mormyridae造句

• Gymnotiformes and Mormyridae have developed their electric organs and electrosensory systems ( ESSs ) through convergent evolution.
• The elephantfish ( " Mormyridae " ) are medium-sized freshwater fish abundant in the Nile.
• Mormyridae and their close relative Gymnarchus are also unique in being the only vertebrates where the male sperm cell doesn't have a flagellum.
• The largest members of the family Mormyridae, Cornish jacks attain a maximum known length of 1.5 m and a weight of 15 kg.
• The species of teleosts with electroreception ( Gymnotiformes, Mormyridae, and Silurids ) are freshwater fish and therefore have smaller ampullary canals than marine species.
• ""'Ivindomyrus opdenboschi " "'is a species of elephantfish in the family Mormyridae and the only member of its genus.
• ""'Isichthys henryi " "'is a species of freshwater elephantfish in the family Mormyridae and the only member of its genus.
• The Gymnarchidae ( the only species being " Gymnarchus niloticus ", the African knifefish ) and the Mormyridae are weakly electric fish able to sense their prey using electric fields.
• This may be because they did not spread into Africa before South America and Africa split, or it may be that they were out-competed by Mormyridae, which are similar in that they also use electrolocation.
• The aqua fauna in the delta as a whole, which is reflective of the lake also as it is integral to the delta, consists of 130 species mostly of the species in the families of Mormyridae, Mochokidae, and Cyprinidae.
• Each species of " Mormyrus " ( family : Mormyridae ) and " Gymnotus " ( family : Gymnotidae ) have evolved a completely unique waveform that allows the individual fish to identify between species, genders, individuals and even between mates with better fitness levels.
• The convergent evolution between the South American Gymnotiforms and the African Mormyridae is remarkable, with the electric organ being produced via the substitution of the same amino acid in the same voltage-gated sodium channel despite the two groups of fish being on different continents and the evolution of the electric sense organ being separated in time by around 60 million years.
