Krill swarm inside a giant
kelp forest at Islas Diego
Ramírez, 60 nautical
miles southwest of Cape
Horn. Krill form the base
of an enormous food
web, supporting fish,
penguins, sea lions, fur
seals, whales, and—atop
the web—orcas, among
the ocean’s most formi-
dable predators.
Giant kelps
continue to
grow once
they reach
the surface,
creating a
canopy through
which sunlight
filters as if
through the
stained glass
of a cathedral.
