简单描述 型态特徵 | 形态测量图

背棘 (总数): 16 - 17; 背的软条 (总数): 10-11; 臀棘 3; 臀鳍软条: 8 - 10. Diagnosis: A heavily-built large tilapia species with a wide rounded head; dwarf populations exist in some crater lakes, showing bony 'hunger-form' body shape (Ref. 118638). Females and juveniles with grey bodies and 6 or more vertical bars; males have a bright blue, occasionally white or green, 'mask' across the head; when fully ripe, the underside of most of the body can be black, with the upper surface a conspicuous white to pale blue; genital tassel can be long and branched, pinkish to bright yellow; females and non-territorial males are indistinguishable from Oreochromis karongae (Ref. 118638).
低的咽有齿的区域有凹的侧边; 硬骨 1.26-1.36 的平均长度倍于它的宽度与 37.6-40.6个头长; 叶片 1.6-2.4 倍于有齿区域的平均长度。 尾鳍有鳞的。

生物学特性     字汇 (例如 epibenthic)

A semi-pelagic species (Ref. 4967), found in all kinds of habitats but seen mostly in shallow water; it is abundant in the southeastern arm of Lake Malawi, where it occurs in shallow, vegetated bays (Ref. 5595). It feeds on phytoplankton and sometimes from the sediment on the sand; diatoms constitute the major part of its diet (Ref. 5595). Major component of the fisheries catch in Lake Malawi (Ref. 118638). IUCN conservation status is endangered, due to declining population trend (Ref. 118638).

生存在一个 21.5-29 °C(参考文献 2) 的温差, 在各种的栖息地但是被见到主要在浅水区。 在水浅的长满植物的海湾中很丰富。 形成鱼群。 吃浮游植物, 主要地硅藻, 与有时在沙子上的从沉淀物.(参考文献 5595)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

Mating behavior includes the T-stand, both partners alternately forming the horizontal part of the T. Eggs are laid in batches and immediately picked up by the female. Fertilization takes place both on the ground and in the mouth. Females brood eggs/young, guarding their fry until about 15 mm (Ref. 2781). 非洲: 馬拉威湖的特有種。
