Channa melanoptera

  • We are currently upgrading MFK. thanks! -neo
How's you German??


According to Snakeheads.org the people who know it is a separate species, but I am not sure that that is one in the first picture.Take a look below.


Quote"Bleeker's drawing of the head shields of c. melanoptera, taken from his famous ichthyological atlas. Drawings of head shields were meant for species identification. Bloch 1793 started with this method and this method is still used"



Any translations????;)


I will add i have never seen one in the scales as it were.


from Snakeheads.org"Ophiceph. corpore elongato antice cylindraceo latiore quam alto postice compresso, altitudine 7 circiter in ejus longitudine; capite acuto 5 in longitudine corporis, depresso, genis convexo; altitudine capitis 2 et paulo, latitudine 1 1/2 ad 1 3/5 in ejus longitudine; linea rostro-dorsali rostro convexa, fronte et vertice declivi concaviuscula; oculis diametro 7 circiter in longitudine capitis, diametris 2 et paulo distantibus; maxilla superiore maxilla inferiore vix breviore, longe post oculum desinente, 2 2/5 circiter in longitudine capitis, dentibus multiseriatis intermaxillaribus, vomerinis palatinisque 0omnibus parvis serie interna ex parte dentibus ceteris paulo longioribus, inframaxillaribus parvis internis lateralibus conicis aliquot caninoides; squamis cijeloideis parte libera granulatis, capitis parte postoperculari 8 vel 9, lateribus 55 p. m. in serie longitudinali; linea laterali antice et postice recta sub radio dorsali 12° circiter valde deflexa; singulis squamis tubulo simplice notata; pinna dorsali postice obtusiuscule rotundata, pectoralibus obtusis rotundatis flexuram linea laterali fere attingentibus 6 3/5 circiter, ventralibus acute rotundatis 12 3/5 circiter, caudali 5 1/2 circiter in longitudine corporis; anali postice acute rotundata dorsali paulo humiliore; colore corpore superne violascente-olivaveo inferne aurantiaco-roseo pinnis ventralibus dilute violaceis; dorsali dimidio posteriore at anali tota vittis obliquis transversis ex parte abruptis pulchre coeruleis. caudali membrana dimidio basali maculis coeruleis in series irregulares transversas dispositis."

oops got it the wrong way round. Stotty i dont think that german. Coz i can read some german. and i can't read any of that
 
From what I've noticed, C.marulioides body and head are somewhat longer & slender than this other species... C. melanoptera body looks more broader wider than marulioides, but doesn't grow quite as large in length. Also, melanoptera's head looks somewhat rounder, fatter, and shorter lengthwise, compared to marulioides. Melanoptera's head also looks somewhat 'flatter' than marulioides... the eyes appear to look like their 'sitting up on top of the head" more, rather than side to side on the head/face, like maruliodes or other species. Also, the gap space between melanoptera's eyes are set much further apart from each other, compared to the eye placement of C. marulioides.

Another distinctive trait between the two is the dorsal fins. C. maruliides has a white spotting/speckling "snowflake' like pattern across it, where C. melanoptera's dorsal fin lacks this. I have noticed some 'very little' spotting on some melanoptera, but only on mature specimans.

Common name for Channa melanoptera is "Black-finned" snakehead.

Common name for Channa marulioides is "Emperor" snakehead.


Now please be aware that this info/data is just from what i've learned and researched over a period of time. In no means am I an 'expert' on this subject. Nor do or have I, ever even kept or owned these species. This is all based on literature & photos that I've seen and read in either books or the internet. :)

Blackfinned Snakehead! now I remember, yes yes it almost looks like Emperor Snakehead / Channa Marulioides. But both seem to grow about the same length, about 65cm. They both look about the same and can only be differed through colouration, Channa Marulioides possesses an ocellated spot on the upper part of the caudal fin base, similar to Channa Marulius / Cobra Snakehead, but the Blackfinned Snakehead / Channa Melanopterus lacks this ocellus. Besides Channa Marulioides also often ( but not always ) possessing the several patches of dark scales rimmed by white margins along the sides of the body.
