A central goal for Students Conserving Nature is to make the data that the team collects on the species available and free for any one who visits our website. These data include age class, sex, morphological measurements, microhabitat, and macrohabitat of turtles that we find or trap. This excludes any specific locality data. If you are interested in having access to the data, please see "Download data" at bottom of page.

Sinaloan thornscrub tortoise

(Gopherus evgoodei)

Total individuals observed: 57

Average male size: 221±23 mm (n=31)

Average female size: 236±16.9 mm (n=14)

Average subadult size: 114±29 mm(n=8)


Sierra box turtle

(Terrapene nelsoni)

This species has never been studied in the wild. They prefer pine-oak woodland habitat at higher elevations, but are also found in the tropical dry forest at lower elevations. They are terrestrial and associated with hill-slopes with complex understory vegetation. They have been eating dung beetles, mushrooms, and herbaceous vegetation. 


Endemic to Mexico. Data Deficient according to the IUCN (last assessed 1996). 

Total individuals observed: 54

Average male size: 132±9 mm (n=21)

Average female size: 134±8 mm (n=29)

Average subadult size: 84±11 mm (n=4)


Painted wood turtle

(Rhinoclemmys pulcherrima rogerbarbouri)

Very little is known about this species and our work represents the first intensive study of this species. Although this species is often associated with rocky streams in the tropical dry forest, they are often found atop or along hills. It appears that they are primarily herbivorous. 

The species has not been evaluated by the IUCN.

Total individuals observed: 37

Average male size: 152±12 mm (n=14)

Average female size: 169±12 mm (n=16)

Average subadult size: 94±26 mm (n=7)

The Mexican mud turtle (Kinosternon integrum) is the most wide ranging species of mud turtle in Mexico. They are frequently found in large rivers, small streams, or small water bodies. They spend the majority of the year estivating and are carnivorous. 


Endemic to Mexico. Not vulnerable according to the IUCN (last assesed in 2007). 

Total individuals observed: 204

Average male size: 166±20 mm (n=50)

Average female size: 155±12 mm (n=56)

Average subadult size: 81±22 mm (n=83)


Alamos mud turtle

(Kinosternon alamosae)

The Alamos mud turtle is known to exist in temporary aquatic habitats such as season pools and cattle tanks. So far, this species has not been found in permanent waterbodies. It appears that this species is primarily carnivorous, while considerable plant material is also ingested.

Average male size: 119±9 mm (n=15)
