A Strange Love Story from the Deep

In a time full of romance and a royal wedding, BBC Earth looked toward the natural world to find out exactly which animal truly mates for life.

Weirdly enough, it took us to the dark zone of the ocean, more than 3,300 feet below the surface, to find the perfect couple. However, they were not only not what we expected, but were a total surprise to find at all! It was during the filming of the documentary series Blue Planet that the hairy angler was first discovered. Like many deep-sea fish, these creatures were new to science because of the great depths at which they live.

With a mouth full of fang-like teeth, a stomach that can expand to ingest prey twice its size, and a body covered in sensory antennae called neuromasts, you might be scared to learn that this is just the female! But never fear, the male is tenth the size of the female and much less frightening, at lease visually. Without a bright lure like the female, males ability to capture prey is nearly zero. Therefore the male takes on a more parasitic role.

With scarce food and mates, it’s essential to the survival of both male and female that the union is made permanent. When the two encounter each other in this inhospitable habitat, the male is quick to take the plunge. Latching onto her underside with his sharp teeth, the male will fuse with the female’s bloodstream where he will remain, providing sperm in return for essential nutrients.

However as time passes, not only will the male lose his eyes and all of his internal organs except his testes, but he could be joined by up to six other males! Watch BBC Earth executive producer Alastair Fothergill describe what he found weirdest about filming this amazing creature.

MORE HARD-HITTING JOURNALISM

In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones, a special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
