Thought those were little hearts at first only to realize...

I've always wondered at how the hell the female's body figures out how to route the sperm from wherever the hell the male decided to embed itself in their body to its eggs.

At least it's somewhat less absurd than that species of beetle or cockroach or something that just violently stabs it's pointy dick right through the female's abdomen, and hopefully the sperm somehow manages to hit the right spot, and the female doesn't die of the physical trauma or resulting infection before the females manages to lay the eggs.

@The_Catman I believe the anglerfish has external fertilization outside the body. So the males that are near egg laying orifice are more likely to father offspring. As such evolution has made them more likely to end up on the underside near it. But occasionally they attach in other places.

Lucky. I wish I got to be in that female dominated sexy specie

... They become a "spermproducing parasite"

o.0

I'm curious as to the evolutionary process that led to this development...

@Doodledibob My guess is that the low population density (individuals per square mile) & solitary nature coupled with the timeless, featureless nature of their environment are what drove this.

If a species has high population density or is fairly social, then when a female is ready to reproduce there are likely a few males around that can fertilize her. And if the species is low population and solitary they can they can use the changing seasons or time of day to coordinate their mating periods or scent mark landmarks to let others know they are the are and are fertile.

So what likely happened is that the males that stayed near the female, reproduced more than the males that were nomadic & relied on chance encounters because they were more likely to be near a female when she was ready to reproduce. So that right there would force pair bonding.

Next comes the shrinking of the males. Sperm is cheap and eggs are expensive in terms of calories. So every calorie that is utilized by the female in the pair bond results in more offspring for the couple than if it went to male. So males that are smaller have more offspring. Eventually the males probably got so small they probably started to live off the female's dead scales, scraps, parasites, and waste.

Then one day a male bit a little too deep when cleaning his female and started living off her blood. From there the diminishing of organs kicks in. Remember the golden rule for him, the more calories that he let's the female have, the more offspring he has. The less digestion the male does to the blood, the more calories and oxygen it provides to him. So there goes the digestive system and gills. And the blood was already the perfect medium to support him, so out goes the liver and several glands. He is no longer having to find his own food, so out goes the brain, bones, muscles and most of the skin. When all is done he is has deferred all of the calories he can to the female except for those necessary for him to reproduce.

@Aray_dash Your avatar picture fits that comment so well XD

oh I adore this one! Anglerfish is one of my fav creatures simply because their wild breeding method. You really made them come to (human-ish) life

And that is why I know I was originally meant to be a male anglerfish!

That's not an anglerfish, that's just its light making us all think we're seeing a pretty lady.
