Sea Lion? or Seal?

(Click on post title to see customer video clip.) So, what is the difference between seals and sea lions anyway? 
From the web: Seals and sea lions are marine mammals called 'pinnipeds' that differ in physical characteristics and adaptations. 
Sea lions are brown, bark loudly, "walk" on land using their large flippers and have visible ear flaps. 
Seals have small flippers, wriggle on their bellies on land, and have visible holes for ears.

When you are out on the water with us in San Diego Bay, you'll see sea lions- for you Star Wars fans, they sound just like Tusken Raiders.
