Mauremys reevesii
In 3 days ~50% in a week ~80%
Mauremys reevesii, commonly known as the Chinese pond turtle, the Chinese three-keeled pond turtle, or Reeves' turtle, is a species of turtle in the family Geoemydidae, a family which was formerly called Bataguridae. The species is native to East Asia.
Alongside the Chinese softshell turtle, it is one of the two most commonly found species used for divination that have been recovered from Shang dynasty sites. While the species typically appears to have a brown shell, dark grey skin, with yellow markings on the neck and yellow irises, melanism is well documented in males, where the entirety of the animal including the eyes becomes completely black and the yellow markings are lost. Melanism only occurs in mature males over 7 years old. Old females may sometimes also develop darker shells and fewer markings.
Certain populations of Reeve's turtles may exhibit megacephaly. Megacephalic turtles have much larger and broader heads, and hypertrophied jaws muscles. In at least one other species of turtle, it appears that megacephaly may not be genetically linked, instead developing in individuals as a response to a heavily durophagous diet.

No species of the same family or order lives in Nagoya, so these are its closest relatives here: other reptiles.
Possible
About 20% of wildlife watchers report a Chinese Pond Turtle sighting in Nagoya on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 9 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Chinese Pond Turtle in Nagoya on a given day, against under 5% in September to April, the lowest months.
3rd of 5
Of the 5 cities where we can rate Chinese Pond Turtle sightings, Nagoya ranks 3rd at about 20%. The best odds are in Hiroshima (Japan, about 40%) and Osaka (Japan, about 20%).
GBIF citizen-science records
It is estimated from how often the Chinese Pond Turtle is recorded against all the reptiles logged in Nagoya (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
