===Developmental Stages=== [[File:Ke - Conraua goliath - 1.jpg|thumb|alt=Conraua goliath|Specimen at the [[Cambridge University Museum of Zoology]]]] While the reproductive behavior for this species is mostly not well-known, studies by Lamotte, Perret, and Zahl have allowed an overall chronological table of larval development to be created.<ref name="sabater1985" /> Typically after 24 hours, the cover of the egg mass becomes yellow and the eggs become dark gray-brown. These egg masses were found attached to the bottom of plants. <ref name="sabater1985" /> First Month: no organs were differentiated and only the ocular region showed significant pigmentation and transparent external gills. The lengths were {{Cvt|8-10|mm}} and while the body/tail appeared to be slightly pigmented, the abdomen was always nearly white.<ref name="sabater1985" /> Second Month: The activity of the tadpoles increased greatly for they are now beginning to feed on leaves. Furthermore, they have developed a denser pigmentation, and the spiraculum and anal tube are now beginning to become visible. Additionally, the mouth and the eyes are beginning to function. Sizes range {{Cvt|19-21|mm}}. As the month continues, pigmentation is becoming more intense via the presence of nearly black spots, two rows of teeth are developing on both the upper and lower lip, feeding increases greatly, and their size becomes {{Cvt|24|mm}}.<ref name="sabater1985" /> Third Month: The posterior legs are now beginning to form and the length of the tadpoles are around 40mm. As the month progresses, the posterior legs become larger and joints/fingers are becoming more distinguishable. The total length of the tadpoles is now 45 mm. Finally, at the end of the month, anterior legs have fully appeared, posterior legs are grown with long and powerful fingers accompanying this growth, the mouth has become an arched slot line, tail regression has begun, and these tadpoles begin to put their head out of the water in order to breathe.<ref name="sabater1985" /> Fourth Month: All of the specimens in the experiment reached the final stage of metamorphosis. The tail has been either completely or nearly reabsorbed, the shape and color of adults is obtained with slightly lighter and greener pigmentation, the total length is {{Cvt|35|mm}}. The large size characteristic of these frogs is not obtained yet. The entire process of larval development takes approximately 85β95 days to complete. <ref name="sabater1985" />
