It is a very light fish: weights run from 0.5 kg to 2 kg with an average of 1.25 kg, and the maximum ranks 883rd of 1,059 documented fish. The price per kg is C$1,200, so an average-weight fish works out to exactly the listed average sale of C$1,500, which ranks 400th of 1,038. Base XP is 1,700.

The wiki quote describes "a giant tube worm that anchors near hydrothermal vents, harboring symbiotic bacteria to survive pitch-black depths."
