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.

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
