The cat and the tuna are ancient predator and prey.

Back on the plains before humans, cats used to prey on tuna, cutting out and eating the tastiest and slowest from the school.

Not just plains tuna, but desert tuna.

The tuna evolved eventually into buffalo but it took a long time.

They first established a beachhead and began hunting large cats by constructing a series of breathing apparatuses out of kelp.

It didn't always go that way - I understand that tuna developed a breathing apparatus with kelp, they were able to trap certain amounts of oxygen. Not going on land for days at a time, an hour, hour 45. Enough time to establish a beachhead and aggressively hunt cats and their family.
