No small white body spots; first dorsal dark above without white margin, second dorsal dark distally, narrow pale caudal edge and dark terminal tip. Jaw structure is diagnostic. Marine coastal demersal/benthopelagic habitats; IUCN gives surface to 100 m.
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
No small white body spots; first dorsal dark above without white margin, second dorsal dark distally, narrow pale caudal edge and dark terminal tip. Jaw structure is diagnostic.
Names and Classification
Valid species described2021; historical Andaman M.mosis records require reassessment, not a global synonymy of M.mosis.
Adult Size
IUCN reports to 109 cm TL. Original examined specimens 37.6–71.7 cm were immature; this series does not establish maturity size.
Distribution and Habitat
Eastern Indian Ocean, Myanmar and Thailand to Andaman and Nicobar Islands, India. Marine coastal demersal/benthopelagic habitats; IUCN gives surface to 100 m.
Feeding and Ecological Role
Species-specific prey composition unverified. Recently separated from broadly identified M.mosis; fishing pressure in a restricted coastal range is a conservation concern.
Reproduction and Life History
Reproductive mode details and fecundity not established in the accessible primary account.
Conservation
Vulnerable (IUCN global; Assessed 21 March 2022; published 2022). Global category; national protection and regional risk are separate. Older broad taxonomic concepts can make historical accounts misleading.
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: Adult maturity, diet, longevity, reproductive output and population size poorly known.
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.
