In a remote stretch of rainforest on Canada’s Pacific coast, a unique population of wolves has taken to a life of the sea.
Along the wild Pacific coast of British Columbia – a misty wonderland of
craggy glacier-gouged shores and temperate rainforest – there lives a
population of wolves genetically and behaviorally distinct from the
rest. They’ve traded in deer and sheep and mountain goats for the bounty
of the sea. They’ve been known to swim up to eight miles to get from
the mainland to an island; they live on barnacles and herring roe, seals
and dead whales. Some 90 percent of their food comes directly from the
ocean…
These wondrous sea wolves swim for miles and live off the watery wilds

Horseshoe crabs can lay between 60,000 to 120,000 eggs. These eggs are laid in the sand or mud in batches of a few thousand at a
time, and take 2 weeks to hatch. Many are eaten by seabirds while
incubating. (source)

Here, a white-spotted rose anemone clings to and attempts to ingest a
moon jelly in Monterey Bay National Marine Sanctuary. Although the
jelly is twice the size of the anemone, most of the jelly is water, so
it’s not an impossibly large meal. While moon jellies are usually open
ocean species, sometimes oceanographic conditions bring them closer to
shore – and into the mouths of creatures like this anemone. (Photo: Steve Lonhart/NOAA)

Jellyfish serve as a habitat to many ocean creatures…
Jellyfish play a critical role in the lives of different marine
creatures. While they are used as a direct food source for many, some
use them as shelter (juvenile fish), some as a means of travelling from A
to B and some have a combined interest of travelling while snacking on
the microscopic parasites attached to the Jellyfish.
These symbiotic relationships are very intricate and are being
investigated by scientists. [source]
