Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Black Dogfish
The black dogfish (''Centroscyllium fabricii'') is a species of dogfish shark in the family Etmopteridae. It is common over the outer continental shelf and continental slope at depths of . Females generally inhabit deeper water than males, and depending on the region, smaller sharks may occur at different depths than larger ones. This species is distributed widely in the Atlantic Ocean, from Greenland and Iceland to Virginia and West Africa in the north, and off southwestern Africa and Argentina in the south. The largest member of its family, the black dogfish, typically measures long. It has a stocky, dark brown body that is darker below than above, and bears scattered, minute bioluminescent organs. Its two dorsal fins are preceded by stout spines, and the anal fin is absent. Active and schooling, the black dogfish is an opportunistic predator and scavenger that mainly consumes bony fishes, crustaceans, and cephalopods. It is aplacental viviparous, with females producing litters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etmopteridae
The Etmopteridae are a family of sharks in the order Squaliformes, commonly known as lantern sharks. Their name comes from the presence of light-producing photophore A photophore is a glandular organ that appears as luminous spots on various marine animals, including fish and cephalopods. The organ can be simple, or as complex as the human eye; equipped with lenses, shutters, color filters and reflectors, ...s on their bodies. The members of this family are small, under long, and are found in deep waters worldwide. The 45 species are placed in five genera. Three-quarters of the species are in the genus ''Etmopterus''.

Bramble Shark
The bramble shark (''Echinorhinus brucus'') is one of the two species of sharks in the family Echinorhinidae. Aside from the eastern Pacific Ocean, it is found in tropical and temperate waters worldwide. This rarely encountered shark swims close to the bottom of the seafloor, typically at depths of , though it may enter much shallower water. The bramble shark has a stout body with two small dorsal fins positioned far back and no anal fin. It can be readily identified by the large, thorn-like dermal denticles scattered over its body, some of which may be fused together. It is purplish brown or black in color and grows up to long. The diet of the bramble shark includes smaller sharks, bony fishes, and crabs, which this slow-moving species may capture via suction. It is aplacental viviparous, with females producing litters of 15–52 pups. Harmless to humans, it is an occasional bycatch of commercial and recreational fishers, and may be used for fishmeal and liver oil. Its p ...

Echinorhinidae
''Echinorhinus'' is the only extant genus in the family Echinorhinidae. Taxonomy Echinorhinidae are traditionally classified in the order Squaliformes, together with kitefin and gulper sharks.Compagno, 2005. "Sharks of the World". However, a phylogenetic estimate based on gene capture data and mitochondrial data suggests that they are not squaliform sharks, but may be more likely to be appropriately classed in their own group, as a sister group to angel sharks and sawsharks. Phylogenetic placement of Echinorhinidae has been ambiguous in morphological and molecular studies, either being included within Squaliformes, considered sister to Squaliformes, or placed in a separate group with Sawsharks (Pristiophoriformes) or angel sharks (Squatiniformes). For this reason they are sometimes given their own order, Echinorhiniformes. Etymology The name is from Greek ''echinos'' meaning "spiny" and ''rhinos'' meaning "nose".

Kitefin Shark
The kitefin shark or seal shark (''Dalatias licha'') is a species of squaliform shark in the family Dalatiidae, and the type species in its genus. It is found sporadically around the world, usually close to the sea floor at depths of . With a sizable oil-filled liver to maintain neutral buoyancy, this shark is able to cruise slowly through the water while expending little energy. The kitefin shark, the largest luminous vertebrate on record, has a slender body with a very short, blunt snout, large eyes, and thick lips. Its teeth are highly differentiated between the upper and lower jaws, with the upper teeth small and narrow and the lower teeth large, triangular, and serrated. Its typical length is , though examples as long as have been encountered. Armed with large teeth and a strong bite, the kitefin shark is a powerful, solitary predator that takes many different types of prey, ranging from bony fishes, sharks and rays, to cephalopods, crustaceans, polychaete worms, sipho ...

Dalatiidae
The Dalatiidae are the family of kitefin sharks of the order Squaliformes (the term "kitefin shark" also refers specifically to the species ''Dalatias licha''). Members of this family are small, under long, and are found worldwide. They have cigar-shaped bodies with narrow heads and rounded snouts. Several species have specialized bioluminescent organs. Though eight genera are in this family, four of them are monotypic.

Birdbeak Dogfish
The birdbeak dogfish (''Deania calcea'') is a dogfish shark of the family Centrophoridae found in the Pacific Ocean around Honshū, Japan, southern Australia, New Zealand, and Chile, and in the Atlantic Ocean from Iceland south to the Cape of Good Hope. The birdbeak dogfish has a very long, narrow snout, no anal fin, two long and low dorsal fins with grooved spines, small rectangular pectoral fins, and pitchfork-like denticles. It lives at depths between 73 and 1,450 m. It is ovoviviparous with up to 12 pups per litter. It eats bony fish and shrimp. In June 2018 the New Zealand Department of Conservation classified the birdbeak dogfish as "Not Threatened" under the New Zealand Threat Classification System. A study published in the Journal of the Marine Biological Association of the United Kingdom evaluated the reproductive strategy of the female deep-water shark birdbeak dogfish.

Leafscale Gulper Shark
The leafscale gulper shark (''Centrophorus squamosus'') is a dogfish of the family Centrophoridae. ''C. squamosus'' is reported to have a lifespan of approximately 70 years, based on otolith ring counts. It was the first described species in the genus Centrophorus, which now contains 13 species. Physical characteristics The leafscale gulper shark has no anal fin, two dorsal fins with spines, the first dorsal being relatively low and long, large eyes, and rough leaf-like denticles. Its maximum length is . Distribution Eastern Atlantic around continental slopes from Iceland south to the Cape of Good Hope, western Indian Ocean around Aldabra Islands, and western Pacific around Honshu, Japan, the Philippines, south-east Australia, and New Zealand. Habits and habitat The leafscale gulper shark lives near the bottom between , but usually below . Also occurs pelagically in much deeper water. It probably feeds on fish and cephalopods. It is ovoviviparous with a maximum of f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrophoridae
The Centrophoridae are a family of squaliform sharks. The family contains just two genera and about 15 species. They are sometimes called gulper sharks, but this is also the name of a specific species in the family, ''Centrophorus granulosus''. These are generally deepwater fish. While some, such as the gulper shark ''C. granulosus'', are found worldwide and fished commercially, others are uncommon and little-known. Their usual prey is other fish; some are known to feed on squid, octopus, and shrimp. Some species live on the bottom ( benthic), while others are pelagic. They are ovoviviparous, with the female retaining the egg-cases in her body until they hatch. They are small to medium sharks, ranging from in adult body length. The members of the genus '' Deania'' generally have a long flattened snout.

Squaliformes
The Squaliformes are an order (biology), order of sharks that includes about 126 species in seven families. Members of the order have two dorsal fins, which usually possess spines, they usually have a sharp head, no anal fin or nictitating membrane, and five to seven gill slits. In most other respects, however, they are quite variable in form and size. Most species of the squaliform order live in saltwater or brackish water. They are found worldwide, from northern to tropical waters, and from shallow coastal seas to the open ocean. All members of the family Eptomeridae and Dalatiidae and ''Zameus squamulosus'' possess photophores, luminous organs, and exhibit intrinsic bioluminescence. Bioluminescence evolved once in Squaliformes, approximately 111–153 million years ago, and helped the Squaliformes radiate and adapt to the deep sea. The common ancestor of Dalatiidae, Etmopteridae, Somniosidae, and Oxynotidae possessed a luminous organ and used bioluminescence for camouf ...
