Actual explanation: these squid are transparent normally, but can turn on a dark pigmentation when that is a more effective camouflage. Being transparent works quite well most of the time, but if the predator has its own light source (as several deep-sea predators do) then their transparent state becomes a problem, because it's relatively reflective compared to the water around them. In this situation, turning on the dark pigment helps them blend in with the dark water better.

What about their blood and organs and anything it had recently eaten? How does 100% of it turn transparent

the scientists have inadvertently discovered that this squid is also a witch

Impossible. It's under water, which means that it weighs more than a duck.

then this suggests that our knowledge of ducks is also in error

Not even humans have yet figured out how to reproduce a Colorchecker Passport.
