An advanced embryo of Tomistoma schlegelii - estimated age between 60 and 65 days. This embryo comes from a nest on the Merang River in Sumatra. Very little is known about the nesting biology of this species, nor many of the factors involved in embryonic development. Like other crocodilians, temperature during incubation affects many factors such as pre- and post-hatching growth rate, together with sex.
