| The order Anguilliformes comprises 15 families, 141 genera and 791 fish species. Eight families had at least one karyotyped species, with a prevalence of 2n = 38 chromosomes and high fundamental numbers (FN). The only exception to this pattern is the family Muraenidae, in which the eight species analyzed presented 2n = 42 chromosomes. Despite of the large number of Anguilliformes species, karyotypic reports are available for only a few representatives. In the present work, a species of Ophichthidae, Myrichthys ocellatus (2n = 38; 8m+14sm+10st+6a; FN = 70) and four species of Muraenidae, Enchelycore nigricans (2n = 42; 6m+8sm+12st+16a; FN = 68), Gymnothorax miliaris (2n = 42; 14m+18sm+10st; FN = 84), G. vicinus (2n = 42; 8m+6sm+28a; FN = 56) and Muraena... |

| Two specimens, 565 and 715 mm total length (TL), of the dusky snake eel, Ophichthus cylindroideus, collected southwest of Santa Marta, Colombian Caribbean, were examined. This species was not reported by Acero and Garzón-Ferreira (1995), then it is was not listed in the Colombian marine fishes data bases. However, McCosker et al. (1989) did examine one specimen (USNM 94755, 622 mm TL) from Puerto Colombia. External morphological and morphometric data are compared, as well as some osteology features. |
