흰머리독수리(Haliaeetus leucocephalus)는 미국의 국조이자 미국 자연 보전 성공의 상징으로, 날개 폭이 최대 2.4미터에 달하며 북미 전역의 수변 삼림과 습지에 서식한다. 주로 물고기를 포식하는 강력한 공중 포식자이자 청소 동물로, DDT 오염과 남획으로 1960년대에 멸종 위기에 처했으나 농약 사용 금지와 멸종위기종보호법 시행 이후 극적으로 개체수가 회복되었다.

Clostridium sporogenes is an anaerobic, endospore-forming bacterium in the family Clostridiaceae phylogenetically and morphologically closely related to C. botulinum type A but lacking the genes encoding botulinum neurotoxin. It is widely distributed in soil, sediments, and the gastrointestinal tracts of animals and humans, where it is considered a non-pathogenic member of the microbiome. The species epithet sporogenes refers to its characteristic production of abundant, conspicuous endospores. C. sporogenes is highly proteolytic, producing multiple proteases that break down proteins into amino acids and peptides, contributing to the decomposition of organic nitrogen in anaerobic environments. In food science, it serves as a surrogate organism in studies validating thermal processing conditions for low-acid canned foods — its heat-resistant spores are used as surrogates for C. botulinum in process safety testing without the biosafety concerns of using the toxigenic parent species. Research has also explored C. sporogenes as a vector for delivering anticancer prodrug-activating enzymes into hypoxic tumor microenvironments, exploiting its preferential germination in anaerobic tissue regions.
