What’s that in its head?
Family: Spook Fish
We humans often wish we could know exactly what goes on in other people’s heads. But this isn’t just a figure of speech when it comes to spook fish: its head is see-through! But why? This fish lives deep down in the ocean, where there’s hardly any light. It can also rotate its eyes into its transparent head, letting it look in all directions to find the smallest bit of light. After all, it’s better than groping around in the dark.
