Mormyrids are known for a few notable structural and physiological characteristics. They owe their apparent "stiffness" of body to their development, use of electrogenic sense. These fishes produce dipole moments, magnetic fields and can sense perturbations in the same. More

Mormyrids are distinguished by their snout which often is extended into a proboscis. The caudal peduncle serves as the site for a weak electrical organ used in orientation. More

Mormyrids are freshwater electric fish that have specialized electric organs in their tail for sending signals. They also carry specialized electroreceptors on their skin that are used for electrolocation and social communication. More

Mormyrids have a large brain-nearly equal in the body weight to brain weight ratio of humans. Most Mormyrids are nocturnal or crepuscular species. More

mormyrids for their learning abilities and the fact that many species engage in apparent "play" behavior consisting of batting around small objects, including air bubbles, with the head. More

The African mormyrids or elephant-nose fishes were noted for having unusually large brains already more than a century ago (Erdl, 1846). For a mean body mass of 26 g, the mean brain weight of Gnathonemus petersii reaches 0. More

Mormyrids have specialized electric organs for generating signals, and tuberous electroreceptors for receiving them. In electric communication, a variety of signals, varying in waveform and repetition rates can be generated for different social contexts. More

Mormyrids, also known as elephant trunk fish, have three electro sensory channels, each carrying specific types of information from electro receptors in the skin to the central brain area, for analysing and intergration. More

(particularly West African species), Mormyrids, Knifefish, Gouramis and larger rasboras and barbs. It tends to become slightly territorial as it matures, especially towards other Synos ... view full profile Synodontis petricola, cf. petricola 'dwarf'. More

Mormyrids also have relatively large brains, possessing the equivalent of a human brain in terms of relative size. More

small section about mormyrids which are rarely talked about in other books. The photographs are beautiful and very detailed. Previous poster may do well to actually take a look at the book instead of getting caught up in wording of other reviews. More

Mit diesem Organ sind Mormyrids in der Lage, mit einander zu verständigen, Opfer zu finden, und Fleischfresser zu ermitteln ist düsteres Wasser oder nachts. Mormyrids haben ein großes Gehirn-fast Gleichgestelltes inthe Körpergewicht zum Gehirngewichtverhältnis der Menschen. More

The lateral line of adult Mormyrids presents, in addition to the mechanoreceptors organs common to all the fish, three types of electroreceptors: the ampullary organ, the knollenorgan and the mormyromast (see Szabo 1965). More

All mormyrids are capable of generating weak electrical fields that they use for navigation; they hunt using the senses of touch and taste, the trunk-like barbel on the chin of the elephantnose functioning in the same way as the whiskers of a catfish. More
