The anterior neurals are typically longer, than the posterior ones, but the great width of the bones is, mahogany brown with a cream or yellow rim. Although Malayemys are extensively traded and used for religious release, only few studied turtles appear to be translocated by humans. Incubation periods and rates of hatching have been studied, However, the reported incubation lengths and hatch rates may, not be representative of natural nests due to the passage of, indeterminate lengths of time between nesting and collection, and the effects of controlled incubation conditions. It lives in the Mekong River Basin of northeastern Thailand, and in nearby Vientiane in Laos.

He talks about how in the wild, research shows that these turtles feed primarily on snails. It is among the most poorly known turtle species because of research taxonomic biases and this species' relatively recent recognition as a unique taxon. The Last Glacial Maximum (LGM) projection of the predictive SDMs suggests two distinct glacial distribution ranges, implying that the divergence of M. macrocephala and M. subtrijuga occurred in allopatry and was triggered by Pleistocene climate fluctuations. affect reproduction and development in turtles (Kitana et al. lanterns in Bangkok (Thirakhupt and van Dijk, pers.
