02 · Editorial pipeline
How a care sheet gets from research to your screen
Every species sheet on IguanaNaut passes through the same four-stage pipeline, and the pipeline is published — keepers can see exactly who reviewed what, when, and against which evidence base. The aim is not a polished brochure. The aim is a document a working keeper can hand to a working keeper, with the receipts attached.
Stage one — the evidence base
Before a draft is written, the assigned editor assembles an evidence dossier: peer-reviewed papers where they exist, captive-breeder mortality logs from the IguanaNaut database, and any veterinary case series relevant to the species. Hobbyist forum posts are not cited. They may inform questions, but they are not evidence.
Stage two — the draft
A single author drafts the sheet against the dossier. Each husbandry claim — basking temperature, humidity cycle, UVB index, substrate choice, feeding cadence — is tagged with a citation tier, shown in the margin as a coloured bar.
-
Peer-reviewed. Source is a published paper in a recognised herpetological or veterinary journal. Tier marker is the primary green.
-
Breeder log. Source is a multi-keeper log from the IguanaNaut database or an equivalent published breeding record. Tier marker is the muted grey-green.
-
Editorial. Source is the editorial team's experience, vetted by the advisory board but not formally peer-reviewed. Tier marker is the terracotta accent.
Stage three — the 90-day keeper review
The draft is handed to a minimum of three independent keepers, none of whom know each other and none of whom are the original author. Each runs the protocol against the species for at least 90 days. Their notes — disagreements included — are published as a review appendix at the foot of the sheet.
Stage four — the timestamp
Every published sheet carries a Last reviewed date. Husbandry moves on; a sheet that has not been re-checked against current evidence within 18 months is flagged as overdue and queued for a revision cycle. The timestamp is a discipline, not a decoration.

05 · About the sheets
Languages, review cadence, authorship, requests
Short answers to the four practical questions a serious keeper tends to ask before clicking into a sheet for the first time.
- Which languages are the sheets available in?
- Through the partnership with the European Herpetological Society, sheets are translated into seven languages: English (canonical), German, French, Spanish, Portuguese, Polish, and Dutch. Translation coverage varies by species and is shown on each card. A new translation cycle runs every spring and autumn.
- How often is a sheet re-reviewed?
- Every published sheet carries a Last reviewed date. Husbandry moves on; a sheet that has not been re-checked against current evidence within 18 months is flagged as overdue and queued for a revision cycle. High-traffic species (leopard gecko, corn snake, ball python) are reviewed on a rolling 6-month schedule.
- Who actually writes the sheets?
- Sheets are drafted by the core editorial team of six full-time editors, reviewed by the 9-person advisory board (3 DVMs specialising in reptile medicine, 1 tenured herpetologist, and 5 senior breeders), and field-tested by a contributor network of 38 keepers, vets, and breeders. Authorship and review credits are listed at the foot of every sheet.
- What if the species I keep isn't listed?
- Email [email protected] with the binomial, your husbandry context (captive-bred, long-term, breeder), and any references you already trust. Requests are triaged against the species queue and, where evidence permits, added to the next production cycle. The protocols index also covers many cross-species techniques that work before a dedicated sheet exists.
