"In fact, it shows common orca behaviours exhibited by both wild populations and those in human care as part of natural social interactions.
"During the interaction, one of the orcas sustained some minor and superficial abrasions that pose no serious health risk.
"Numerous scientific papers have been published about these behaviours among wild orcas.
"The papers include documented physical evidence in orcas that resulted from these same types of interactions in the open ocean."
This follows the news that an orca at the park had died as a result of an infection.
Nakai passed away last on August 5 and had reportedly been kept in a tank where he was bullied by other whales for 20 years.

PETA's Executive Vice President Tracy Reiman said: "In two days, one orca has died and another has been attacked by other frustrated, closely confined orcas, resulting in a serious injury.
"And young children were witnesses to the carnage."
In a statement, the organisation said marine parks cause orcas "extreme stress and frustration" and that keeping "incompatible animals" in tiny tanks means they have nowhere to escape conflicts.
