About JaguarVsPanther.com
An independent wildlife reference site explaining the most-asked questions about jaguars, panthers, and the four different animals that share the panther name. Editorial focus on disambiguation, with inline citations to IUCN Red List, USFWS, Florida FWC, and peer-reviewed primary literature.
Why this site exists
The question "is a panther a jaguar?" gets asked thousands of times a month, and the answer scatters across Wikipedia, Britannica, A-Z Animals, NatHab, Panthera.org, regional state wildlife agencies, and the peer-reviewed wildlife literature. The signal-to-noise ratio is low. Different sources give different lists of which animals count as a "panther." Several conflate melanistic jaguars with melanistic leopards. Almost none cleanly explain the four-different-animals reality.
JaguarVsPanther.com consolidates the reference layer with citations to the IUCN Red List, USFWS Florida Panther Recovery Program, Florida FWC population estimates, Schneider et al. 2012 (PLOS Genetics) on MC1R-delta15 jaguar melanism, Eizirik et al. 2003 (Current Biology) on ASIP leopard melanism, Wroe et al. 2005 (Proceedings of the Royal Society B) on big-cat bite force, Johnson et al. 2010 (Science) on the Florida panther genetic rescue, and Mooring et al. 2020 (Journal of Tropical Ecology) on melanism prevalence in Costa Rican jaguars.
The editorial position is plain: "panther" is not a species. It is a common name used for at least four different animals - black jaguars, black leopards, Florida panthers, and mountain lions - and the only useful first question is geography.
Who builds this
JaguarVsPanther.com is built and maintained by Oliver Wakefield-Smith at Digital Signet, an independent reference publisher. Editorial work is hands-on: every species range fact, every melanism citation, every IUCN status line is checked against the primary source before it goes live, and every page carries the LAST_VERIFIED date so readers can see how fresh the review is.

We document range, population, melanism genetics, conservation status, and disambiguation. We do not give live-attack advice, real-time animal-tracking, vet/husbandry guidance, or tour-booking recommendations.
Every weight, length, bite-force figure, population estimate, and IUCN status comes from a named, dated primary source. If a number is contested or a range is wide, we say so.
One LAST_VERIFIED_DATE constant in src/lib/schema.ts drives every footer stamp, hero badge, and JSON-LD dateModified across the site. Currently May 2026.
