Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an AI agent to recognise an electric ray, distinguish taxon-level knowledge from observations of individuals and populations, assess condition and electrical hazards, and choose evidence-supported actions.
An electric ray is a marine cartilaginous fish of the group traditionally classified as Torpediniformes, distinguished by paired electric organs derived from muscle beside the head that produce discharges used in prey capture and defence.
It can be Identify an observed animal using documented characters and flag cases requiring specialist confirmation.; Attach electrical observations to an individual and measurement context without provoking a discharge for identification.; Compare observed condition with a species- and life-stage-appropriate baseline.; Map verified occurrences and distinguish local observations from supported native-range claims.; Determine whether observation, sampling, relocation or release requires specialist procedures and jurisdiction-specific authorisation.; Select an encounter response using animal condition, electrical uncertainty and an applicable species-specific protocol..
Distinguishing features
Identification should establish both ray body organisation and paired electric organs; a rounded disc alone is insufficient.
Distinguish an electricity-generating organ from electroreception: detecting an electric field does not establish an ability to deliver an electric discharge.
Check an authoritative identification key for electric-ray characters before interpreting an encounter as a stingray injury or another ray interaction.
Separate electric rays from electric eels using body organisation and taxonomic identification rather than the shared ability to generate electricity.
Do not reject an electric-ray identification solely because no discharge was observed; record observation conditions and identification evidence separately.

- Electrical equipment inspired by electric rays
- Clinical treatment of human injuries following an encounter
Characteristics
- Taxonomic identification and record level
- Accepted taxon and rank; authority and date; identification confidence; taxon, population or individual The common name must not be treated as one species or used to attach population observations to the entire grouping.
- Taxonomic reference alignment
- GBIF and NCBI identifiers where available, with source version and unresolved mismatches Allows records to be reconciled without assuming different taxonomic services use identical boundaries.
- Disc and body dimensions
- Disc width and total length in centimetres; mass in kilograms; method and uncertainty Supports identification and condition assessment while keeping unlike size measurements separate.
- Electric-organ evidence
- Taxonomically expected, directly documented, uncertain or unassessed; evidence method Separates an anatomical observation from an inference based on identification.
- Discharge observation
- Potential difference in volts, current in amperes, pulse duration in milliseconds and repetition rate in hertz where measured; electrode geometry, load and water conductivity An electrical reading is interpretable only with its measurement conditions and cannot alone establish encounter risk.
- Life stage and reproductive condition
- Source-defined life stage; sex and maturity where established; reproductive condition or unknown Size, behaviour and vulnerability must be interpreted in relation to development and reproduction.
- Habitat and occurrence
- Georeferenced occurrence, date, depth in metres, substrate, water temperature in degrees Celsius and salinity with stated scale Connects an observation to local conditions without generalising one species' habitat to all electric rays.
- Physical and behavioural condition
- Observed injury, ventilation, posture, movement and feeding response; baseline and uncertainty Supports welfare decisions without treating discharge presence or absence as a complete health assessment.
- Conservation and protection context
- Taxon-specific assessment category, assessment year, geographic scope and applicable legal jurisdiction Conservation assessments and legal restrictions apply to particular taxa and places, not automatically to the common-name grouping.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 26 questions.
Identity and organism boundaries Resolve what electric ray denotes and which biological entity a record describes.
A common-name grouping cannot safely inherit a single binomial, range or conservation status.
Taxonomic resolution
Connect the registered name and any identification to a documented classification.
Accepted electric-ray placement
Record the taxonomic coverage of electric ray and retain authority, date and reference identifiers for narrower identifications.
- Which authoritative classification defines the taxa included under electric ray, and which version was consulted? definition
- For an identified species, what are the accepted binomial, authority, date and available GBIF and NCBI identifiers? provenance
Identification and record level
Separate diagnostic evidence from the entity to which observations apply.
Diagnosis and observation subject
Require evidence for electric-ray identification and explicitly distinguish taxon, population and individual claims.
