There are countless types of fish in the world. Some of these fish are beautiful, but some are ugly. So what I will introduce to you below is a very ugly fish. I don’t know what you think, but I think it doesn’t look good. This fish is the anglerfish! Some people also call it stutter fish, toad fish, etc.

The most important thing is that not only do they look ugly, but the entire life of male anglerfish is a tragic existence in the editor's opinion. Because their mating method is so unique! This kind of fish usually lives in tropical or subtropical oceans, and they can be found in the Atlantic, Indian and Pacific Oceans. There are hermaphroditic animals:

1. Atlantic scallop

An interesting Atlantic scallop grows along the coast of North America. The male scallop roams the bottom of the water until he finally finds a suitable mate. At this time, it lay on the back of the female flat shell. It doesn't take long for the male scallops to lose their genitals and completely transform into female scallops.

Afterwards, another male flat clam will fall on it and transform into a female. This mating process creates a tower-like chain of scallops, with females at the bottom and male scallops at the top, building the structure higher and higher. The only ones wandering around the bottom are male flat clams, while the female flat clams lie motionless on the bottom of the water all day long.

2． Barnacles

Mature barnacles are hermaphrodites - that is, each barnacle has the reproductive organs of both sexes.

Barnacles like to live in groups, as if they feel safe in this way, but overly dense colonies will cause the death of a large number of barnacle larvae. Sometimes barnacles avoid overcrowding by clinging to the hulls of ships, passing the crisis on to humans. To adapt to this upside-down lifestyle, barnacles have their ovaries on their heads.
