How long is a fully grown dwarf lanternshark, the world’s smallest shark?
Found in the waters off the coast of Colombia and Venezuela is a dogfish shark that grows to be just seven inches long. The dwarf lanternshark, the smallest in the world, is tinier than a human hand and eats prey that is even smaller. As its name suggests, the lanternshark can create its own bioluminescent light, which it emits from its belly and fins to attract prey.
The correct answer is 7 inches.
