comment What limits the size of fish compared to marine mammals?
That is very interesting and definitely a possible reason. I was not aware of the fact that extracting oxygen from water was such an energy drain for fish. This might mean that larger fish species did exist at some point when the atmosphere (and the oceans) had a higher oxygen level.

Luckily they can't. However, keeping the question above in mind, I don't think that this is of any relevance.

That is the reason I put "direct" between parentheses. Strictly speaking, prions do not make use of DNA to propagate. However, as you indicate, there is definitely room for debate.

What is considered alive? This is a good question. I think it is safe to define something as alive when it is (1) capable of sustaining and replicating itself and (2) able to interact with its environment.
