A creature so rarely observed may spend half a century traversing ocean basins without a single documented human encounter. That longevity combined with rarity amplifies the mystery surrounding its life history.

Long lifespans paired with low reproductive rates create vulnerability to environmental change. Even minimal fishing pressure or ecosystem disruption could have outsized impacts on a species that replaces itself slowly.
