I'm at work and havent actually finished reading yet, but this is pretty wild. The universe is just amazing.

What with those and fish who change sex (wrass and others), including reproductive organs, who knows what they will get up to next! Probably breathe air and climb out of the water.
Oops, the climbing perch does that already, just like our distant ancestors.
Truly fascinating.
Dave we have a species of catfish in Florida that can and do get out of the water and walk on land. They do not walk as we would define the process. They use the spines on their pectoral fins to drag themselves along. That species and its brethren have rigid bones in their fins that probably act as a defense mechanism as well as to provide a means of mobility.. On certain salt water cats there is a mild venom in the bony part of the fin. Painful to humans.
Perhaps our marine biologists have some explanation for the fishes need to move across dry land from one body of water to another. I have my own notion: they are atheist fishes who are trying to provide evidence of the validity of the Darwinian postulates.

Yes, there are also the mud-skippers that build territorial "compunds" on the surface of the mud, feeding, fighting and mating there.
I was being a bit flippant, there are all kinds of seemingly unfishy things that fish do.

Thanks for posting that,
Pasta Chick. I didn't know that androgenesis was even possible, let alone in vertebrates.
