TIL:
1. That the mesopelagic layer (200-1000m) deep is so full of "fish" that it messes with sonar.
2. That I should use "fish" because so little is known about them that there's no real helpful taxonomy (fish identification) guides
3. That scientists and governments want to exploit this little known area.
Can't help but feel that ends well. 😕
