[dnd] how potentially true is the joke that tarrasque are a prey species?

In the 5e artwork of the tarrasque, it’s eyes are on the side of its head and it has spikes on its backside. Speaking from evolution, these are traits primarily associated with prey animals. What’s the possibility there’s some CR 40 tarrasque eating horror?

The eyes to the side = prey, eyes in front = predator is not especially accurate. What it really represents is monocular vs binocular vision. Binocular vision is great for coordinating movement, judging speed and distance etc.... but with monocular vision you can see more things, so it's a trade-off. Sharks, for example, have eyes to the side, relying on other senses beyond vision.

In the case of a Tarrasque, When you can blunder into a city with your mouth open and get a meal, you don't really need super specific binocular vision. They're practically land-based filter feeders.
