I had to write some about this when and not to mention – show a few pics of this remarkable fish.

The angry-looking deep sea anglerfish has a right to be cranky. It is quite possibly the ugliest animal on the planet, and it lives in what is easily Earth’s most inhospitable habitat: the lonely, lightless bottom of the sea.

The angler fish has developed a quite special form for commitment. The frase “till death do us part” gives a whole new meaning when you read about this extraordinary creature.

Some anglerfishes employ an unusual mating method. Because individuals are presumably locally rare and encounters doubly so, finding a mate is problematic. When scientists first started capturing ceratioid anglerfish, they noticed that all of the specimens were females. These individuals were a few inches in size and almost all of them had what appeared to be parasites attached to them. It turned out that these “parasites” were the remains of male ceratioids.

The male never gets any bigger than a few cm long and as very young, he developes very sharp and hook formed teeths. With these he attach himself to a female. He releases an enzyme that digests the skin of his mouth and her body, fusing the pair down to the blood-vessel level. The male then becomes nothing more than a pair of gonads, which releases sperm in response to hormones in the female’s bloodstream indicating egg release. This extreme sexual dimorphism ensures that, when the female is ready to spawn, she has a mate immediately available.
The male is simply reduced to a sperm producing attachment wich the female uses when she has the need.

Female Dominance? You bet it is.
