oceans. Pentaceros is the only genus in the monotypic subfamily Pentacerotinae.
The short beard codling is a species of marine bony fish in the family Moridae. Native to the western Atlantic Ocean, it is found on the continental slope at depths between 50 and 1,620 m.
Merluccius senegalensis, the Senegalese hake, is a species of fish from the family Merlucciidae, the true hakes. It is found in the sub tropical waters of the eastern Atlantic Ocean off the north western coast of Africa.
Ceratothoa steindachneri is an ectoparasite known as a tongue biter. It parasitises fish by attaching to the tongue, causing atrophy. It then replaces the tongue.
Nikolai Vasilyevich Parin was a Soviet and Russian ichthyologist, specializing in oceanic pelagic fish. He headed the Laboratory of Oceanic Ichthyofauna at the RAS Institute of Oceanology in Moscow, where he ended his career as a Professor after more than fifty-seven years. In his career, he described more than 150 new taxa of fish and participated in 20 major oceanic expeditions. Thirty-six species of fish are named in his honour.
Chlorophthalmus basiniger is a fish species that is in the genus Chlorophthalmus which was discovered in Vietnam by Prokofiev & D. Pauly in 2020.
