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.
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 ...
The Cape elephantfish eats sea urchins, bivalves, crustaceans, gastropods, worms, and bony fish. Its predators include seals and sharks. It is oviparous, laying two egg cases at a time. The egg case is large (about 25 cm) and spindle-shaped, with a ragged frill all around it.
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 ...
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 ...

As a benthic forager, the elephant fish rely heavily on these invertebrates, and any decline in the benthic population could have negative effects on its food security. This instability in food sources, combined with environmental stresses and fishing pressures, poses a serious threat to the long-term survival of the species.
