Wiki info

The eggs and young are similar to those of frogs, but the offspring differ from both frogs and other lungfishes by the absence of external gills during early development. Within the egg, head structures and pigmentation start to appear by day 17. They hatch after three to four weeks and resemble tadpoles. The young fish are slow-growing, reportedly reaching 27 mm (1. 1 in) after 110 days, and about 60 mm (2. 4 in)after 8 months. During the first week, it lies on its side, hiding in the weeds, and moving only when stimulated by touch. It will swim spontaneously, and often retreat back into the gelatinous envelope when disturbed. Newly hatched larvae develop a ciliary current over their skin and gill surfaces. This is believed to either provide respiratory exchange across the skin and gills without necessitating any movements of the jaw or brachial apparatus, or to keep the skin of the unprotected larvae free of debris, parasites, and predatory protozoans. Larvae are reported not to feed for two to three weeks while the yolk is still present. By the time the yolk is fully used, a spiral valve has developed in the intestine and the fish starts to feed. The young can grow about 2 inches per month under optimal conditions.
