Which of these deep-sea creatures actually has a transparent head that allows it to look through its own skull to hunt prey?
Correct
The Barreleye fish is the weird winner here. It has a fluid-filled, see-through dome on its head, letting it peer directly through its own noggin to spot prey swimming above it. The Giant Oarfish is basically a super long, shiny sea ribbon that likes to show off its size rather than play hide-and-seek with transparent parts. The Vampire Squid is purely a dramatic name-fake, as it eats marine snow (basically deep-sea leftovers) and definitely does not have a glass dome for a forehead. Lastly, the Frilled Shark looks like an ancient fossil that decided to go for a swim, but it sticks to a more traditional, non-transparent skull design.
