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.

THE TRUTH IS...

what drives Mother Jones' team of 50-plus journalists. The truth is powerful, as evidenced by how hard those with something to hide, or profit to gain, seek to discredit it. The truth, stated boldly and reported meticulously, is what draws so many readers to Mother Jones.

And the truth is, going into the final 4 days of the year we still needed to raise $TK to hit our $350,000 goal and start 2021 on track. It's nerve-wracking, wondering if the big spike we normally see at the end of December is going to be another thing that doesn't go as planned in 2020, or worse, if, now that Donald Trump is set to leave the White House (for longer than a taxpayer-funded golf trip to a property he owns), folks might be pulling back from fighting for the truth and a democracy and think the hard work is done.

It's not, and if you can right now, please consider a year-end donation to support our team's fearless nonprofit journalism so we can close that big fundraising gap and finish the year strong, ready for all that's ahead in 2021. Whether you can give $5 or $500, it all matters in keeping us charging hard, and we'd be grateful.
