The darker depths of the sea contain many enigmatic mysteries that come in the form of aquatic life.
Studies on the deep-sea dragonfish has been discovered to contain invisible teeth applied to their survival in the wild. The elusive fish can be found in depths of about 500m.
The technological breakthrough was achieved using transmission electron microscopy of one dragonfish species.
According to latest findings by researchers from the university of California, the odd-looking fish uses its hidden teeth to catch unsuspecting teeth.
This is not the first instance of an animal with hidden teeth, but the study may provide better understanding of the interactions between teeth with light.
