Gulper Shark vs Lanternshark: common questions
Which is more endangered, the gulper shark or the lanternshark?
The gulper shark is more endangered, classified as Vulnerable due to decades of targeted liver-oil fishing combined with extremely slow reproduction, while the lanternshark remains classified as Least Concern despite localised bycatch declines.
Why was the gulper shark fished so heavily, unlike the lanternshark?
The gulper shark has an unusually large, oil-rich liver containing high concentrations of squalene, historically valuable commercially, a specific target not associated with the lanternshark.
Does the gulper shark glow like the lanternshark?
Bioluminescent counter-illumination camouflage is specifically documented in the lanternshark, using rows of belly photophores, a trait not documented as a defining feature of the gulper shark.
