As of 2021, there is no particular data as to how many Mexican mud turtles exist. All we know is that turtles have been one of the most threatened groups of vertebrates. In fact, around 61% of the 356 turtle species in the world are already Threatened or Extinct. Although the population of the Mexican mud turtle is said to still be abundant, herpetological experts warn that there are still risks that this species might be Endangered.

Where does a Mexican mud turtle live?

The Mexican mud turtle is endemic to central and western Mexico, which are mostly found in shallow ponds, lakes, rivers, or tropical forest areas. They live at an altitude range between sea level and 7874 ft (2400 m).

What is a Mexican mud turtle's habitat?

Being aquatic species, Mexican mud turtles are inhabitants of various bodies of water where clean and oxygenated water is apparent. They also make their home through sandy and muddy areas where they hide in mud to rest.

Who do Mexican mud turtles live with?

How long does a Mexican mud turtle live?

Although there is no specific data on the longevity of Mexican mud turtles in the wild, the Kinosternon integrum was recorded to have lived for almost 19 years in captivity. More often than not, mud turtles are said to have a life expectancy of 50 years.

How do they reproduce?

Like other turtle species, the reproductive habits of the Mexican mud turtle are seasonal and correlated with weather change. The breeding season of this species starts just before the rainy season, in early May, and ends around September. However, Chelonian Conservation and Biology states that the reproduction timeline of K. integrum starts in late June and ends in late October, similar to the freshwater turtles in North America. The same study observed the population of Mexican mud turtles in Tonatico, Mexico (Tonatico estado de México). Rodrigo Macip-Ríos and Gustavo Casas-Andreu et. al. (2006) found that the average clutch size in Tonatico estado de México was four eggs, which is slightly lower than the findings of Iverson (1999) of 5.8 eggs.

Supporting the research of Iverson (1999), Chelonian Conservation and Biology further concluded that there is a positive relationship between the body and clutch size of Mexican mud turtles in Tonatico estado de México. On the other hand, there is a negative relationship between the clutch size and the egg size. This means that bigger females produce more eggs and the more eggs in a clutch would result in smaller egg size. Such a characteristic is true with other freshwater turtles and other ectotherm species like lizards and snakes.

What is their conservation status?

The Mexican mud turtle (Kinosternon integrum) is currently listed as Least Concern by the IUCN. However, Chelonian Conservation and Biology have raised debates on the conservation status of freshwater and terrestrial turtles, including the Kinosternon integrum. It states that the current status of these species should be reviewed and that it is necessary that the Federal Government collaborate with a herpetological specialist group. (Macip-Ríos et. al., 2015)

Some of the most notable people who studied and fought for the conservation of Kinosternon integrum in Mexico are: Rodrigo Macip-Ríos, Víctor Hugo Sustaita-Rodríguez, Gabriel Barrios-Quiroz and Gustavo Casas-Andeu, Xóchitl Aguilar-Miguel, Angeles Aparicio, Ivette Enríquez Mercado, Alejandro Montiel Ugalde, Eder Gaona-Murillo, and Taggert Butterfield.
