The pygmy lanternshark is the smallest shark in the world. It lives in the deep waters of the Caribbean Sea, can glow, and grows no larger than 21 centimeters.
The pygmy lanternshark differs from other sharks by its tiny size and special glow. It helps maintain balance in deep-sea food chains by eating small animals.
Immature form that undergoes metamorphosis before adulthood.
