Here is a quote from the following link, "The female African lungfish lays its eggs in a nest in a weedy area of its habitat. Once the eggs hatch, the males guard the young for up to two months. The larvae have external gills that are reabsorbed during their metamorphosis into fully developed lungfish. As the African lungfish develops from juvenile to adult, its teeth fuse together to form tooth plates, which are used to chew its food."
One would be led to believe that it would not be unreasonable to assume that other lungfish lay eggs as well.
Protopterus annectensAfrican lungfish live in freshwater swamps, backwaters and small rivers in West and South Africa. These prehistoric animals have survived unchanged for nearly 400 million years and are sometimes referred to as "living fossils."
