Diagnostic Description

provided by Fishbase
Moderately convex dorsal head profile, short snout, terminal mouth and broad bands of contiguously set teeth. Distinguished from males of all species of Neochromis by having enlarged cephalic pores, and large scales on the lateral chest surface, gradually changing to small ones only at the level of the ventral fin insertions. Differs further from N. simotes by having a deeper body (38.4% SL vs. 34.0-35.7), a shorter (26.9% HL vs. 30.8-32.5) and narrower (31.7% HL vs. 35.4-37.7) snout, smaller preorbital depth (14.9% HL vs. 16.8-18.7); larger eyes (30.9% HL vs. 27.1-28.7), a shorter (30.1% HL vs. 30.8-33.1) and narrower (27.7-% HL vs. 32.8-34.4) lower jaw, subequally bicuspid crowns to the teeth in the outer rows, fewer inner tooth rows in both jaws (5), larger scales on the occiput, cycloid scales on the caudal part of the dorsum, larger scales on the chest, and the lack of small cycloid scales on the anal/genital region (Ref. 27668).

Haplochromis nigricans ( German )

provided by wikipedia DE

Haplochromis nigricans (Syn.: Neochromis nigricans) ist eine endemisch im ostafrikanischen Victoriasee vorkommende Fischart aus der Familie der Buntbarsche.

Merkmale

Haplochromis nigricans wird etwa zehn Zentimeter lang und ist relativ hochrückig. Die Körperhöhe liegt bei 34 bis 38,4 % der Standardlänge. Die Schnauze, bei Fischen die Region vom vorderen Augenrand bis zur Spitze des endständigen Mauls, ist relativ kurz, die Augen sind groß. Das Maul ist mit breiten Zahnbändern besetzt. Am Hinterkopf und auf der Brust sind die Schuppen größer als am restlichen Körper.

Männchen sind schwarz mit einem metallisch blauen Glanz. Die Schnauze, die Lippen, der Bereich zwischen den Augen, Wangen und Kiemendeckel sind blau. Die Afterflosse ist karmesinrot mit gelben Eiflecken. Die Schwanzflosse ist ebenfalls karmesinrot, die Bauchflossen sind schwarz. Weibchen sind olivfarben mit einem gold-gelben Schimmer auf den Kiemendeckeln und der Kehle. Rücken- und Afterflosse, sowie die Bauchflossen sind dunkel gelb, die Schwanzflosse ist graugrün. Auf den Körperseiten zeigen sie sieben bis acht ziemlich breite Querbänder.

Verglichen mit der nah verwandten Art Haplochromis simotes hat Haplochromis nigricans einen höheren Körper (38,4 % der Standardlänge vs. 34,0-35,7), eine kürzere (26,9 % der Kopflänge vs. 30,8-32,5) und schmalere Schnauze (31,7 % KL vs. 35,4-37,7), größere Augen (30,9 % KL vs. 27,1-28,7) und einen kürzeren (30,1 % KL vs. 30,8-33,1) und schmaleren (27,7-% KL vs. 32,8-34,4) Unterkiefer.

Lebensweise

Haplochromis nigricans ist bisher nur durch ein einziges Exemplar aus dem Norden des Sees bekannt, das am Nordufer des Victoriasees bei Entebbe gefangen wurde. Der britische Ichthyologe Greenwood untersuchte im Jahr 1956 den Mageninhalt eines Buntbarsches, den er als Haplochromis nigricans bestimmte, und fand vor allem Kieselalgen. Ob es sich bei dem untersuchten Exemplar tatsächlich um Haplochromis nigricans handelt ist aber nicht gesichert. Haplochromis nigricans lebt wahrscheinlich an felsigen Ufern des Victoriasee und ist wie alle Haplochromis-Arten ein Maulbrüter.
