creatures that dwell deeply under ocean's surface are notoriously alluring, and the lantern shark one of them

this small shark has fluorescent markings flank both sides of its body, they called lateral photophores 

The markings glowing vibrantly and mysteriously in deep-waters, deep-sea researchers have been trying to understand why these markings exist.
