Marine Wildlife of British Columbia?

I heard that the seas near British Columbia is super diverse in marine life, which i found surprising since Canada seems to be a more colder environment.

Question to those Canadians involved with marine biology or who have been in the oceans near British Columbia: could you describe to me the marine life that are found in the oceans near British Columbia? Specific species of fish, mollusks, crustaceans, marine mammals, sharks, etc?
