Life on earth is truly stranger than anything we’ve imagined. Science continually finds more evidence of this. Just one example? Fish in waters devoid of any natural light equipped with light-giving powers of their own.
How do these fish manage to produce light from their own bodies? Through a mix of two chemicals. One is called, ominously enough, luciferin. This chemical creates the light. The second chemical, luciferase, spurs the reaction that, along with oxygen, creates the light. Deep-sea creatures use this light to not only find their way, but also to communicate with other fish and trap their prey.
What I love about science and nature is that there are so many twists and turns in the evolution of life, ones we are still discovering, that rival the wildest creatures dreamed up in our imaginations.
