I was swimming back to base on my sarco and when I get back to base I turn it off I come back to find my sarco missing but not dead me 17 days later: let’s explore the ocean on our Meg next thing I see is a sarco swimming in the ocean killing mantas fortunately I brought sarco back to base and tail stunned them with my baryonyx
If you are planning on doing anything involving water prepare to despise these flat horrors. They can out swim you. They can swarm you. They can act friendly and once you turn your back eat your tame. Beware.
If caught in open water by a manta fight don't flee. If you have a spear or pike swim up as it gets close. This keeps you above it attack area and puts you in striking range. The manta is slower moving up and down in the water.
The manta is quite dangerous, as it's attacks can punch straight through armour, even flak. They are very fast and unless you have lots of oxygen and speed, you will not escape. Just poke your head underwater and look left and right before crossing the sea. It's like a road, but worse, because roads don't have angry stingrays, very large sharks and/or killer piranha
