Diplodus cervinus, the zebra sea bream, is a species of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies. This species is found in the temperate north eastern Atlantic Ocean and the Mediterranean Sea.
Taxonomy
Diplodus cervinus was first formally described in 1838 as Charax cervinus with its type locality given as Madeira.{{cite journal |author=Lowe, R. T. |year=1838 |title=

Etymology
Diplodus cervinus has the specific name cervinus which means "deer" which comes from the Portuguese name for this species on Madeira, where Lowe collected the type, sargo veado which translates as "deer sea bream".{{cite web |url=https://etyfish.org/spariformes/ |title=Order SPARIFORMES: Families LETHRINIDAE, NEMIPTERIDAE and SPARIDAE |work=The ETYFish Project Fish Name Etymology Database |access-date=20 January 2024 |date=22 December 2023 |publisher=Christopher Scharpf |archive-date=30 October 2023 |archive-url=https://web.archive.org/web/20231030165034/https://etyfish.org/spariformes/ |url-status=dead }}
Description
Diplodus cervinushas an oval shaped body which is deep and compressed with a moderately sharp snout and a thick lipped slightly protrusible mouth. There are between 10 and 12 incisor-like teeth in the front of the upper jaw with 8 in the lower jaw. Behind these there are between 1 and 3, typically 2, rows of molar-like teeth. The dorsal fin is supported by 11 or 12 spines, increasing in height until the fourth spine, and between 11 and 14 soft rays. The anal fin has 3 spines and between 10 and 12 soft rays supporting it. The tail is forked.{{cite book |author=Kent E. Carpenter |author-link=Kent E.

The pelvic fins are dark with the other fins being greyish, becoming darker towards their margins.{{cite web |url=https://fishes-fnam.linnaeus.naturalis.nl/linnaeus_ng/app/views/species/taxon.php?id=109662&cat=271&epi=141|title=Diplodus cervinus |access-date=20 January 2024 |author=J-C Hureau |work=Fishes of the Northeastern Atlantic and Mediterranean |publisher=Naturalis Biodiversity Center}} The annular seabream has a maximum published total length of {{cvt|55|cm}}, although {{cvt|35|cm}} is more typical, and a maximum published weight of {{cvt|2.7|kg}}.
Distribution & habitat
Diplodus cervinus is found in the eastern AtlanticOcean from the Bay of Biscay to Mauretania, including the Canary Islands, Madeira and the Cape Verde Islands, into the Mediterranean Sea but not the Black Sea. This is a benthopelagic species, found at depths between {{cvt|30|and|80|m}} over rocky substrates but over sand substrates it can be found down to {{cvt|300|m}}.
Biology
Diplodus cervinus is an omnivorous fish which feeds on small invertebrates and seaweeds. The zebra seabream is a protogynous hermaphrodite, in which the males usually reach sexual maturity at a total length of around {{cvt|32.7|cm}} when they are five years old while the females attain sexual maturity at a total length of around {{cvt|27|cm}} and four years old. Spawning runs from spring to summer, with a peak in May and June. The young fish are recruited into the population in October up to January. These young fish occur at depths between {{cvt|0.5|and|8|m}}. The juveniles are found in schools in well vegetated rocky areas. Adults form schools of three to eight individuals in the spawning season, these consist of a single dominant male and a number of females.
Overfishing
Diplodus cervinus has many threats to its population. One of the threats is being overfished. The abundance has been reduced by 85% of the unexploited equilibrium level.{{cite journal |author=Pajuelo, J.G. |author2=Lorenzo, M.J. |author3=Dominguez-Seoane, R. |name-list-style=and |year=2003 |title=Age estimation and growth of the zebra seabream Diplodus cervinus cervinus (Lowe 1838) on the Canary Islands shelf (Central East Atlantic) |journal=Fisheries Research |volume=62 |issue=1 |pages=97–103|doi=10.1016/S0165-7836(02)00249-7 }}
