When I first encountered one, I was scared out of my mind. I just got my seamoth and wanted to explore near the Aurora. My innoncent eyes have not seen many aggressive creatures- really one 1 medium sized one. I went at night and I thought I would be safe out in the open. I see a creature that is pretty long in the distance. It looked scary from its shadow so I turn away to go back to base. The mother f*cker grabs me, starts swaying me around, screams at my face, and continues to haunt me for the next 20+ seconds- which is a long time! It destroys my seamoth while throwing me a few meters out. I swim back to the safe shallows.
I was going to aurora and i was to scared to drive so i had my brother drive the seamoth. He didn't know the entrance was in the front and kept going below 100 meters,luckily, i didn't encounter one, but i could hear it. My brother also dropped me off at the engine of the ship and i was too scared to drive back to my pod because i thought one would follow me, so i quit the game without saving it and left. I still want them to stay.
(spoiler alert) I saw one while going to the tower for sunbeam to pick me up and it was in the surface. I don't think it saw me, but that caused me to swim all the way back to my pod and not witness sun beam exploding by a tower. At least it didn't get exploded by a reaper. I want them to stay but please, keep them down deep below 100 meters.
they should stay because the crash zone and other places were they are all have important blue prints or other things and it wouldent be fun having a safe game were theres no threats stopping you from progressing the game.
The first time I saw one of these was when I was trying to fix the prop core. It stole my seamoth, and ran. I was still so scared that I resorted to building a massive pipe from lifepod 5 to the aurora. The core exploded anyway. Even so, please keep these things, if only so I can kill one some day.
