Description

The ghostly seadevil is a deep-sea anglerfish (Linophrynidae) from the dark deep ocean. The female has a soft, nearly translucent whitish body and a lure on the head to attract prey in the dark. The male stays dwarfed and attaches permanently to the female, their tissues and blood circulation fusing; he thus becomes a parasitic 'partner' that only supplies sperm. It lives bathy- to mesopelagically. The species is harmless to humans.
