Crenidens indicus. Day's karanteen 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 Indian Ocean.
Taxonomy
Crenidens indicus was first formally described in 1873 by the English zoologist Francis Day with its type locality given as the northern Indian Ocean. This taxon was previously treated as a subspecies of Crenidens crenidens{{Cof genus|genus=Crenidens|access-date=11 January 2024}} but was recognised as a valid species in 2013.{{cite journal | author1 = Yukio Iwatsuki | author2 = James Maclaine | year = 2013 | title = Validity of Crenidens macracanthus Günther 1874 (Pisces: Sparidae) from Chennai (Madras), India, with taxonomic statuses of the congeners (abstract) | journal = Ichthyological Research | volume = 60 | issue =3 | pages = 241–248| doi = 10.1007/s10228-013-0342-2 }} The genus Crenidens is placed in the family Sparidae within the order Spariformes by the 5th edition of Fishes of the World.{{cite book |author1=Nelson, J.S. |author1-link=Joseph S.

Description
Crenidens indicus has a dorsal fin which is supported by 11 spines and 11 soft rays while the anal fin contains3 spines and 10 soft rays. The shape of the body is a slightly compressed oblong oval which has a standard length which is 2.1 to 2.4 times its depth. The dorsal profile of the head is gently convex up to the origin of the dorsal fin but in adults it changes to concave behind the eyes and convex to the front of the eyes. The overall colour is silvery with greenish blue or olive-green tints. There are thin longitudinal stripes along the rows of scales. The fins are dull yellow and translucent. There is a dusky spot at the base of the pectoral fin.{{cite book |author=Yukio Iwatsuki |author2=Phillip C Heemstra |name-list-style=and |chapter=Family Sparidae |pages=284–315 |title=Coastal Fishes of the Western Indian Ocean |volume=3 |editor1=Phillip C Heemstra |editor2=Elaine Heemstra |editor3=David A Ebert |editor4=Wouter Holleman |editor5=John E Randall |year=2022 |isbn=978-1-990951-32-9 |publisher=South African Institute for Aquatic Biodiversity |url=https://saiab.ac.za/wp-content/uploads/2022/11/1._wiof_volume_3_text.pdf}} This species has a maximum published standard length of {{cvt|23.1|cm}}.{{FishBase|Crenidens|indicus|month=October|year=2023}}
