Didn’t know this about Tarrasques
Learned this on the internet a while back & thought I’d share it for those who haven’t seen/heard about it.
In evolution prey can adapt to have many things one of them is having spikes on their back to prevent predators from latching onto their backs or outright swallowing them whole.
This implies that there is something bigger than a Tarrasque & has chosen Tarrasques as their main prey.
