So, they added in stable now with Cuddle Fish update.

Head down to Lost River, and look for the giant leviathan skull that has the alien tech all around it (not the skull at the end of the skeleton, the other massive skull that has alien tech tentacles shooting light on it).

When facing the skull, if you head up and left you'll see an alien door that's locked with an orange key.

In there you'll find a cuddle fish egg.

This is all above 900m, so you can take the seamoth down there to retrieve it if you have a mk3 pressure module and can craft orange alien artifacts.
