Members of the leiognathid subfamily Gazzinae, comprising approximately two-thirds of ponyfish species, are sexually dimorphic with regard to features of the light organ system (LOS. [] Key Method We reconstruct the character evolution of both internal and external morphological features of the LOS to investigate the evolution of LO sexual dimorphism and morphology. Both internal and external sexual dimorphism in the ponyfish LOs were recovered as most likely to have evolved in the common ancestor of…
Anatomy and evolution of bioluminescent organs in the slimeheads (Teleostei: Trachichthyidae)
TLDR
The anatomy of the bioluminescent organs in trachichthyids is described and the evolution of this light‐producing system is placed in the context of a new phylogeny of the Trachichthyoidei to test the hypothesis that biol Luminescence evolved twice in the suborder and that the light‐ producing component derives from the perianal ectoderm.
Is sexual selection driving diversification of the bioluminescent ponyfishes (Teleostei: Leiognathidae)?
TLDR
The results suggest that if sexual selection is occurring in ponyfish evolution, it is likely acting only as a genetic isolating mechanism that has allowed ponyfishes to continuously diversify over time, with no overall impact on increases in diversification rate or morphological disparity.
Description of a new genus of ponyfishes (Teleostei: Leiognathidae), with a review of the current generic-level composition of the family.
TLDR
Photolateralis, new genus, is unique among ponyfishes in possessing a translucent mid-lateral flank stripe, which depending on the species, may be either a composite "stripe" comprised of numerous independent translucent windows, or a continuous translucent lateral stripe.
Morphology and evolution of bioluminescent organs in the glowbellies (Percomorpha: Acropomatidae) with comments on the taxonomy and phylogeny of Acropomatiformes
TLDR
The anatomy of the bioluminescent organs in Haneda's glowbelly and the Glowbelly is described and the familial taxonomy of the Acropomatidae was modified such that the previously described Malakichthyidae and Synagropidae were recognized.
Patterns of Phenotypic Variation in the Mouth Size of Lanternfishes (Teleostei: Myctophiformes)
TLDR
This study investigates the variation in mouth size of lanternfishes in an effort to better understand potential mechanisms of speciation in this group, as previous studies have indicated that there is considerable variation in the size and biodiversity of prey items of Lanternfishes.
Anatomical basis of diverse jaw protrusion directionality in ponyfishes (Family Leiognathidae)
TLDR
The anatomical basis of protrusion directionality was examined by measuring eight traits associated with the size and positioning of oral jaw bones by representing every major lineage within the ponyfish family.
Intra-species variations of Photopectoralis bindus (Family: Leiognathidae) collected from two geographical areas in East Java, Indonesia
Ponyfishes (Family: Leiognathidae) contributed ± 22% of all demersal catch in East Java, and also Indonesia. Photopectoralis bindus (Valenciennes, 1835), orangefin ponyfish, was the most dominant
Early Miocene Ponyfishes (Acanthuriformes, Leiognathidae) of the Carpathian Basin
The fossil record of ponyfishes (Leiognathidae) is documented by the presence of skeletal remains and otoliths in Europe, Africa and Asia. Here we describe in detail a set of skeletal imprints from
First record of ponyfishes (Perciformes: Leiognathidae) from the Oligocene of the Grube Unterfeld (“Frauenweiler”) clay pit
The first and presently only record of a ponyfish is described from the Lower Oligocene of the Grube Unterfeld (“Frauenweiler”) clay pit at Rauenberg (S Germany) and compared with other extant and
Description of a New Species of Ponyfish (Teleostei: Leiognathidae: Equulitini: Photolateralis) from the Gulf of Oman
TLDR
A new species belonging to the leiognathid genus Photolateralis, collected from the coastal waters of Oman, is described herein and is characterized by a lower jaw that is deep and convex in lateral view.

Evolution and diversification of a sexually dimorphic luminescent system in ponyfishes (Teleostei: Leiognathidae), including diagnoses for two new genera
TLDR
It is hypothesized that the species‐specific, sexually dimorphic internal and external modifications of the leiognathid LOS provide compelling evidence for an assortative mating scheme in which males use species‐ specific patterns of lateral luminescence signaling to attract mates, and that this system functions to maintain reproductive isolation in these turbid coastal environments.
A Clade of Non-Sexually Dimorphic Ponyfishes (Teleostei: Perciformes: Leiognathidae): Phylogeny, Taxonomy, and Description of a New Species
TLDR
It is shown that the evolution of the leiognathid LOS can be traced from a “simple” non-sexually dimorphic circumesophageal light organ to a complex and species-specific luminescence system involving not only major structural modifications of the light organ itself but also numerous associated tissues.
External and internal sexual dimorphism in leiognathid fishes: Morphological evidence for sex‐specific bioluminescent signaling
TLDR
A bioluminescent signaling function by males is suggested for the sexual dimorphism in leiognathids, which may play an important role in the schooling behavior as well as in species and sexual recognition of these coastal fishes.
Leiognathus elongatus (Perciformes: Leiognathidae): Two Distinct Species Based on Morphological and Light Organ Characters
TLDR
The use of the light-organ system is proposed in clarifying questions of leiognathid taxonomy by recognizing two species: L. stercorarius Evermann and Seale (group I), a previously buried synonym of L. elongatus (Glinther) (group II), which includes fishes previously named Equula elongata Giinther and L. popei (Whitley).
A New Species of Ponyfish (Teleostei: Leiognathidae: Photoplagios) from Madagascar, with a Phylogeny for Photoplagios and Comments on the Status of Equula lineolata Valenciennes
TLDR
A phylogeny for Photoplagios is provided based on the simultaneous analysis of anatomical features of the light-organ system and nucleotide characters and the taxonomic status of Equula lineolata Valenciennes is discussed, and the species is concluded to be a nomen dubium of uncertain placement beyond the family level.
Camouflage by Disruptive Illumination in Leiognathids, a Family of Shallow-Water, Bioluminescent Fishes
TLDR
The ventral illumination behavior of leiognathids, with their associated morphology, is compared and contrasted with the counterillumination systems that have been described in a number of mesopelagic fishes, shrimps and squids.

TLDR
A new species of Equulites is revealed using geometric morphometric techniques and is herein described, and the taxonomic status of Equula berbis Valenciennes is reviewed and is concluded to be a nomen dubium of uncertain placement beyond the family level.
ENDOSYMBIOTIC BIOLUMINESCENT BACTERIA FROM THE LIGHT ORGAN OF PONY FISH
TLDR
The isolated symbiotic bacteria were compared with free living bacteria isolated directly from sea water in the same area where the fish were collected, and it was possible to estimate the total number of viable bacteria within an organ, and to compare this with the weight of the organ.
