Trenches
Deep-oceanic trenches are most abundant around the rim of the Pacific. Deep ocean trenches are surficial evidence for sinking of oceanic lithosphere into the mantle at a subduction zone.
By both overall depth, and by virtue of deepest trenches, the Pacific.
Giant squid primarily live in deep ocean trenches.

Deep ocean trenches are deep slits in the middle of the ocean. The pressure inside these trenches is unbearable. long, curved valleys along the edges of the ocean basin
