The absolute most powerfull sea dwelling animals, can one shot megs and destroy entire packs of piranhas. To tame, you will need at the VERY LEAST a level 200 quetz with loads and loads of points on weight, a quetz platform saddle, at least 45 cannons and a minimum of 300 cannon balls. Due to its long ranged tsunami attack, you will have to fire your cannons from very far away, make sure you never lose sight of the Coelacanth. The knock out part usually takes about 2-3 hours, the taming will take around 12-13. You will have to feed the coelacanth tames, 1 tamed giga sacrifice will increase its taming meter by 0.1%, and you will have to wait 10 minutes for the next sacrifice to come. Do this over and over and over and you have yourself a tame Coelacanth.

Pretty much unstoppable with an asc saddle. Can harvest metal, has very high weight and movement speed. They're very large and take wide turns. Can slither on land for short distances before taking damage due to suffocation. Sometimes can be seen flying through the air during lag. Can be passive tamed with phiomia eggs but be careful as they are very powerful.
