Aldrovandia affinis is a 55 centimeter long deep sea fish from the family of lizard eels (Halosauridae).

Appearance

These animals have a very narrow, cylindrically shaped body. They have large, smooth scales on their skin. The anal fin tapers towards the rear. The weight of the animals is about 6 kilograms. The pectoral fin is very narrow, elongated and tapered towards the rear. The color is brown-gray on the back and sides and darkens towards the belly. The back is black. The males have a very good sense of smell, which is probably used to find female conspecifics. There is no external difference between males and females.
