The most surprising thing to me was how deep mammals and even birds manage to get! The diving depths of emperor penguins, elephant seals, and narwhals are astonding.
- holoduke 5y agoI was surprised by the mentioning of the megamouth shark at 4200 meters. I thought they were at max 400m. Cannot find a proper source. But I find it hard to believe.

On 15 November 1976, the research vessel AFB-14 of the Naval Undersea Center (now the Naval Ocean Systems Center), Kaneohe, Hawaii, was conducting oceanographic research in waters about 42 km northeast of Kahuku Point, Oahu, at about 21°51'N and 157°46'W. From 1015 to 1415 Hawaiian Standard Time the ship had de-ployed two large parachutes as sea anchors at a depth of about 165 m in water with a bottom depth of approximately 4600 m. Edit: Now that I read parts of the source, the only mention of that depth (unless I missed something) is the one I included in my comment. I think that people mistook the depth of the water for the depth at which the shark was caught. Another part of the source says this (on page 22) : Apparently, when captured, Megachasma pelagios would have been in the upper depths (165 m) where these euphausiids are commonest at night, and quite possibly might have been feeding on them when it became entangled in the parachute.
