Recognition and identity Evidence that the subject is a snake and that any narrower identification is justified.
Snake recognition
Observable anatomy and alternatives to the snake classification.
Diagnostic anatomy
Record visible scales, body form, head features and tail configuration, distinguishing absent features from features that could not be seen.
- Which observed anatomical features support recognising this subject as a snake? definition
- What evidence distinguishes it from a legless lizard, caecilian, worm or shed skin? boundary
Taxon and individual
Confidence in taxonomic identification and continuity between encounters.
Identity evidence
Associate identification with locality, diagnostic observations and a traceable reference or expert assessment; keep individual matching separate.
- Which reference or expert assessment supports the proposed taxon, and which alternatives remain? provenance
- What markings, custody records or other evidence justify treating successive observations as the same individual? boundary
Body condition and life stage The snake's physical condition, shedding observations and developmental or reproductive context.

Dimensions, visible injuries and the location and progression of shedding concerns.
Condition and shed record
Record comparable size observations and visible skin condition, including suspected retained shed near the eyes or tail tip without attempting removal.
- What length, mass or body-profile observations are available, and how were they obtained? measurement
- Where are visible lesions or suspected retained shed, and how have they changed between dated observations? measurement

Life-stage evidence
Separate known history from inferred maturity, sex or reproductive condition.
- What dated history or qualified assessment supports the recorded life stage, sex or reproductive condition? provenance
- Which apparent changes could reflect feeding or body condition rather than reproduction? boundary
Behaviour and environmental needs Movement, refuge use, thermal context and feeding observations needed to interpret the snake's state.
Activity and microhabitat
Observed behaviour in relation to temperature, cover and opportunities to move away.
Activity in context
Record posture and locomotion alongside immediate conditions without assigning a cause from one observation.
- What movement, posture or refuge use was observed, for how long and under what disturbance? measurement
- What temperatures and access to cover were recorded at the snake's location, and by what method? measurement
- What additional evidence is needed before interpreting low activity as a condition requiring intervention? boundary
Feeding and water access
Documented intake and access conditions interpreted against verified taxon requirements.
Intake history
Track feeding events, refusals, regurgitation and water availability while separating observed facts from keeper reports.
- What feeding, drinking or regurgitation events were observed or reported, and when? provenance
- For a captive snake, what verified taxon-specific guidance supports changing prey provision or water access? action
Encounter risk and intervention Evidence and authority governing proximity, custody, handling and referral.
Venom and exposure
Separate taxon-linked venom information from the immediate possibility of contact.
Hazard with uncertainty
Retain unresolved venom status and record barriers, proximity and reported contact without relying on head shape or colour alone.
- What reliable taxon identification and source support the venom hazard assessment, or does it remain unresolved? provenance
- Can people or domestic animals reach the snake, and what barriers or escape routes are present? boundary
- What immediate access restriction or qualified-response referral is justified by the observed encounter? action
Custody and qualified action
Responsibility, competence and applicable constraints on intervention.
Intervention basis

What it is Filled
A snake is a member of the squamate clade Serpentes (Ophidia): an elongate, scaly, limbless reptile with a long series of precloacal vertebrae, a highly kinetic skull whose mandibular rami act independently, a deeply forked tongue serving the vomeronasal organ, a transparent spectacle in place of a movable eyelid, and no external ear opening; some lineages deliver venom through specialized fangs.
In scope
- Recognition as a snake and evidence supporting more specific identification
- Body dimensions, integument, injuries and shedding condition
- Life stage, reproductive indicators and feeding history
- Behaviour, movement and immediate thermal and shelter conditions
- Venom uncertainty, exposure opportunities and handling constraints
- Wild, captive or escaped status and responsibility for care
Out of scope
- Snake population dynamics and conservation programmes
- Complete reptile taxonomy and species descriptions
- Habitat ecosystems and their wider food webs
- Design and operation of enclosures or wildlife facilities
- Human or animal bite diagnosis and medical treatment
- Venom chemistry and antivenom manufacture
Why it exists Filled
Enable an AI agent to recognise a snake, assess its condition and encounter context, and choose justified observation, care or specialist intervention.
Distinguishing features Filled
- Check whether the elongated, apparently limbless body bears reptilian scales; body outline alone cannot distinguish a snake from a worm or caecilian.
- For confusion with a legless lizard, record visible eyelid and external ear-opening evidence, including whether either feature could actually be resolved; apparent absence in a poor image is inconclusive.
- Record the head, underside and tail configuration against a geographically relevant identification reference; do not assume that every snake has conspicuously broad belly scales.
- Distinguish a whole animal from a shed skin, detached body part or replica using continuity of anatomy and direct evidence of tissue or spontaneous movement; immobility alone does not establish death.
What robots and AI may and may not do Filled
Must not
- Encourage anyone to handle, catch or kill a snake.
- Tell a bitten person a snake is harmless when its identity is uncertain.
- Advise first aid for snakebite that delays emergency treatment.
- Help trade in snakes or their parts against wildlife law.
Only with a human decision
- Any decision to capture, relocate or kill a snake.
- Treatment decisions after a bite, which belong to clinicians.
May
- Observe, photograph and report snakes from a safe distance.
- Help identify a snake from photographs and stated location, with uncertainty given.
- Point people to emergency services after a snakebite.
Moral aspects Filled
- Snakebite kills and disables many people, mostly in poor rural areas.
- Snakes are often killed out of fear, harming species and ecosystems.
Who is affected
- The snake itself
- People at risk of bites
- Keepers of captive snakes
Owners Filled
Steward
Nobody: wild and protected by law in many places; keepers answer for captive snakes.
