I need to find a good description of fish cells--their size, shape, chromosomes, parts, functions, etc. It would be good to know precisely how they differ from human cells as well. I also need to know if fish mitosis is any different from human mitosis.
My main character is a mermaid, and a big theme is kind of a scientific approach to how her two halves are different. I'm still figuring out exactly how I'm going to use this information, but I think a lot of that depends on what information I find. I think she's going to have the ability to transform either into wholly one or wholly the other, and I want to know what will happen to her cells when that happens or how I could describe the change biologically.
I've googled various combinations of fish cell, fish cells, fish mitosis but haven't yet turned up with anything specific or non-expert friendly. Maybe there is an ichtyologist here!
