The red-eared slider × yellow-bellied slider (Trachemys scripta elegans × Trachemys scripta scripta)[http://www.projectnoah.org/spottings/6342399 Hybrid Red-eared Slider, YellowBelly Slider] Project Noah is an intergradation of a red-eared slider and yellow-bellied slider subspecies.[http://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1013&context=nwrcinvasive Managing non-native wildlife in Florida: State perspective, policy and practice p47]d'Orgeix, C. A., and E. N. Sismour. 2009. Trachemys scripta scripta (Yellow-bellied Slider) x T. S. elegans (Red-eared slider). Herpetological Review. 40: 363 Intergrade facial markings range from a yellow blotch behind each eye, which may join a yellow neck stripe forming a "C" figure when viewed from the left side to those with an almost indistinguishable amount of red in the eye blotch, to individuals that look similar to red-eared sliders with a red "ear" stripe that doesn’t join with a yellow neck stripe (see attached pictures). In addition, the number of black blotches on the plastron (underside of shell) varies in intergrades from two on the front scutes which is typical of yellow-bellied sliders, to a dark blotch on each scute which is typical of red-eared sliders. Intergrades are presumed to be omnivorous, but hatchlings and juveniles are more carnivorous than adults.Ernst, C. H., and Lovich, J. E. 2009. Turtles of the United States and Canada.
