Lynn Kramer, the zoo's vice president of animal operations and welfare, says five lions in total are in the exhibit and have never appeared to endanger each other before. The three lions in question have been in the same exhibit for three years, Mr. Kramer said.
“I would have to think something caused the males to react that they don't normally see every day,” he told The Dallas Morning News. “Lions can be aggressive, but they don't kill each other.”
The zoo says the aggressive lions were not euthanized.
