The Chain-fruit Cholla, also called the Jumping Cholla, is notorious for its spine clusters that detach explosively at the slightest touch and embed in skin, fur, or clothing with barbed hooks. This is not the plant 'jumping' but rather the weight of an animal brushing the stem causing the segment to snap off. The detached segments are carried away and root when dropped — a remarkably effective dispersal strategy. Long chains of persistent fruits give the tree its common name. Dense cholla forests in the Sonoran Desert are essential nesting habitat for cactus wrens and curve-billed thrashers.
