What depth, confirmed by satellite telemetry, can white marlin dives exceed when feeding deeply in warmer southern waters?

Answer

100 fathoms

Tracking data obtained via satellite telemetry reveals that white marlin engage in significantly deep foraging dives, particularly when hunting in warmer southern oceanic regions. These profound descents are characterized by distinctive V-shaped or extended U-shaped profiles. The recorded depth of these serious feeding excursions can consistently surpass the 100-fathom mark. This behavior suggests a strategic targeting of deep-water fish and cuttlefish populations. The mechanics of these dives imply that the marlin spots its intended meal silhouetted against the lighter water column from below, whereupon it executes a rapid ascent to intercept the prey at a predetermined depth, which explains why they are occasionally captured by anglers using deep-set baits meant for other species like swordfish.
