What was your HP at (not seamoth, but you). Also, did your entire screen go all white and whirly?

Considering your Seamoth lived but you died, it was either:

1. A Reaper that killed you through a bug.

2. A Warper, which can kill you through your vehicle (you can be in the Seamoth but still get damaged). This would explain why it made a weird noise and was away from any landmark you recognized.

3. A Crabsquid that EMPed you, which might have caused you to exit vehicle and collide with yourself.

Have you compared the sound you heard with sounds in-game? It might be the easiest way of finding your killer.
