Quietly Clever

This deep‑sea creature looks like something from a horror movie: a huge mouth filled with sharp teeth, a glowing lure dangling from its head, and a body built to survive in the darkest parts of the ocean.

But here’s something even stranger than how it looks — the way anglerfish reproduce is one of the most extreme and fascinating behaviors in the entire animal kingdom.

These small seabirds see more daylight than any other creature on Earth. Arctic terns travel from their Arctic breeding grounds to Antarctic waters for the southern summer, then return north, experiencing two summers per year.

They use global wind patterns and celestial navigation, and often take a curved path rather than a direct line to take advantage of favorable conditions.
