Nebris és un gènere de peixos de la família dels esciènids i de l'ordre dels perciformes.[2]
Nebris ist eine Gattung aus der Familie der Umberfische (Sciaenidae). Sie umfasst zwei Arten, die im West-Atlantik und im tropischen Ost-Pazifik vorkommen.
Die Fische der Gattung sind länglich mit spitz zulaufendem Hinterende und breitem, abgerundetem Kopf. Dieser weist einen schwammartig porösen Schädel auf. Die Schuppen sind klein und glatt. Das Maul ist endständig und groß mit hängenden Winkeln und vorstehendem Unterkiefer. Das Kinn weist keine Barteln auf. Die Augen sind sehr klein. Die Rückenflosse ist durch eine deutliche Kerbe geteilt und weist ebenso wie die Afterflosse Schuppen auf. Die Schwanzflosse ist am Ende zugespitzt.

Nebris is a small genus of marine ray-finned fishes belonging to the family Sciaenidae, the drums and croakers. There are two species in the genus, one in the Western Atlantic Ocean and one in the Eastern Pacific Ocean.
Nebris was first proposed as a monospecific genus in 1830 by the French zoologist Georges Cuvier when he described Nbris microps[1] from Surinam.[2] This genus, along with Larimus, has been placed in the subfamily Lariminae by some workers,[3] but the 5th edition of Fishes of the World does not recognise subfamilies within the Sciaenidae, which it places in the order Acanthuriformes.[4]
Nebris is Greek and means the hide of a fawn, an allusion Cuvier did not explain, describing N. mictops as solver in lfe and uniformly grey-brown when preserved in alcohol.[5]
There are currently two recognized species in this genus:[6]
Nebris croakers have elongate bodies which taper towards the caudal fin with a rounded head, the top of which is compressible, with small eyes. The edge of the preoperculum is smooth. The large, upwards pointing mouth opens to the front and there are no barbels on the chin, although there are 4 tiny pores. The dorsal fin has a large incision[7] and is supported by between 8 and 11 spines and 29 and 32 soft rays. The anal fin is supported by 2 spines and 9 or 10 soft rays.[8] They are covered in small cycloid scales including the dorsal and anal fins.[7] N. microps has a maximum published total length of 40 cm (16 in) while for N. occidentalis it is 60 cm (24 in).[6]
Nebris croakers are found in the western Atlantic and eastern Pacific Oceans. M. micropsoccurs from Colombia to southeastern Braxil in costal waters and estuaries on sand over mud substrates.[8] M. occidentalis occurs from Guatemala to Peru in the surf zone and in estuaries and coastal lagoons.[9]
Nebris croakers are important quarry species for fisheries and are regarded as palatable food fish. They have wide distributions and are both classifies as Least Concern by the IUCN.[10][11]

Nebris Cuvier, 1830 è un genere di pesci ossei appartenenti alla famiglia Sciaenidae.
Il nome scientifico del genere deriva dalla parola greca nebris, che indicava la pelle del cerbiatto.
Entrambe le specie presentano un corpo allungato, piuttosto compresso ai fianchi, con profilo dorsale e ventrale poco arcuati, pinne arrotondate, pinna dorsale bassa e lunga. La livrea sebbene diversa, presenta un dorso più scuro, macchiato e marezzato di bruno, e un ventre e fianchi bianco argentei. La lunghezza massima si attesta sui 40 cm per Nebris microps e sui 60 cm per N. occidentalis.
Il genere comprende due specie:
