They are mostly appear in groups, for the most part 4-8 animals but sometimes you will find larger groups. I have only encountered single animals when they are in the water, they are not as difficult to get close to, but they are a risk to shot because 50% sink right away when shot. If you shot at one individual in a group the others are gone before the first one hits the ground, so you seldom get a chance to shoot a double. And if you miss your first shot, your chances are blown, and you will have to find a new group of seals. But this is how they behave where I live in Norway, further north it may be different, I`m not sure.

I will try to get some pictures and a description of my "seal rifle" later.
