McCord's snakeneck turtle is found exclusively on the tiny island of Rote in Indonesia. It has an extremely limited distribution, with just two known populations on the island, existing on a patch of 70 square kilometers. (Kuchling, et al., 2013; Rhodin, et al., 2010; Rhodin, 1994; Rhodin, 1995; Rhodin, et al., 2008)
Incubation takes four months resulting in hatchlings that average 25.5 mm in carapace length. One observation of a wild juvenile indicates that (Avise and Pearse, 2001; Jarrett, 2011; Rhodin, et al., 2008)developed three growth rings (annuli) per scute. Such annuli are not found in adults due to weathering making which makes the annuli inaccurate for aging in older turltes
Mating practices for McCord's snakeneck turtle appear to resemble other more common snake-necked turtles. Males pursue their mates from behind. Mating occurs in water, and courtship culminates when the male is able to grasp the carapace of his partner with its claws from behind. The mating system is assumed to be polygnandrous which is common in the family Chelidae. (Avise and Pearse, 2001; Jarrett, 2011; Rhodin, et al., 2010)
The lifespan of (Kennet, et al., 2009)remains relatively unknown, as the documentation of an entire lifespan has not been completed. However, other snake-necked turtles have a lifespan of 30 to 40 years.
The skull and jaw of snake-necked turtles, and this is believed to indicate that this species is a generalist carnivore or piscivore. Insects, small fish and tadpoles are reported to be of importance to the diet of . (Kennet, et al., 2009; Kuchling, et al., 2013)do not show morphological specializations compared to other
Roti island snakenecks can produce a foul-smelling musk to discourage predators, and can tuck their neck and head into their shell for protection. Except for humans, adults are they are believed to have few predators. Feral pigs (Sus scrofa) are known to eat eggs and adult turtles. Hatchlings might be eaten by wading birds and other medium-sized predators, if present on the island. (Kuchling, et al., 2013; Rhodin, et al., 2010)
Island residents used this species as a minor food source in the past. At present the turtle is in extremely high demand in the pet trade, so much so that this is a very urgent threat to the survival of the species. The capture and sale of these turtles has occurred since the early 1990s. (Kuchling, et al., 2013; Rhodin, et al., 2010)
There are documented no adverse effects ofon humans.
