New Zealand Lanternshark Jaw w/Data Ex. Dr Gordon Hubbell

NO INTERNATIONAL SHIPPING New Zealand Lanternshark Jaw with Data (Etmopterus baxteri) This is a shark that glows in the dark — and that alone sets it apart from virtually everything else in a jaw collection. The New Zealand Lanternshark is a bioluminescent deepwater species found at depths most fishing gear never reaches, which is precisely why a jaw with collection data from Dr. Gordon Hubbell's archive is the kind of thing that stops people cold. Known also as the Giant Lanternshark, it is the largest known luminous vertebrate — a title that deserves far more attention than it gets. Species & Classification Scientific Name: Etmopterus baxteri (Garrick, 1957) Common Names: New Zealand Lanternshark, Giant Lanternshark, Baxter's Dogfish Family: Etmopteridae (Lanternsharks) Order: Squaliformes Etymology: Etmopterus refers to the knife-like or grooved nature of the species; baxteri honors the collector and naturalist associated with the type specimens described from New Zealand waters Biology & Physical Characteristics Grows to a common length of 75 cm — notably large for a lanternshark, earning it the alternate name "Giant Lanternshark" Sharkwater Maximum recorded longevity of 57 years in the wild — an extraordinarily long lifespan for a shark of this size Senescence Like all lanternsharks, produces bioluminescent light through photophores concentrated on the belly, functioning as counter-illumination to camouflage the shark against residual downwelling sunlight when viewed from below Sharkwater Two dorsal fins with spines; no anal fin; bathydemersal body form adapted for deep-sea life Female sexual maturity reached at approximately 30 years of age — an exceptionally slow life history Senescence Habitat & Distribution Mainly found off the coast of New Zealand; also found in southern areas of Australia and Africa Wikipedia Depth range of 878–1,427 m; strictly bathydemersal Shark-References — one of the deepest-dwelling lanternsharks in the genus Occurrence in the Western Central Pacific is uncertain Shark-References, making any confirmed locality data scientifically valuable Lives in complete darkness at depth, navigating and hunting by bioluminescence and electroreception Diet & Behavior Feeds on small fish and invertebrates; uses counter-illumination bioluminescence to stalk prey by blending into background light Sharkwater Like related lanternsharks, likely feeds on mesopelagic cephalopods, lanternfishes, and crustaceans Bioluminescence is hormone-controlled, emitted through ventral photogenic organs called photophores; researchers have linked daily vertical migration to following an iso-lume Wikipedia Reproduction Ovoviviparous; embryos feed solely on yolk; exhibits distinct pairing with embrace during mating Shark-References Litter size of approximately 11 pups; interbirth interval of approximately 3 years Senescence Combined with late maturity and long lifespan, this species is among the slowest-reproducing sharks known — making every specimen historically significant Conservation Status Listed as Least Concern by the IUCN, largely due to its extreme depth habitat which places it largely beyond the reach of commercial fishing gear Sharkwater Despite low direct fishing pressure, the species' extremely slow reproductive rate and late maturity make any population disturbance difficult to recover from Deep-sea trawling remains a potential incidental threat throughout its range Misc. & Collector Facts The New Zealand Lanternshark holds the extraordinary distinction of being the largest known bioluminescent vertebrate on Earth — a biological superlative that belongs on any specimen tag A maximum recorded lifespan of 57 years Senescence means the individual behind this jaw may have been alive for longer than many of the collectors who will admire it Jaw specimens from bioluminescent sharks are exceptionally rare in the private market — the combination of extreme depth habitat, remote New Zealand distribution, and Hubbell provenance makes this a genuine one-of-a-kind piece "With data" includes collection locality and specimen documentation — critical for a species whose occurrence outside New Zealand remains scientifically uncertain Dr. Gordon Hubbell provenance adds significant authentication and collectibility value Ideal for: deepwater shark collectors, bioluminescence enthusiasts, Squaliformes specialists, natural history centerpiece displays, museum-quality specimens
