Credits

Wikapi’s cards are made of open data: photos by naturalists, and observations and measurements published by researchers around the world. Thank you to all of them.

Card photos

iNaturalist, or Wikimedia Commons as a fallback

Each card shows a photo of the species published on iNaturalist by a naturalist, under the licence they chose. Wikapi now only picks photos whose licence allows any use, including commercial use: CC0, CC BY, CC BY-SA or public domain. Photos picked earlier under a NonCommercial (NC) or NoDerivatives (ND) licence are being replaced with each update.

When iNaturalist has no freely licensed photo of a species, its card uses a photo from Wikimedia Commons, under the same licences.

Each photo’s credit is in its card’s details: tap a card in your collection, the catalogue or the market, or open its page. Under the scientific name, a line gives it in full:

Photo: © Author’s name · CC BY 4.0 · cropped

  • The author’s name links to the original photo.
  • The licence links to its text. iNaturalist photos use version 4.0 licences; Wikimedia Commons photos keep the version the author chose.
  • “Cropped”: the photo is cropped, sometimes enlarged, to fit the card’s medallion. A CC BY-SA photo stays under the same licence once cropped.

Packs

Each pack’s window shows a photo of a card of its type, and the Vivant pack (home screen, welcome booster) shows the okapi, Wikapi’s mascot. Their credits:

Legendary card images

Wikimedia Commons and iNaturalistImages: 5

When a Legendary’s photo doesn’t show the whole animal on its own (skeleton, fossil, specimen, extinct species), or its licence doesn’t allow commercial use, its card shows another image: a reconstruction or a photo from Wikimedia Commons, or another photo from iNaturalist. All of them are cropped to a square.

The numbers behind the cards

iNaturalist, GloBI, adult body mass, Wikipedia
  • iNaturalist: the species, their classification and their common names (open data, CC0), the number of observations (popularity, which counts towards the stats) and the global IUCN Red List status, which sets the rarity, as published by iNaturalist.
  • GloBI (Global Biotic Interactions): what each animal eats, which sets the predator index and the diet. GloBI brings together datasets published by their authors, each under its own licence. Poelen, Simons and Mungall (2014), Ecological Informatics 24: 148-159.
  • Adult body mass (size counts towards the stats):
    • AVONET, Tobias et al. 2022, Ecology Letters (CC BY 4.0)
    • Amniote life-history database, Myhrvold et al. 2015, Ecology (CC0)
    • SquamBase 1.0, Meiri 2024 (CC0)
    • AmphiBIO, Oliveira et al. 2017, Scientific Data (CC BY 4.0)
    • FishBase v25.04, Froese and Pauly (CC BY-NC 4.0, non-commercial use)
    Without published data, Wikapi estimates an order of magnitude by family or by order.
  • Wikipedia: each card’s details show the start of the species’ article, under the CC BY-SA 4.0 licence, with a link to the article and to its authors. Wikidata (CC0) links each iNaturalist species to its article.
