모의고사 문제인데요,
보다가 헷갈리는 부분이 있어서요^^;

bactrian camels don’t live in shifting sahara sands but in central and east asia’s rocky deserts. they have two humps storing fat which can be converted to water and energy when food is not available. as their fat runs out, the humps become floppy and loose. bactrians rarely sweat, helping them conserve fluids for long periods of time. their bushy eyebrows and two rows of long eyelashes protect their eyes. big, flat footpads help them navigate the rough rocky areas. the only truly wild camels that still exist are bactrian camels. these herds survive in the gobi desert, but there are less than 1,000.

중간에 them 부분이요,
주어가 bactrian이고, them이 가리키는 대상도주어와 동일한 것 같은데,,
그럼 themselves가 아닌가 싶어서요~
