gymnotiforms造句

• In most gymnotiforms, the electric organs are derived from muscle cells.
• In gymnotiforms, the electric organ discharge may be continuous or pulsed.
• Male gymnotiforms emit these accelerated signals during aggression and courtship.
• They are mostly found on weakly electric fishes such as gymnotiforms and mormyrids.
• Gymnotiforms have two classes of electroreceptive organs, the ampullary receptors and the tuberous receptors.
• With the denotation of " knifefish ", the Notopterids should not be confused with Gymnotiforms, the electric knifefishes from South and Central America.
• To classify types of electroreceptors, the first differentiation point should be made between ampullary and tuberous organs, which exist in both mormyrids and gymnotiforms.
• Apternotids, a member of the wave-type gymnotiforms, is different from all other electric fishes as being the only family possessing neurogenic electrocytes.
• Therefore, to make effective communication, it is necessary for the electric fishes to narrow the broad frequency spectrum of the larval EOD . Secondly, it is known that the electroreceptors of catfish, gymnotiforms, and most pre-teleost fish are tuned to lower frequencies.
• 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.
