Ehrlich's terrapin is very similar to the yellow-throated terrapin. The difference between the two is that: the rear half of the plastron of Ehrlich's terrapin is wider than that of the yellow-throated terrapin; the former's plastron has dark brown horseshoe-shaped markings, and its branches on both sides are sometimes intermittent and incomplete, while the latter's plastron From no spots to completely dark brown, more often there is a large dark brown spot on each scute, but it is never horseshoe-shaped; the front edge of the plastron of E. The front edge is convex; the laryngeal scute groove and the anal scute groove of Ehrlich's terrapin are both longer, accounting for more than 13.1% and 12.5% ??of the length of the plastron respectively, while the yellow-throated terrapin is shorter, accounting for only 12.5% ??of the plastron length respectively. The long ones are 7.4%--10.8% and 8.8%--11.5%, etc. Lives in slow-flow sections or backwaters of mountainous streams at an altitude of 500m
