Ontogenetic development of the gastrointestinal tract of African lungfish larvae Protopterus aethiopicus (Heckel 1851) : a light microscopy study
The organogenesis of the digestive system was described in the African lungfish (Protopterus aethiopicus) from 6 days post-hatching (6 DPH) to 17 days post-hatching (17 DPH) reared at 27 degrees C. To elucidate the position of the gastrointestinal tract in relation to the neural tube, notochord and...

Microscopical observation showed that yolk reserves were not completely depleted by 17 DPH. During the endogenous feeding period at least up to 17 DPH, the larval digestive system experienced a fast transformation with almost complete development of most digestive organs (pharyngeal teeth, intestinal vestibule, intestine and liver).
