Unfortunately we do not know weather angler fish really attack people no one has ever approached one swimming in the sea. maybe if some divers went down in a submarine they could attach a human like dummy to the submarine and then find and approach an angler fish.

Anglerfish are generally the size of coffee mugs, about 1 foot long or less, although, some are up to a meter in length and up to 110 lbs. Females have characteristics the male does not. For one, females are larger and they lure in their prey in an especially unique way. Above the mouth, she has a long piece of dorsal spine extruding, ending in a small bulb of bioluminescent light. Anglerfish mate by the male latching his teeth into the female's backside. He slowly begins to fuse with the female. Soon the entire male is inside of the female except for the testicles. He then releases sperm into his mate.

Mostly the former, occasionally the latter

She doesn't make light for real her shiney and bright colors let you see that!

it is to attract other fish so that it can eat them.

Only PAINTED ANGLERFISH live in or near coral and sand (other species live in deep waters)

maybe

it must be extremely dark

it needs a very dark place to light it up and attract preys for it to eat...

the question is...how big are you?

yes they do, they sleep floating around.

The flavor of angler fish is compared to lobster in taste and texture.

When a young, free-swimming male angler encounters a female, he latches onto her with his sharp teeth. Over time, the male physically fuses with the female, connecting to her skin and bloodstream and losing his eyes and all his internal organs except the testes. A female will carry six or more males on her body.
