It is native to Baja California, Sinaloa and Sonora in Mexico.[1] DescriptionThe Baja California Slider, also known as the Black-bellied Slider, is a medium sized turtle and identified for their clawed digits, non-elephantine hind limbs and a wide-colored suborbital patch. They have smooth shells, rounded posteriorly and straight interiorly. These shells are longer than they are wide, have a low later profile and can reach up to 37 cm (14.5 inches) in length. On the ventral side of the shell is yellow with symmetrical black markings. Dorsally the shell is dark in color with the vertebral, costal and marginal scutes having dark black spots surrounded by lighter margins. The Baja California Slider has a large, triangular shaped head which is covered by smooth skin. They have protruding non-hooked snouts where the nostrils are located decently high and large eyes. The top of the head is olive colored with indistinct pale lines while the chin and throat are lighter with central yellow markings; there is a pair of yellow stripes that extend anteriorly across the local jaw and onto the upper jaw. Their tails are moderately long while male’s tails being longer than females. The bodies are covered with multiple yellow stripes including the forelimbs, not the hind limbs.[3] Habitat and ActivityThey prefer larger bodies of water with muddy bottoms, often seen basking on emerged rocks or floating logs. Most activity takes place between mid-March and October as well as the winter months by burying themselves into the mud.[3] GeographicThe Baja California Slider has an exceedingly limited geographic range, currently found from San Ignacio southward into Baja California Sur. They were endemic only to the San José Rio basin in the greater Cabo San Lucas area (where they are now exceedingly rare due to over fishing) but as early as the late 1700’s they were transported northwards by natives to provide a continuing food source. They are still consumed today in the remote areas of Baja by native people. Although they are extremely wary of humans being very difficult to approach and are high maintenance, they make good house pets.[3] Subspecies
