How big are anglerfish compared to humans?

Most anglerfish are considerably smaller than humans.

The European monkfish (Lophius piscatorius), a species of anglerfish, can grow up to 2 meters (6.6 feet) in length, longer than the average human, who typically stands about 1.7 meters (5.5 feet) tall. However, most anglerfish are about 30 centimeters (1 foot) long. Deep-sea anglerfish can grow up to 1.2 meters (4 feet) in length.

Female anglerfish are notably larger than males. In three anglerfish families, the males live as permanent parasites on their mates. The male attaches himself, by biting, to the body of the female. His mouth fuses with her skin, and their bloodstreams become connected. The male thereafter remains totally dependent on the female for nourishment, living as a permanent parasite.
