Gymnothorax baranesi, a new moray eel (Anguilliformes: Muraenidae) from the Red Sea
Gymnothorax baranesi n. sp. is described from three specimens collected in moderately deep water in the Gulf of Aquaba, Red Sea, Israel. It is characterized by irregular, pale, rosette-like spots on a dark background. The snout is somewhat slender. The intermaxillary teeth are arranged in one peripheral and one median row. The maxillary teeth are arranged in 1–2 rows, the inner row, when presen...
متن کاملChromosomes of Gymnothorax funebris and the karyotypical differentiation within Gymnothorax (Anguilliformes: Muraenidae).
Cytogenetic studies in Gymnothorax funebris revealed a diploid chromosome number 2n = 42 (6 metacentrics, 4 submetacentrics, and 32 acrocentrics, FN = 52). The results obtained are novel and similar to those previously described for species belonging to Muraenidae family. The conventional karyotype is also novel and divergent from other species of the genus Gymnothorax, where a higher proportio...
متن کاملA new species of Short Brown Unpatterned Moray Eel of the Genus Gymnothorax (Anguilliformes: Muraenidae) from the Bay of Bengal.
A new species of short brown unpatterned moray eel of the genus Gymnothorax, Gymnothorax mishrai sp. nov. is described from a specimen of 324 mm total length, collected from the Bay of Bengal. The species is distinguished by having the dorsal-fin origin before gill opening, jaw pores with brown rim, two branchial pores, total vertebrae 134 (MVF: 9-59-134), three median intermaxillary teeth, uni...
متن کاملGymnothorax eurygnathos, a new moray from the Gulf of California (Anguilliformes: Muraenidae).
A new species of moray eel from deep water in the Gulf of California is described. It is dark brownish-black with an overall pattern of pale irregular blotches; a short, broad head; wide, triangular jaws; deeply serrate and partially biserial teeth; dorsal-fin origin above and behind gill opening; and 10 predorsal, 66 preanal, and 134 total vertebrae. This combination of characters is not share...
متن کاملIdentification of two new repetitive elements and chromosomal mapping of repetitive DNA sequences in the fish Gymnothorax unicolor (Anguilliformes: Muraenidae)
Muraenidae is a species-rich family, with relationships among genera and species and taxonomy that have not been completely clarified. Few cytogenetic studies have been conducted on this family, and all of them showed the same diploid chromosome number (2n=42) but with conspicuous karyotypic variation among species. The Mediterranean moray eel Gymnothorax unicolor was previously cytogenetically...
