“…The overall lack of clear generic limits reinforces the findings of other studies that have found similar confusion within Muraenidae (Almada et al 2009;Reece et al 2010). Because of the extensive polyphyly observed in major genera, coupled with the placement of monotypic genera like Rhinomuraena and Strophidon and the type genus Muraena, the taxonomic status of most muraenine genera is in doubt.…”

“…Workers suspected that some large genera like Enchelycore and Gymnothorax did not represent natural groupings (e.g. Bö hlke et al 1989;Smith and Bö hlke 1997;Bö hlke and Randall 2000;Smith 2002;McCosker and Randall 2007) before recent studies demonstrated that they were not monophyletic (Almada et al 2009;Reece et al 2010). Therefore, it is not surprising that we found both genera to be polyphyletic.…”

“…Some of these studies have included muraenid representatives while investigating relationships among Anguilliformes and their relatives (e.g. Filleul and Lavoué 2001;Inoue et al 2003Inoue et al , 2004Inoue et al , 2010Obermiller and Pfeiler 2003;Wang et al 2003;Ló pez et al 2007;Johnson et al 2012), whereas others have examined the relationships within Muraenidae in more detail, confirming that several of the genera are not monophyletic (Jiménez et al 2007;Loh et al 2008;Almada et al 2009;Reece et al 2010). Of particular significance for muraenid taxonomy, Reece et al (2010) found Echidna, a genus composed exclusively of durophagous species, to be polyphyletic.…”

The family Muraenidae is one of the largest and most recognizable eel groups. Moray eels are key components of marine ecosystems but their relationships remain poorly understood. The phylogenetic relationships of the morays are examined herein using mitochondrial 12S and 16S sequence data, totaling 1673 bp for 139 taxa. The results of our analyses found support for a monophyletic family Muraenidae that is part of a monophyletic suborder Muraenoidei, which is revised to include the anguilliform families Heterenchelyidae and Myrocongridae, and to exclude the family Chlopsidae. The muraenids form two monophyletic subfamilies, Muraeninae and Uropterygiinae. Of the genera that had multiple species included for analysis, only the type genus of the family, Muraena, is found to be monophyletic. In the subfamily Uropterygiinae, Uropterygius is not recovered as a monophyletic genus. In the subfamily Muraeninae, the species-rich piscivorous genera, Enchelycore and Gymnothorax, and the durophagous genus, Echidna, are demonstrably not monophyletic. The monotypic Gymnomuraena is the sister group to all other muraenine species. The relationships within Muraenidae require much additional study and its genera remain in urgent need of revision. The order Anguilliformes is revised herein to include four suborders: Anguilloidei, Congroidei, Muraenoidei, and Synaphobranchoidei. All four families of the order Saccopharyngiformes are nested within Anguilliformes, recovered as part of a clade that includes Anguillidae; the saccopharyngiform families are referred to the suborder Anguilloidei sensu novum.

“…Groupers and moray eels are sedentary and high order carnivores (Almada et al, 2009;Ebner et al, 2016;Espino et al, 2018) which share preferences for prey when it comes to feeding (large crustaceans, fish and mollusks) (Brito et al, 2002;Condini et al, 2015;Espino et al, 2018;Machado et al, 2008). Groupers have also been reported to prey on moray eels (Linde et al, 2004).…”

While recent phylogenetic studies support the monophyly of the Muraenidae and the recognition of two distinct subfamilies (Muraeninae and Uropterygiinae), they do not support the subdivision of the family into the currently recognized genera (Jiménez et al, 2007;Loh et al, 2008;Almada et al, 2009;Reece et al, 2010;Santini et al, 2013;Tang & Fielitz 2013). In particular, Gymnothorax, the most speciose genus of the family (with c. 120 species), appears to be a non-monophyletic assemblage.…”

A comparative cytogenetic analysis, using both conventional staining techniques and fluorescence in situ hybridization, of six Indo-Pacific moray eels from three different genera (Gymnothorax fimbriatus, Gymnothorax flavimarginatus, Gymnothorax javanicus, Gymnothorax undulatus, Echidna nebulosa and Gymnomuraena zebra), was carried out to investigate the chromosomal differentiation in the family Muraenidae. Four species displayed a diploid chromosome number 2n = 42, which is common among the Muraenidae. Two other species, G. javanicus and G. flavimarginatus, were characterized by different chromosome numbers (2n = 40 and 2n = 36). For most species, a large amount of constitutive heterochromatin was detected in the chromosomes, with species-specific C-banding patterns that enabled pairing of the homologous chromosomes. In all species, the major ribosomal genes were localized in the guanine-cytosine-rich region of one chromosome pair, but in different chromosomal locations. The (TTAGGG)n telomeric sequences were mapped onto chromosomal ends in all muraenid species studied. The comparison of the results derived from this study with those available in the literature confirms a substantial conservation of the diploid chromosome number in the Muraenidae and supports the hypothesis that rearrangements have occurred that have diversified their karyotypes. Furthermore, the finding of two species with different diploid chromosome numbers suggests that additional chromosomal rearrangements, such as Robertsonian fusions, have occurred in the karyotype evolution of the Muraenidae.
