That’s whale fall — what happens when an enormous cetacean corpse hits the ocean floor — not whale fail — what happens when Twitter breaks.

You see, when the carcass lands on the bottom of the sea, a whole host of unpleasant critters come out to eat it in a process that can take months — or even years if the whale lands in deep, deep water. Among those critters are members of the genus Osedax, bone-eating worms related to tubeworms or those guys you see hanging out by thermal vents…if you happen to go past a lot of thermal vents, that is.

Robert Vrijenhoek of the Monterey Bay Aquarium Research Institute first discovered these little red bone-munching guys while out in the ROV Tiburon, which is a vehicle with just an awesome name. Their press release provides a great read. (And, doesn’t he look like something out of central casting for ocean explorer?)

Sure, unless your diet has really slipped and you’ve reached blue whale proportions, you don’t have much to worry about from these critters (aside from the fact that you’d be dead and lacking cares, in general). But the fact that these guys are down there waiting…just waiting…gives me the creeps.

Even creepier is that all those little red wigglers you see in the picture above are all females. They’re not hermaphrodites. Oh no, that would be normal in comparison. All of these worms are actually giant masters over their microscopic male concubines. That’s right, mini sex slaves. Invertebrates with a dwarf fetish.

But, according to Vrijenhoek, “That was not the end of the weirdness. In looking at the worms under a microscope, we discovered that every one of them was a female. We didn’t find any males until I got another call from Greg Rouse. He said, ‘Bob, it’s worse than you think.’ I said, ‘What now, Greg?’ He said ‘There really are males, but they are microscopic. They are dwarfs!’”

Sure enough, living within the tube that enclosed each female were 30 to 100 microscopic male worms, each only about a millimeter long. Not only that, but the male worms were still in a larval stage of development. They were making sperm in one part of their bodies, while other parts of the bodies still contained the yolk droplets. As Vrijenhoek put it, “These males don’t feed. A male lives its entire life off the yolk that was provisioned by the egg from which it hatched. This is one of the few cases in the animal world where sexually reproducing individuals are barely more developed than eggs. It’s weird.”
