If you've ever been to Marineland or Sea World, you might be able to appreciate the enormous size of orca whales, or as most people know them, killer whales.

While on a 20th anniversary trip, a couple who was enjoying a deep sea dive was able to appreciate them on a whole different level.

Their names are Richard and Laura Howard and they were celebrating their 20th wedding anniversary in La Paz Mexico at Costa Baja Resort/Spa. They were diving near a friendly resident sea lion colony when their dive instructor saw a pod of orcas coming their way.  The instructor pulled them from the water, but the pod of around 20 whales decided that they weren't done playing just yet.
