Humpback Anglerfish
{Melanocetus johnsoni}Tropical to temperate parts of all oceans
Max. size: 2.9 cm Total Length (male); 18.0 cm Total Length (female)
Depth: 0 – 2091 m (!!)
Males dwarfed and non-parasitic. Caught with plankton nets. Larvae are found primarily in upper 100 m. Oviparous, with planktonic larvae. Eggs are presumably contained in floating gelatinous rafts.
For me, this bizarre fish (the size of a tennis ball) is one of the most fascinating creatures in the deep sea. It has it all, it’s black, has big savage teeth, little nasty pin eyes, a big flabby stomach ready to fit in anything it can catch (irrelevant of size) and a rod lure off the top of its head with a glowing tip to coax in stupid prey. It doesn’t stop there: its flesh is watery, its bones are very light (barely coated by a thin layer of calcium carbonate) and it can barely swim (there’s not much of a tail). This animal just hangs mid-water waving its little lure and waiting to chomp. And this is only what the female looks like! The male is completely different. He’s very small and looks like a black jellybean with fins. He has no lure, has big eyes, huge nostrils and a fairly small mouth with curved hooked teeth. His body is made of strong red muscle for swimming long distances. Why the difference? She’s looking for food, he’s looking for her. She releases anglerfish-type perfumes into the water and he spends all his time swimming around looking and smelling for her. When he eventually finds her (in the dark), he latches on to her side (with his hooked teeth) and drinks her food-rich blood in return for producing the sperm she needs when it comes time to release her eggs. -
