An open field guide
See which animals the library covers.
94 care introductions across 46 browsing categories, with setup checklists and a keeper’s notebook.
Understand the different guide types.
73 species introductions cover a named animal and link to more detailed husbandry sources. Read the stated life stage and scope before applying a reference.
14 group introductions cover related animals or hybrids. Identify your animal before choosing environmental targets; one setup cannot represent the whole group.
7 specialist introductions focus on identification, preparation and questions to resolve with experienced support. They are starting points for further research.
The finder and planner flag references that need an individual space assessment. Experience labels describe the care demands used by the finder; they do not certify suitability for a particular keeper.
Depth and review status
Coverage varies. Some introductions include adult planning dimensions and quick facts; others explain what must be established for the exact animal. A browsing category includes only the linked introductions below.
The articles are source summaries. Independent species review remains pending. The three measured build proposals have not been physically tested. Review status and changes appear on each article.
The current collection covers reptiles. If your species is absent, you can still record it in your notebook using Other species and request an introduction below.
| Category | Animals covered and scope |
|---|---|
| Ball pythons | Ball python This guide covers Python regius. Start with the individual’s feeding history and measured enclosure conditions. |
| Short-tailed pythons | Blood python · Borneo short-tailed python · Sumatran short-tailed python Currently covers three species: blood, Borneo short-tailed and Sumatran short-tailed pythons. Confirm the scientific name before choosing a guide; this selection is not an exhaustive short-tailed python inventory. |
| Carpet pythons | Carpet python The Morelia spilota complex includes different localities and adult sizes. This introduction explains the scope; it does not prescribe one setup for every carpet python. |
| Green tree pythons | Green tree python This introduction defines its coverage of green tree pythons. Resolve identity, locality, life stage and usable perches before selecting environmental targets. |
| Reticulated pythons | Reticulated python This introduction covers specialist ownership. Adult size and ancestry matter; a dwarf or super-dwarf sales label does not certify a small adult. |
| Burmese pythons | Burmese python Burmese pythons are giant constrictors that require individual housing, servicing and long-term care plans. |
| Other pythons | Angolan python · Black-headed python · Boelen’s python · Children’s python · Hybrid pythons · Macklot’s python · Olive python · Pygmy python · Rock pythons · Rough-scaled python · Scrub pythons · Spotted python · Timor python · Water python · White-lipped pythons · Woma python Browse the named animals below. “Other pythons” is a browsing category, not a shared care protocol. Stimson’s pythons are addressed explicitly in the Children’s python guide. |
| Boa constrictors | Boa imperator · True boa constrictor Boa imperator and Boa constrictor are distinguished here. Ask for the animal’s documented identity and locality rather than relying on “red-tail” alone. |
| Rainbow boas | Brazilian rainbow boa Current coverage is the Brazilian rainbow boa, Epicrates cenchria. Other rainbow boa species need their own identification and care assessment. |
| Sand boas | Kenyan sand boa Current coverage is the Kenyan sand boa. This is not a universal care sheet for every sand boa species. |
| Tree boas | Northern emerald tree boa · Amazon tree boa Northern emerald and Amazon tree boas have separate introductions. This selection does not cover every Corallus species; Amazon-basin emerald tree boas require their own assessment. |
| Rosy boas | Rosy boa This rosy boa introduction explains the locality and identity questions to resolve before planning the environment. |
| Dumeril’s boas | Dumeril’s boa This guide covers Acrantophis dumerili. Read its ownership and enclosure requirements before choosing an animal. |
| Other boas | Anacondas · Hispaniolan boa · Hybrid boas · Northern rubber boa · Solomon Island boas · Viper boa Explore the additional boa introductions in this collection, from rubber boas to anacondas. These animals have different space, climate and feeding requirements; each introduction identifies its scope. |
| Corn snakes | Corn snake This guide covers Pantherophis guttatus and includes a connected setup checklist. |
| Hognose snakes | Western hognose snake Current coverage is the western hognose, Heterodon nasicus. Eastern, southern and other animals called hognose snakes are not interchangeable with it. |
| Kingsnakes | California kingsnake · Mexican black kingsnake Separate introductions cover California and Mexican black kingsnakes. Identify other kingsnake species before applying either guide. |
| Milk snakes | Honduran milk snake Current coverage is the Honduran milk snake, with the scientific-name and trade-name limits explained in the guide. |
| Rat snakes | Beauty rat snake · Corn snake Current coverage includes beauty rat snakes and corn snakes. “Rat snake” spans many species and climates; these guides apply only to their stated scope. |
| Bullsnakes | Bullsnake This introduction covers the bullsnake within the Pituophis catenifer group. |
| Gopher snakes | Gopher snake · Bullsnake The gopher snake introduction and separate bullsnake guide distinguish locality and subspecies considerations. |
| Garter snakes | Common garter snake Current coverage is Thamnophis sirtalis. Diet and social housing should not be generalized across all garter snakes. |
| House snakes | African house snake This African house-snake introduction explains why a trade label may not establish the species. |
| Pine snakes | Pine snake Current coverage is Pituophis melanoleucus, with locality and legal provenance to establish before acquisition. |
| Other colubrids | Beauty rat snake · Common garter snake · African house snake · Gopher snake · Pine snake Browse the animals currently covered here. This collection is not a complete colubrid inventory and does not provide a shared diet or climate plan. |
| Bearded dragons | Bearded dragon Current coverage is the central bearded dragon, Pogona vitticeps. |
| Skinks | Blue-tongued skink · Schneider’s skink Current coverage includes scoped blue-tongued skinks and Schneider’s skinks. Tropical Indonesian blue-tongued skinks are not covered by a northern/eastern Tiliqua scincoides guide. |
| Chameleons | Veiled chameleon · Panther chameleon Separate guides cover veiled and panther chameleons. Other chameleons need species-specific climate and hydration planning. |
| Monitors | Ackie monitor · Black-throated monitor · Crocodile monitor · Mangrove monitor · Nile monitor · Black roughneck monitor · Savannah monitor · Tree monitors · Asian water monitor · White-throated monitor Start with exact identity and adult space. The entries distinguish dwarf, arboreal, terrestrial and semi-aquatic monitors; none certifies a generic monitor enclosure. |
| Tegus and related lizards | Argentine black-and-white tegu · Caiman lizard · Colombian tegu · Crocodile tegu · Western whiptail Tegus and related teiid lizards include terrestrial, climbing and swimming specialists. Choose the named animal below to understand its housing, food and care requirements. |
