Yes, a grey seal can swim in the same water as the subject of Moby Dick. The range of gray seals is limited to parts of the northern hemisphere bordered by the Atlantic ocean. The subject of Moby Dick was a sperm whale. Sperm whales can be found in the north Atlantic, in addition to most other bodies of water on earth, so they could swim together.
