Oceanic, possibly occurring in depths between 150 and 1,000 m (Ref. 6871). Feeds on planktivorous prey such as euphausiid shrimps, copepods and jellyfish (Ref. 6871). May also eat small midwater fishes. Possibly less active than the basking and whale sharks (Ref. 6871). Its feeding habits and habitat suggest that it may be a rare catch in the future.
