Mormyridae are well known and intensively studied for their weak electric organ discharges, which facilitate communication and orientation. The Gemminger bones of Mormyridae are located next to the electrical organ in the caudal peduncle; however, they have not attracted much interest until recently. Therefore, we investigated the diversity of Gemminger bones in mormyrids and studied their ontogenetic development in Mormyrus rume proboscirostris. Gemminger bones are paired, thin, elongated ossifications lying on the dorsal and ventral sides of the caudal peduncle, and usually reach anterior well below the dorsal and anal fin bases. Ontogeny revealed that they are not intermuscular ossifications, as suspected based on the anatomical position of this structure and the systematic position of the mormyrids. Instead, they are membrane ossifications that originate from the fin stays of the dorsal and anal fins.

We present the complete genome sequences of 38 species of elephantfishes from 20 genera. Illumina sequencing was performed on genetic material from single wild-caught individuals. The reads were assembled using a de novo method followed by a finishing step. The raw and assembled data is publicly available via Genbank.

The genus Mormyrus Linnaeus, 1758 has been well studied in western Africa where five species are currently recognized. Mormyrus subundulatus Roberts, 1989 was described in 1989, and, although morphologically and genetically close to Mormyrus rume Valenciennes, 1847, is still considered by the most recent studies as a distinct species. It is endemic to the Côte d\’Ivoire and Ghana River systems. It was historically recorded from only three locations but is today very likely extirpated from one of them and threatened in the remaining two. It is categorized as \“Vulnerable B1ab(iii)\” by the IUCN Red List (Dankwa 2020). Although a few papers describe precisely the morphology and electric signal of the species, they are based on a very limited number of samples. In this paper, we present new data on the morphological characteristics of the species (extending the dorsal fin rays count range, which is the main morphometric criterium to distinguish M. subundulatus and M. rume) based on Museum samples and samples collected recently a few kilometers away from the type locality. Determination of the newly collected material was confirmed by the analysis of a frag- ment of the Cytochrome b gene, and we produced the first sequence fragment of the cytochrome oxydase subunit 1 (COI) for this species.

The present study sheds light on the growth pattern of the elephant snout fish (Mormyrus kannume, Mormyridae) in the Damietta branch of the Nile during the period from January to December 2010. This is done through studying the biometric characters, length\–weight relationship, condition factors, growth performance index as well as the natural mortality. The linear regression for 15 morphometric characters in total length and 4 morphometric characters in head length was applied. The higher coefficient of the characters\’ determinations which fit best was also applied. Five meristic characters were determined (dorsal fin rays, 49\–69; pectoral fin rays, 12\–15; ventral fin rays, 6; anal fin rays, 17\–21 and vertebrae, 49\–52). Fish length varied between 14.0 cm and 43.0 cm TL with a modal length range from 19 to 22 cm representing 61.36\% of the fish sample. A length\–weight relationship using the total weight was found to be Log W = \−2.2218 + 3.063 Log L (R2 = 0.997) and using the gutted weight was Log W = \−2.1549 + 3.003 Log L (R2 = 0.995) hence exhibiting isometric growth. The average condition factors for different lengths were 0.76 \± 0.06. The chi-square of the overall sex ratio (male:female = 1:0.42) was significant at P \< 0.01. The life span of this species is five years, with individuals of two years of age dominating the population. The different growth parameters were estimated at (K = 0.141, to = \−0.271, L\∞ = 80.65 cm, W\∞ = 4151 g, ФL = 2.96 and ФW = 1.56). The natural mortality was 0.34, the M/K ratio was 2.38 and the variation of M by age model was also computed.

Field studies on the electric organ discharges (EODs) of Mormyrus species are rare, likely due to their biology hindering live capture in large numbers. Here the EODs of four Nilo-Sahelo-Sudanic species, Mormyrus caschive Linnaeus, 1758, M. kannume Forssk\ål, 1775, M. hasselquistii Valenciennes, 1847 and M. rume Valenciennes,1847, are compared and discussed. Their discharges are largely equal to each other, mainly showing differences in length and peak of Fourier transformation with less pronounced differences in the relative amplitude of phases within an EOD. The discharge properties allow species discrimination, at least within eco-regions, and thus likely play a role in species recognition.
