Wildlife education and professional assessment
Wildlife reference: not recommended for home aquaria. The reviewed sources describe taxonomy and natural history, not a validated home-aquarium operating protocol. Capture, decompression, transport and research holding are species- and life-stage-specific; a photographed specimen does not establish long-term aquarium suitability.
Reviewed 2026-10-12. This is an applicability assessment, not a captive-care protocol.
Identity and Classification
Coryphaenoides armatus belongs to Macrouridae in Gadiformes. The gallery retains its source identification; modern taxonomic records and natural-history sources are listed below.
Distribution and Habitat
Widely distributed in the world's deep oceans. Deep slopes and abyssal seabed; do not imply hadal residency.
Feeding and Ecology
Predator and scavenger; larger fish eat squid and fishes, while small specimens consume more crustaceans.
Depth and the Hadal Boundary
Hadal habitats conventionally begin around 6,000 metres, beyond the abyssal zone. The reviewed evidence does not establish this photographed taxon as a hadal-trench resident. Deepwater species may occupy midwater, slopes or bottom habitats, and their depth ranges can change with size or time of day.
Evidence and Image Limits
Museum specimens, anatomical diagrams, aquarium displays and photographs of living wild animals provide different kinds of evidence. Captions distinguish them. Colours and body condition can change after capture or preservation, and a historical drawing is not a living-animal photograph. The leading photograph is source-identified Coryphaenoides armatus at Davidson Seamount. The existing anatomy diagram remains available. Other supplied grenadier photographs identify C. acrolepis, C. leptolepis, C. yaquinae or an unidentified Macrouridae fish, and are not presented as this species.
Conservation Context
No current global conservation category was independently assessed in this intake. Habitat observations and photographs do not establish abundance or population trend. Consult the linked research and current regional assessments for conservation or fisheries decisions.
Aquarium Suitability
Wildlife reference: not recommended for home aquaria. The reviewed sources describe taxonomy and natural history, not a validated home-aquarium operating protocol. Capture, decompression, transport and research holding are species- and life-stage-specific; a photographed specimen does not establish long-term aquarium suitability.
Abyssal Grenadier in Canada
Atlantic Canada: documented deepwater capture. Caught by traps on continental slope off Nova Scotia in August 1991. Reviewed occurrences are a supported subset of the range; photographs may have been taken elsewhere.
