To them, our oceans must look like Heaven. I found myself in a Grey's body in one of their loos. The Greys must be admired for the great strides they made in a relatively short time. They still appear to be egg laying though this is liable to change, as they favor the egg taking more time to develop inside the female. Males outnumber females by about 10 to 1.
Females are also dumpier and larger.
The male when successful, donates his testicles to the female, who is then fertilized for life. The location of the male testicles appears to be on the forehead as bumps or horns, which seems to be a daft place to keep them. The male after losing his testicles, dies in a state of religious ecstasy. Since coming out of the water, the males have learnt how to delay sexual union, and thus has changed their society from a matriarchal one to a male dominated society. This has also meant that the males have to do most of the work.
