And it could go all the way, maybe the most massive animal in the zoo is the elephant of some kind. I don't know what it would be in kilograms but it would be fairly large. So maybe you can get up all the way to 3,000 kilograms or probably larger. Say 5,000 kilograms. I don't know what the mass of a very heavy elephant or a very massive elephant I should say actually is. Maybe something fun for you to look at. But any animal could have a mass anywhere in between here.
