In The Little Mermaid, Eric's parents are shown to be very loving and supportive of their son. However, they are also shown to be quite strict, especially when it comes to his studies. This is likely due to the fact that they want Eric to grow up and be successful in life.
Unfortunately, Eric's parents die in a tragic accident when their ship sinks during a storm. This leaves Eric all alone in the world and feeling completely lost. Thankfully, he eventually finds comfort and companionship with Ariel and her friends from under the sea.
