Sorry we missed #SharkWeek, it took us a little while to swim here.
The dwarf lantern shark is the smallest shark—it can fit in your hand—and has large, elongated eyes that allow it to see in almost complete darkness deep in the ocean.
Like other lantern sharks, the dwarf lantern shark has light-emitting organs called photophores along its belly and fins. They work as camouflage when the shark feeds in shallower water, as their bodies blend in with sunlight that filters into the ocean.
They're a mysterious species and have only been spotted a few times off the northern tip of South America. This specimen, from the Caribbean Sea off the coast of Colombia, is in our @smithsoniannmnh.
