About CrocodileVsAlligator.com
Independent crocodilian reference. Built and maintained by Digital Signet. Editorial position, primary zoological sources, and corrections process.
Why this site exists
Crocodile-vs-alligator disambiguation is one of the most common wildlife questions on the internet. The answer is genuinely interesting (snout shape, dentition, salt-gland physiology, taxonomic divergence approximately 80 million years ago in the late Cretaceous) but the information is scattered across Britannica explainers, PBS Nature, SeaWorld and Defenders of Wildlife pages, A-Z Animals, swamp-tour blogs, regional state wildlife agencies, and the peer-reviewed herpetology literature. The signal-to-noise ratio is low.
CrocodileVsAlligator.com consolidates the reference layer. Every claim is cited to a named primary source: IUCN Red List for conservation status, Erickson et al. 2012 PLOS ONE for bite force, the CrocBITE Worldwide Crocodilian Attack Database for fatality estimates, the Florida Fish and Wildlife Conservation Commission and US Fish and Wildlife Service for North American range, and supporting authorities at the Smithsonian National Zoo, San Diego Zoo Wildlife Alliance, Australia Zoo, National Geographic, and Britannica. Where the underlying data is uncertain (e.g. wild population estimates for sub-Saharan Nile crocodiles, or attack reporting completeness in the Indo-Pacific), the site says so.
The aim is to be the resource someone reaches when they want a real answer to "what is the actual difference between a crocodile and an alligator", "which is more dangerous", "how big do they get", or "what does the bite force figure actually mean".

Editorial position
CrocodileVsAlligator.com is a reference site. It is not a zoo, a wildlife conservation body, a tour operator, a veterinary service, or a substitute for licensed wildlife professionals in the field. It does not provide live attack alerts, individual animal tracking, or husbandry advice for captive crocodilians.
Brand names appearing on the site (Cajun Encounters, Airboat Adventures, Gatorland Orlando, Crocodile Hunter Lodge, tour operators in Kakadu and the Mara, etc.) appear for editorial specificity, not endorsement. There is no paid placement and no sponsored content. Where the site adds a future affiliate relationship (e.g. tour-booking referral), it will be disclosed in line with FTC guidance and marked clearly on the page.
The site is not affiliated with the IUCN, the IUCN SSC Crocodile Specialist Group, the San Diego Zoo Wildlife Alliance, the Smithsonian National Zoo, Australia Zoo, the National Geographic Society, Britannica, the Florida Fish and Wildlife Conservation Commission, the US Fish and Wildlife Service, or the Wildlife Conservation Society. Citations are descriptive, not endorsements.

Editorial principles
Real primary sources
Conservation status traces back to the current IUCN Red List assessment. Bite-force figures trace back to Erickson et al. 2012 PLOS ONE. Attack and fatality data trace back to the CrocBITE Worldwide Crocodilian Attack Database. North American range traces back to Florida Fish and Wildlife Conservation Commission and US Fish and Wildlife Service. Etymology and taxonomy cross-checked against Britannica, Smithsonian National Zoo, and San Diego Zoo Wildlife Alliance.
Wildlife reference, not safari guide
This site exists to disambiguate crocodiles from alligators and to compile factual species profiles. It does not provide live attack alerts, individual specimen tracking, captive-care husbandry, or veterinary care advice. The travel-guide pages identify ethical viewing locations and ranked operators; they are not bookings nor real-time availability.
No fabricated species data
Every numerical figure on the site (length, mass, lifespan, population estimate, bite force, fatality count) carries a named primary source. Where ranges differ across authorities, the site uses the most recent peer-reviewed measurement and notes the range. Where data is genuinely uncertain (e.g. wild population estimates for ranging species), the site says so.
Single-source freshness
A single LAST_VERIFIED_DATE constant in the source drives every freshness indicator: footer stamp, schema dateModified, hero badges, methodology timestamp. Rolling that constant requires re-checking the cited primary sources for revisions; cosmetic refreshes are not possible.
No paid placements
Brand names (Cajun Encounters, Gatorland, Crocodile Hunter Lodge, etc.) appear for editorial specificity, not endorsement. No paid placement, no sponsored content, no exchange of editorial mention for commercial consideration. Where a future affiliate relationship is added (e.g. a tour-booking referral) it will be disclosed in line with FTC guidance.
Not affiliated
Independent reference. Not affiliated with the IUCN, IUCN SSC Crocodile Specialist Group, San Diego Zoo Wildlife Alliance, Smithsonian National Zoo, Australia Zoo, National Geographic Society, Britannica, Florida Fish and Wildlife Conservation Commission, US Fish and Wildlife Service, or any tour operator or conservation body cited on the site.
Methodology in brief
The full methodology page documents every primary source, the calculation logic for the bite-force ranking and danger-ranking pages, the refresh cadence, the boundaries of what the site does and does not cover, and the corrections process.
Disclosures
- Independent reference site, not affiliated with any zoo, conservation body, or wildlife agency.
- No live affiliate or referral programmes on this site at the present review date. Future affiliate relationships will be disclosed in line with FTC guidance and marked on the page.
- No paid placements, sponsored content, or editorial mentions paid for by commercial parties.
- Site is built and edited by a human (Oliver Wakefield-Smith). Where AI assistance is used in the editorial process, the human editor verifies every cited claim against the named primary source before publication.
Contact and corrections
Email Digital Signet with the specific URL, the disputed claim, and the primary source you want the claim verified against. We aim to respond within 5 business days with either a correction (where the source supports the dispute) or an explanation (where the existing wording is correct).
Where a correction changes the substance of a recommendation or factual claim, we note the change on the affected page. The site LAST_VERIFIED_DATE is rolled forward only when a substantive review against the cited primary sources has occurred, not for cosmetic edits.
