摘要: Summary Large African barbs (genus Labeobarbus) of Lake Tana (Ethiopia) form a species flock, which includes 15 differing in biology, ecology, and shape features, including skull proportions. Early craniogenesis was studied three barbs: L. intermedius, proposed ancestor brevicephalus, small-sized early-maturating barb, megastoma, large-sized, piscivorous species. The general sequence cranial cartilage bone appearance is the same for barb studied. However, they differ greatly temporal pattern craniogenesis. As compared to bony development accelerated relative chondrocranial brevicephalus retarded megastoma. These differences are account different proportions displayed by these barbs.
