The shape and structure of these leads to the popular name "elephant-nosed fish" for those species with particularly prominent mouth extensions. The extensions to the mouthparts usually consist of a fleshy elongation attached to the lower jaw. They are flexible, and equipped with touch, and possibly taste, sensors.
Peters's elephant-nose fish (Gnathonemus petersii) is an African freshwater elephantfish in the genus Gnathonemus. Other names in English include elephantnose fish, long-nosed elephant fish, and Ubangi mormyrid, after the Ubangi River. The Latin name petersii is probably for the German naturalist Wilhelm Peters.
The subfamily Mormyrinae contains all but one of the genera of the African freshwater fish family Mormyridae in the order Osteoglossiformes.They are often called elephantfish due to a long protrusion below their mouths used to detect buried invertebrates that is suggestive of a tusk or trunk (some such as Marcusenius senegalensis gracilis are sometimes called trunkfish though this term is ...
Using this method, large numbers are caught quickly. Once caught, the fish are sold as whitefish or silver trumpeter fillets. The most common location of export is Australia. Under the IUCN, the three extant species of Callorhinchidae are all listed as least concern, as they remain common. While fishing quotas are in place in Australia and New ...
These fish have the ability to produce and analyze weak electric fields through a specialized organ, [40] (electric organ discharges), which Lissmann and coworkers first analyzed in 1958 through several experiments. [53] [54] Such electric fields provide these fish with a specialized sensory system for communication and orientation. [55]
A small species of fish that measures no more than half an inch in length is capable of producing sounds louder than an elephant, according to a new study. Tiny fish can make noises louder than an ...
Studies so far have shown the sequence and the gene order are more similar between human and elephant shark genomes than between human and teleost fish genomes (pufferfish and zebrafish), though humans are more closely related to teleost fishes than to the Australian ghostshark. The Elephant Shark Genome Project was launched with the aim to ...
A new study has uncovered a tiny fish species’s ability to produce a huge sound. Danionella cerebrum is 10 to 12 millimeters, or about 0.4 to about 0.5 inches, long and lives in shallow, murky ...
