Small smooth legskate with elongated snout; verified voucher morphology needed against melanosoma. Marine deepwater slope species; type locality off northern Borneo at 450–456 fathoms.
Wildlife education
This record supports wildlife education. Aquarium-care questions are not assigned to this profile.
Wildlife education profile; reviewed natural-history sources do not establish a captive operating protocol.
Wildlife reference; no home-aquarium stocking recommendation or validated captive operating protocol is supplied. Public-aquarium photographs document living animals, not suitability for private keeping.
Outstanding care evidence
- Institutional lifetime husbandry and veterinary protocol
Identification
Small smooth legskate with elongated snout; verified voucher morphology needed against melanosoma.
Names and Classification
Anacanthobatis borneensis historical combination; do not automatically include doubtful nanhaiensis in synonyms. Also published under Anacanthobatis borneensis.
Adult Size
Adult maximum unresolved; published summaries conflict and large Okinawa specimens are misidentifications.
Distribution and Habitat
South China Sea and Taiwan; oversized Japanese records may represent melanosoma. Marine deepwater slope species; type locality off northern Borneo at 450–456 fathoms.
Feeding and Ecological Role
Species-specific diet unverified. Poorly known marine deepwater skate; encounter rates and post-capture survival uncertain.
Reproduction and Life History
Egg-laying skate; species-specific egg production, maturity and incubation largely unverified.
Conservation
Least Concern (IUCN global; 2020 global assessment, assessed 6 May 2020.). Global category; regional management and legal protection are separate. Older species accounts may retain superseded categories.
Responsible Observation
Observe without chasing, feeding, touching or obstructing the animal. Keep fins and equipment off resting rays and sharks; give sawfishes and wedgefishes room to move. Follow the site’s local wildlife rules and use responsible dive operators.
About the Photographs
No freely reusable photograph of a verified living specimen was found in this search. The target of at least three photographs remains unmet. Dead or preserved specimens, drawings and uncertain identifications were excluded.
Aquarium Suitability
Wildlife education only. This marine elasmobranch is outside home-aquarium stocking and care guidance. Wild range and diet are not a captive operating protocol; this profile does not infer tank dimensions, water settings, acquisition advice or an institutional welfare plan.
Evidence Gaps
Evidence gaps include: Longevity, diet, fecundity, abundance and geographic population structure.
A living record
Natural history, taxonomy and global conservation categories checked against the linked sources. Habitat measurements are not captive care settings. Each photograph has separate identity, living-status and rights evidence. Public content last reviewed October 17, 2026.
