Peter Kavanagh, age 10, of Ottawa, Ontario, Canada, for his question:

Is it true that some fishes have lights?

Yes, this amazing report is quite true. If you guessed that these strange fishes have lights because they live in the dart:, you are correct. They live a mile or more down in the deep ocean, where the light of day never penetrates. Their watery world is cold and blacker than blackest midnight. And these deep ocean dwellers are just about the weirdest looking creatures that live on our planet. :lost of them have huge heads, bulging eyes and enormous jaws crammed with menacing teeth. Many have long skinny tails or thin trailing fins.

Most of these smallish fishes of the deep have built in lights    and some of these lighting systems are downright fantastic. They glow in vivid blues and reds, greens and white. Several species wear rows of these illuminated buttons along their spines. Others wear razzle dazzle groups of lights on their heads or sides. Their lights make the deep ocean dwellers visible and recognizable to each other.
