Type species : Squalus acanthias Linnaeus, 1758 by subsequent designation of Gill (1862: 405). Diagnosis . Squalus is characterized by the following combination of characters: slender and fusiform body, arched dorsally at anterior region; lateral keels restricted to caudal peduncle; short snout, rounded or obtuse at the tip; anterior nasal flaps lobe-like, however without forming nasal barbels; presence of slender dorsal spines without lateral grooves prior to each dorsal fin, extending or not to the apex of corresponding fin; second dorsal fin considerably smaller and more raked than first dorsal fin; caudal peduncle with conspicuous upper and lower precaudal pits; asymmetric caudal fin without subterminal notch; dorsal caudal lobe considerably greater in length than ventral caudal lobe; teeth unicuspid, small, similar in both jaws with short, slightly oblique cusps; dermal denticles unicuspid or tricuspid. Squalus is distinguished from Cirrhigaleus in having anterior nasal flaps with short secondary lobe without forming nasal barbels ( vs . secondary lobe very elongated and forming nasal barbels extending to anterior margin of mouth), second dorsal fin smaller and lower than first dorsal fin ( vs . dorsal fins of similar length and height with second dorsal fin as high and large as first dorsal fin), second dorsal-fin spine larger in length than first dorsal-fin spine ( vs . second dorsal-fin spine equal in length to first dorsal-fin spine), and conspicuous upper and lower precaudal pits ( vs . absence of lower precaudal pit). It is further differentiated from Cirrhigaleus by having narrow dermal denticles ( vs . denticles conspicuously broad), and body fusiform and somewhat arched dorsally throughout all of its length ( vs . body robust and markedly humped dorsally). : Published as part of De, Sarah T., De, Marcelo R. & Gomes, Ulisses L., 2016, Taxonomy and morphology of species of the genus Squalus Linnaeus, 1758 from the Southwestern Atlantic Ocean (Chondrichthyes: Squaliformes: Squalidae), pp. 1-89 in Zootaxa 4133 (1) on pages 7-8, DOI: 10.11646/zootaxa.4133.1.1, http://zenodo.org/record/400024 : {"references": ["Linnaeus, C.

Type species : Squalus acanthias Linnaeus, 1758 by subsequent designation of Gill (1862: 405). Diagnosis . Squalus is characterized by the following combination of characters: slender and fusiform body, arched dorsally at anterior region; lateral keels restricted to caudal peduncle; short snout, rounded or obtuse at the tip; anterior nasal flaps lobe-like, however without forming nasal barbels; presence of slender dorsal spines without lateral grooves prior to each dorsal fin, extending or not to the apex of corresponding fin; second dorsal fin considerably smaller and more raked than first dorsal fin; caudal peduncle with conspicuous upper and lower precaudal pits; asymmetric caudal fin without subterminal notch; dorsal caudal lobe considerably greater in length than ventral caudal lobe; teeth unicuspid, small, similar in both jaws with short, slightly oblique cusps; dermal denticles unicuspid or tricuspid. Squalus is distinguished from Cirrhigaleus in having anterior nasal flaps with short secondary lobe without forming nasal barbels ( vs . secondary lobe very elongated and forming nasal barbels extending to anterior margin of mouth), second dorsal fin smaller and lower than first dorsal fin ( vs . dorsal fins of similar length and height with second dorsal fin as high and large as first dorsal fin), second dorsal-fin spine larger in length than first dorsal-fin spine ( vs . second dorsal-fin spine equal in length to first dorsal-fin spine), and conspicuous upper and lower precaudal pits ( vs . absence of lower precaudal pit). It is further differentiated from Cirrhigaleus by having narrow dermal denticles ( vs . denticles conspicuously broad), and body fusiform and somewhat arched dorsally throughout all of its length ( vs . body robust and markedly humped dorsally). : Published as part of De, Sarah T., De, Marcelo R. & Gomes, Ulisses L., 2016, Taxonomy and morphology of species of the genus Squalus Linnaeus, 1758 from the Southwestern Atlantic Ocean (Chondrichthyes: Squaliformes: Squalidae), pp. 1-89 in Zootaxa 4133 (1) on pages 7-8, DOI: 10.11646/zootaxa.4133.1.1, http://zenodo.org/record/400024 : {"references": ["Linnaeus, C.
