If you want loads of xp then you should punch it and kill everything that comes after you

I’m not entirely sure if this theory can be considered canon, but I think that the ammonite uses the pheromones as a psychological convincer to any random creature to defend it.
That’s just a theory, a GAME THEORY!!!

Don’t even think about hitting it. Just don’t. If you accidentally hit it, just swim away as fast as you can. I was out hunting for ammonites (I didn’t know what they did back then) on my basilosaurus. I saw one and hit it. I watched in horror as the whole ocean came swimming at me. I swam back to the surface, only to realise, a Tutsi was chasing me. It knocked me off my basilo and it tried to kill it. Luckily I had scuba gear. I got the gear on, whistled passive and put it to follow. The stupid tuso chased me around the whole map and now it is right next to my base. My basilo is stuck on the other side of the island. All because I hit an ammonite.

They have a built in distress call, so if you attack it'll yell for help and like Every Single Ocean Creature will run to the rescue.

To the ammonites rescue, not to yours.

It favorite food is force tame.

Basically the equivalent of the chicken in Skyrim, you hit it be ready for a big fight with the town

Ever met a cry baby?..This guy will wail if you hit it and will cover you in a type of pheromone gas....causing you to attract every dino, sea or land, to bite your butt. Prepare for war. You only need to survive 80sec.

You touch the spaghetti, le spaghetti will not forghetti that you toucha the important ammonetti

Attack them inside the mosa cave, it's smart....
