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.

Categories and available introductions

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 pythonsGreen tree python

This introduction defines its coverage of green tree pythons. Resolve identity, locality, life stage and usable perches before selecting environmental targets.

Reticulated pythonsReticulated 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 pythonsBurmese python

Burmese pythons are giant constrictors that require individual housing, servicing and long-term care plans.
