• It is a small nektonic opportunistic carnivore in the family Osteoglossiformes which includes other bony-tongues such as the extant species of Arowana and Arapaima.
• "' Osteoglossiformes "'( Greek : " bony tongues " ) is a relatively primitive order of ray-finned fish that contains two sub-orders, the Osteoglossoidei and the Notopteroidei.
• "' Osteoglossoidei "'are a suborder of the order Osteoglossiformes ( Latin : " bony tongues " ) that contains the butterflyfish, the arowanas and bonytongues, as well as extinct families.
• Some sources place them in their own Order-"'Hiodontiformes "'( as in the treatment here ), while others retain them in the order "'Osteoglossiformes " '.
• The final tract of the rectum still holds faeces in which a piece of skin is visible showing seventeen scales of a fish of the Osteoglossiformes that was nine seasons old, judging from the growth lines on the scales.
• "' Notopteroidei "'is a suborder of the order Osteoglossiformes that contains the Gymnarchidae ( aba ), Notopteridae ( feather backs and knifefish ), mormyrids ( the elephantfishes ), as well as extinct families.
• These are traditionally classified with the Osteoglossiformes, and many authorities still do, but fossil study of the extinct " Yanbiania " suggest that the hiodontids separated from other osteoglossiforms early, and thus belong to a separate order.
