鱼通常不吃，而育雏在他们的嘴里。在两种石生食藻动物Tropheus duboisiandT.在坦噶尼喀湖，口孵雌鱼表现出摄食行为。在杜布氏胸水鳖中，无论其后代的发育状况如何，口孵雌鳖的摄食率均为雄鳖和非口孵雌鳖的80%。在摩尔氏蚁中，孵卵早期胚胎的雌性很少取食，但其取食率随着后代的发育而增加。对标本的研究表明，在前一种物种中，这些雌性动物是为了自己和幼崽的营养而进食，而在后一种物种中，这些雌性动物只是为了幼崽的营养而进食。
Fishes usually do not eat while brooding offspring in their mouths. In two epilithic algal eatersTropheus duboisiandT. mooriiin Lake Tanganyika, however, mouthbrooding females exhibited feeding actions. InT. duboisi, the feeding rate of mouthbrooding females was 80 percent of that of males and non brooding females irrespective of the developmental state of their offspring. InT. moori, females brooding early embryos rarely fed but their feeding rate increased with development of offspring. An examination of specimens revealed that such females took food for nourishment of themselves and the young in the former species but for nourishment of only the young in the latter.
