There are sometimes also sightings of gray seals, which live in the North Atlantic. Adults can measure 6 to 7 feet in length and weight 400 to 600 pounds. Harp seals, named for the harp-like markings that adults develop on their backs, live in the North Atlantic and the Arctic. Hooded seals are another Arctic species that can weigh as much as 800 pounds as adults.
Please note that there are no guarantees that you'll see many seals on any of the cruises. At times, there may be 20 or even 100 sightings, but on some cruises, just a few can be seen. If you're bringing children, let them know in advance that it's impossible to predict how many seals will be popping up out of the water.
