It’s been a while since our last Herptile Spotlight. Kroten used to be the one writing this, but I am taking control for now because it’s a bit scientific now.
The reason why I suddenly want to write this is because there are so many people who seemed to confuse between these three emyduras: Emydura Sublogosa, Emydura Schultzei and Emydura Novaeguineae.
It’s actually easy to differentiate Emydura Sublogosa to the other two Emyduras, the one that is difficult to tell apart is between Emydura Schultzei and Emydura Novaeguineae. To be honest, I am still unsure which one is Papoe’s species; Schultzei or Novaeguineae.
According to this Journal :
These three Emyduras are spread on Papua and Australia but only Emydura Sublogosa can be found in Australia, the other two can only be found in Papua (hence Papoe’s name is Papoe -poe is read as poo). Emydura and Elseya is the same genus.
Animaldiversity.org stated the physical description of Emydura Sublogosa as following: Red-bellied short-necked turtles have olive-colored heads with a yellow-cream stripe running from the tip of the nose through the eye and into the iris (Georges et al. 2008). They have a prominent upper jaw and two yellow whiskers on the chin; the same yellow coloration runs along the light-colored jaw line. The upper neck region is dark gray and the lower, light gray with red streaks running along it. This same coloration appears on the bottom jaw and belly of the turtle, although the color can vary among bright orange, yellow, or pink (Legler and Georges, 1993; Ernst and Barbour, 1989). The limbs, tail, plastron, and abdominal regions are all marked with red (Ernst and Barbour, 1989). Young red-bellied short-necked turtles generally have brighter markings that fade as they grow, with their red color turning pinkish with time (Ernst and Barbour, 1989).
Please note that Emydura Sublogosa is NOT pink-belly short necked turtle, it is RED-belly short necked turtle.
The Reptiles of the Indo-australian Archipelago had given specific explanation of how to differentiate Emydura Schultzei and Emydura Novaeguineae. Reading the explanation, I sort of suspect (now) that papoe is NOT Emydura Schultzei, I think he is Emydura Novaeguineae.
Reading the last part: a yellowish streak on each side, becoming indistinct in adult specimens, from behind the eye to ….(and so on) makes me think that Papoe is Novaeguineae or White-belly short necked turtle.
BUT….Papoe’s plastron is pinkish.
Pictures by Andreas S. Hennig shows how white a Novaeguinea is:
And according to Hariprajitno’s Blog, here are pictures of a Schultzei:
Papoe is neither as white as Novaeguinea nor as pink as Schultzei…that’s why I am still in doubt. If anyone out there really know the different PLEASE tell me more about these two emyduras so that I can be convinced which one is Papoe; a Schultzei or a Novaeguineae. I know that it doesn’t matter which one is he I still love him either way but it’s nice to know more about his species.