- Which documented anatomical characters distinguish this animal from locally occurring non-electric rays and other electric fishes? definition
- Does this record describe the whole taxon, a geographically bounded population or one observed individual? boundary
Electric organs and discharge Represent the distinctive electrical apparatus and the evidence needed to interpret its output.
Electrical capability is central to recognition and encounter decisions, but anatomical capability, measured output and behavioural use are different claims.
Electric-organ anatomy
Document the paired electric organs at the level supported by species-specific evidence.
Organ presence and development
Separate expected electric-organ anatomy from direct observations and unresolved developmental variation.
- What source establishes the location and structure of the paired electric organs for this taxon? provenance
- Is organ development or functional capability established for this individual's life stage, or merely inferred from adult descriptions? boundary
Discharge measurement and context
Interpret electrical observations using recording conditions and the animal's behaviour.
Interpretable discharge record
Keep measured electrical quantities, apparatus and behavioural interpretation together without assuming that every discharge serves the same function.
- What voltage, current or pulse timing was measured, and under what electrode placement, load, water conductivity and instrument settings? measurement
- What observed sequence supports interpreting the discharge as feeding-related, defensive or of unresolved function? provenance
- Can the required information be obtained from existing evidence or passive observation without inducing a discharge? action
Life history and condition Interpret development, reproduction, feeding and welfare at an appropriate taxonomic resolution.
An electric ray's size or discharge behaviour alone cannot establish maturity, reproductive state or health.
Development and reproduction
Record life-stage and reproductive evidence without transferring unsupported traits between species.
Stage, sex and reproductive evidence
Use documented criteria for developmental stage, sexual dimorphism, maturity and reproduction.
- Which species-specific characters or measurements support assigning sex and life stage, and what remains unknown? measurement
- What sources establish reproductive mode, maturity criteria and any seasonal reproductive pattern for this taxon? provenance
Feeding and welfare
Connect feeding observations and physical condition to an appropriate baseline.
Feeding performance and condition
Record prey interactions, electrical behaviour and signs of impairment while separating observation from diagnosis.
- What prey capture or feeding behaviour was directly observed, including any associated discharge, and under what conditions? measurement
- Which observed injuries, ventilation changes or movement abnormalities warrant specialist assessment under an applicable protocol? action
Habitat, conservation and encounters Connect electric rays to their environment, population evidence and decisions during human contact.
Range, threats and permitted interventions depend on species and place, while electrical capability changes how encounters must be assessed.
Range and habitat evidence
Distinguish verified occurrence from inferred distribution and environmental preference.
Local occurrence and supported range
Retain identification quality and environmental context for occurrences used to describe distribution.
- Which verified records support this taxon's native range, and where are boundaries uncertain because identification or sampling is weak? provenance
- What depth, substrate, temperature and salinity accompany this observation, and do they represent one encounter or repeated habitat use? measurement
Population status and human contact
Link conservation evidence and encounter circumstances to justified intervention.
Assessment and encounter response
Keep dated conservation assessments distinct from local condition, and ground contact decisions in suitable electrical and animal-welfare procedures.
- What is the identified taxon's IUCN assessment category and assessment year, and what evidence establishes pressures on this local population? provenance
- For this free-swimming, stranded, captured or captive animal, which applicable protocol and legal requirements govern observation, handling or release? action
- What uncertainty about identification, discharge capability or animal condition requires specialist involvement before intervention? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- Stingray - Stingrays belong to a different ray lineage and commonly defend themselves with a venom-bearing tail spine; electric rays have specialized paired electric organs.

- Electric eel - Electric eels are freshwater bony fishes of the knifefish lineage; electric rays are marine cartilaginous fishes.
- Electric-ray species - A species is a particular taxon within the broader electric-ray group; its range and conservation assessment cannot automatically be applied to every electric ray.
- Individual electric ray - An individual is one organism with its own age, sex and condition; a population comprises members of a species in a defined area.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of electric ray this model covers, and on what evidence? provenance
