The fire eel (Mastacembelus erythrotaenia) is a relatively large species of spiny eel. This omnivorous freshwater fish is native to Southeast Asia but is also found in the aquarium trade. [ 1 ] [ 3 ] Although it has declined locally (especially in parts of Cambodia and Thailand) due to overfishing , it remains common overall.
Mastacembelus is a genus of many species of spiny eel fish from the family Mastacembelidae.They are native to Africa (c. 45 species) and Asia (c. 15 species). [4] Most are found in rivers and associated systems (even in rapids [5]), but there are also species in other freshwater habitats and a particularly rich radiation is found in the Lake Tanganyika basin with 15 species (14 endemic).
The Mastacembelidae are a family of fishes, known as the spiny eels. The Mastacembelids are part of the Order Synbranchiformes, the swamp eels, which are part of the Actinopterygii (ray-finned fishes). In an evaluation of the family in 2004, the subfamilies of Mastacembelidae were found to not be well supported and were rejected.
The European eel (Anguilla anguilla) is the one most familiar to Western scientists, beginning with Aristotle, who wrote the earliest known inquiry into the natural history of eels. He speculated that they were born of "earth worms", which he believed were formed of mud, growing from the "guts of wet soil" rather than through sexual reproduction.
Although its shape resembles an eel due to its slender and leg-less body, the monkeyface prickleback does not belong to the order Anguilliformes, which includes true eels, instead, it is classified under either the Perciformes, [1] along with nearly half of all bony fish, or the Scorpaeniformes, [2] according to different authorities.
Despite the name, the electric eel is a type of knifefish. The Gymnotiformes / dʒ ɪ m ˈ n ɒ t ɪ f ɔːr m iː z / are an order of teleost bony fishes commonly known as Neotropical knifefish or South American knifefish. They have long bodies and swim using undulations of their elongated anal fin.
Photos of the disaster, which will likely rank as the most destructive in L.A. history, capture the apocalyptic scale of destruction and heartbreak left in its wake.
The only food items actually found in the stomachs of snipe eels have been shrimp-like crustaceans, though ichthyologists believe they should be capable of catching and eating small fish and cephalopods also. Since predatory fish often feed on eel larvae, it is presumed by scientists and ichthyologists that they feed on snipe eel larvae as well.
