This record notes the source location and content hash of "Wildlife and Working Animals｜Species / Breeds and Lifespan", so the text can be checked against the original.

How to use this record to verify

This record exists so that anyone can check for themselves whether the text has been altered. Every chapter of the veterinary encyclopaedia carries a starting line number and a content hash (the first 16 characters of its SHA-256). Recompute the hash over the original chapter: if it matches the value recorded below, what is published here is identical to the source chapter. The source list at the end is the authoritative material cited by that chapter — a chapter-level correspondence, meaning those sources underpin the chapter as a whole rather than mapping sentence by sentence. This is educational information and cannot replace a practising veterinarian; in an emergency, seek care immediately.

This record notes the source location of "Wildlife and Working Animals｜Species / Breeds and Lifespan | Evidence chain": the section beginning at line 81 of `29-獨立軌-野生動物園工作動物.md` in the veterinary encyclopaedia. The SHA-256 of that section (first 16 characters) is `3a504b7613e59d51`, which anyone can recompute to confirm the content has not been altered.

FAQ

Do zoo animals live longer than animals in the wild?
Not necessarily. Most mammals, reptiles and birds do live longer in captivity thanks to veterinary care and the absence of predators, but elephants are an important counterexample: a peer-reviewed study reports that the median lifespan of elephants in European zoos is about half that of conspecifics in protected populations in range countries.
Guide dogs work for 8.5 years. Is that their lifespan?
No, that is years of service. The study reports that the majority (84%) of guide dogs retire after about 8.5 years of work. The retirement thresholds for other working roles such as police, search and rescue and detection dogs may differ, and in practice they depend on institutional rules and the degree of occupational wear on the individual.
Can I look up one general figure for the lifespan of wild animals?
No, lifespan varies enormously between species. The direction that "lifespan in the wild is generally far shorter than in captivity" broadly holds for most small wild animals, but it is not universal; the allowlisted sources do not provide species-by-species comparison figures, and applying a single ratio of your own is not permitted.
