¿Caimán o cocodrilo? (Alligator or Crocodile?)

What’s the difference between a seal and a sea lion? These “second cousins” of the sea look similar, but there are many ways to tell these creatures apart. From ear shape to the noises they make to communicate, seals and sea lions are amazing creatures with both shared features and many truly unique attributes.
