Xenocys jessiae, the black-striped salema, is a species of marine ray-finned fish, a grunt belonging to the family Haemulidae. It is endemic to the eastern Pacific Ocean.
Xenocys jessiae has a relatively slender, elongated body, notably different from most related species. [3] The head is conical in shape and has large eyes and a short diagonal mouth with a protruding lower jaw. It has very small teeth which are set in bands on the flaws and the palate. The dorsal fin is not continuous, the anterior spiny portion is completely divided from the posterior soft- rayed part. The dorsal fin contains 10 spines in the anterior portion and a single spine and 13-14 soft rays. The anal fin has 3 small spines and 10-11 soft rays. [4] This species attains a maximum total length of 30 cm (12 in). [5] The back is dark silvery-grey in colour, frequently showing yellowish green, yellowish blue or blue-green tints. The colour shades to paler silver on the flanks and to silvery-white on the underparts. [3] There are 7 black, horizontal stripes along the flanks. [4]
Xenocys jessiae is found in the eastern Pacific Ocean where it is endemic to the waters around the Galápagos Islands. [1]
Xenocys jessiae is found at depths between 0 and 20 m (0 and 66 ft). [1] It forms dense scoops in these shallow waters. [3] These spend the day along rock walls and over rocky slopes. [5] They feed on plankton and small fishes. [4] It is an oviparous species, spawning in distinct pairs. [5]
Xenocys jessiae was first formally described in 1890 by the American ichthyologists David Starr Jordan (1851-1931) and Charles Harvey Bollman (1868-1889) with the type locality given as Isla Santa Maria in the Galápagos Islands of Ecuador. [2] This species is placed in the genus Brachygenys by some authorities this was done when Haemulon was determined to be paraphyletic in molecular studies which showed Haemulon chrysargyreum , the type species of Felipe Poey’s Brachygenys, clustered with Xenistius californianus . The genus was therefore revived to include also includes the other species in Xenistius and this species. [6] [7] This change has been accepted by Catalog of Fishes [8] but not by Fishbase. [9] The specific name honours Jordan’s second wife Jessie Knight Jordan (1866-1952). [10]
Haemulidae is a family of fishes in the order Perciformes known commonly as grunts. It is made up of the two subfamilies Haemulinae (grunters) and Plectorhynchinae (sweetlips), which in turn contain about 133 species in 19 genera. These fish are found in tropical fresh, brackish, and salt waters around the world. They are bottom-feeding predators, and named for the ability of Haemulinae to produce sound by grinding their teeth. They also engage in mutualistic relationship with cleaner gobies of genus Elacatinus, allowing them to feed on ectoparasites on their bodies.

Plectorhinchus albovittatus, the two-striped sweetlips or giant sweetlips, is a species of marine ray-finned fish, a sweetlips belonging to the subfamily Plectorhinchinae, part of the grunt family Haemulidae. It is native to the Indian Ocean and the western Pacific Ocean.
The bluestriped grunt, also known as the boar grunt, golden grunt, humpback grunt, redmouth grunt, or yellow grunt, is a species of marine ray-finned fish, a grunt belonging to the family Haemulidae. It is found in the western Atlantic Ocean.

Haemulon is a genus of fish in the grunt family known as the scaled-fin grunts. Most are found in the western Atlantic Ocean, with a few species known from the eastern Pacific Ocean. This genus is considered to be one of the most important fish groups of the coral reefs of Brazil due to its commercial value and crucial ecological role.
Genyatremus luteus, the Torroto grunt, is a species of marine ray-finned fish, a sweetlips belonging to the subfamily Plectorhinchinae of the family Haemulidae. It is native to the Atlantic coast of South America from Colombia to Brazil.

Haemulinae is a subfamily of the Haemulidae and consists of the genera of that family which are regarded as being of New World origin, although they are now widespread. The subfamily is distinguished from the Plectorhynchinae by having a short dorsal fin which contains 13-16 soft rays, as opposed to the long dorsal fin with 17-26 soft rays of the subfamily Plectorhynchinae.
Brachygenys is a genus of marine ray-finned fish, grunts belonging to the family Haemulidae. The species within the genus are found in the eastern Pacific Ocean and western Atlantic Ocean. It is not yet recognised by Fishbase but is by the Catalog of Fishes.
Orthopristis reddingi, the bronze-striped grunt, is a species of ray-finned fish, a grunt belonging to the family Haemulidae. It is endemic to Mexico, occurring from central Baja California, including the southern Sea of Cortez, to central Mexico. It is found in schools over sandy substrates in coastal waters and the juveniles are frequently recorded in tidal pools. They are found at depths between 5 and 30 m. This species was first formally described in 1895 by the American ichthyologists David Starr Jordan and Robert Earl Richardson, the type locality was given as La Paz, Baja California Sur. The specific name honours in Benjamin B. Redding (1824-1882), the politician who was the first Fish Commissioner of California.
