Reaction to the horror at SeaWorld has run the exhausted gamut.

“Kill. The. Fish.” was one talk-radio host’s suggestion. “Save the whale” has been the sentiment of animal lovers, including the victim’s family.

Mostly people want to know: What was the whale thinking? Why did he do it? The truth is probably less interesting than our anthropomorphizing minds might wish. Most likely, Tilikum the Killer Whale simply had a “seeing red” moment. He lost control – and then it was over.

Sometimes the Discovery Channel eats Disney.

This, more or less, is the considered opinion of a former whale trainer and scientist, Heidi Harley, who happens to be my cousin. Naturally, upon hearing the news of Tilikum, I called Heidi, a former whale trainer and Orca-rider at Miami’s Seaquarium. She now teaches comparative cognitive psychology at New College in Sarasota, Fla.

Heidi is an intractable scientist, resistant to even a cousin’s urging to summarize and opine. She does, however, offer a few objective observations that are relevant and interesting.

First, she notes that the whale who mauled and drowned trainer Dawn Brancheau had a history of aggression and probably should not interact with humans in the future except under extremely controlled circumstances. That is obvious in retrospect and doubtless will be the case henceforth. But toward theories of human-like motives (premeditation, for example, as one “expert” suggested), she is highly skeptical.

The idea that a whale could premeditate presupposes what science cannot prove, says Heidi. Sea mammals have many amazing characteristics, including the ability to communicate within species and to form long-term relation- ships. But there is no evidence that they can imagine a different world and act to produce that alternative reality, as humans routinely do.

What is known is that so few such incidents occur.

“There’s something remarkably restrained about the animals. That this happened is a tragedy,” says Heidi.

Even when whales and dolphins give signals of aggression, slapping their tails or nodding heads, they are really demonstrating their self-control. When they “see red,” as humans often do (crimes of passion), they simply lose it. No plan, no strategy, just a very bad moment.

The question that inevitably arises in these rare instances is, should whales be in captivity and exploited as circus acts? That, ultimately, is a values question. Should we have zoos? Eat meat? Drive SUVs?

Whales born and raised in captivity can’t safely be delivered to the open seas. Meanwhile, arguments can be made that interaction between pampered animals and humans ultimately raises awareness that leads to protection. Not long ago, commercial fishermen used to shoot killer whales on sight.

But if we want to understand more about what causes a massive male predator to destroy a human being in a sunny Orlando pool, we may have to protect whales a little less and make them more available to researchers.

Or else leave them to their own devices, possibly elsewhere.
