SeaWorld San Diego announced plans for a new launched steel roller coaster called "Electric Eel" that will open in 2018. The roller coaster is similar in design to Tempesto at Busch Gardens Williamsburg. The coaster will reach speeds of up to 62 mph and a height of 150 feet making it SeaWorld San Diego's fastest and tallest coaster.

It is meant to be the second phase of the Ocean Explorer attraction, which has a strong educational component and is oriented more to families. It will also feature an eel aquarium.
Ocean Explorer will be located on the southeast side of the park where Animal Connections had been and before that, the old Clydesdale barn and pasture. Both Ocean Explorer and the coaster, which will be where Arctic Plaza now is, will occupy an area west of the Journey to Atlantis ride.
