They tend more often to be epidemics than pandemics since most nonhuman primates lack the ability to cross the ocean. That said, here ya go: http://www.bbc.com/earth/story/20150327-ten-scary-diseases-of-animals

I agree (about the first part of the sentence, the second claim I've yet no evidence of). And I may add that I have met a few individuals that I might generally consider "stupid" that nonetheless have from time to time done something rather smart. There are great examples on this forum. People that probably are intelligent or "smart" in some other context fail to follow the forum rules, resulting in miserable content and closed threads.That could maybe labeled as "stupid". Even in a well-defined context an observed behaviour may be labeled stupid or smart, depending on the observer and what the observer knows. (Maybe this post as well shows that Phi is correct. It may be considered stupid behaviour to have a few nice craft beers and then try to post something in the philosophy section ...)

In my experience, smart and stupid describe behavior, not individuals (of any species). I don't think you can say a person is smart about everything, or stupid about everything. I might think of myself as a generally smart person, but I know I have the capacity to do some very stupid things nonetheless. Determining some working parameters for general smartness or stupidity seems pointless and subjective. It's much easier to judge behavior. "You're not a stupid person, but you do some stupid things." Now you have to determine what's stupid and what's smart, and you have to consider context.

Using a quick wikipedia search, I find that there are 5,450 species of mammals. https://en.wikipedia.org/wiki/Mammal of which 130 are marine, living or recently extinct https://en.wikipedia.org/wiki/List_of_marine_mammal_species. sure 130 could be considered 'many'. Now if you meant aquatic, then yes there are many animals that are (semi)aquatic How do you determine, 'most viral infections'... there are many many more bacteria than animals, so are we just counting numbers, or do you mean that there are more bacteriophages than regular viruses (if so, please post a source, I'm interested). How can a virus be 'marine', as Studiot mentioned? Or do you mean that viruses can persist within the ocean. That seems to be true; https://www.tandfonline.com/doi/full/10.1080/19475721003743843 link to marine specific viruses (bacteriophages specifically I think): https://www.biorxiv.org/content/10.1101/025544v1 https://en.wikipedia.org/wiki/Marine_bacteriophage

Today I learned that skills improved by participating here on scienceforums can, at least in some minor way, be helpful in the current virus situation. I joined a local initiative where students studying from home can ask about math and physics. Debating science here has made me more confident regarding mainstream science and how to respond with useful hints (instead of solutions) to homework questions.

I don't need to derive geodesic equations: I can simply state that the anti-photon engages the next two negative spacetime events thereby possibly changing its direction of motion. We associate numbers to negative events simply by stating: CB("Name of Coordinate System", -ngx_1 - mgx_2 - lgx_3 - kgx_4), where x_i element of unit vectors on R^4, n, m, l, k element of N, g element of R. From Figure 1.5 we see that an electron may emit a photon or an anti-photon (the two electric charge circles). To create a photon from an electron we need: an operator called a copier, a charge copier and a charge transport operator. We work in the reference frame of the Centre of Mass of the electron. The copier must copy the circle of S_2 and the Riemann Sphere of S_2 itself. Then the carge copier must make 2 copies of the charges on S_2, then the charge transporter must move two of the copies as follows: move the copied charge from (1 - idelta) to (-delta - i) and the one from (-1 - idelta) to (delta -i). Then the other copy of the right sided charge must move to (1 - i(delta + lambda)) and on the left to (- 1 - i(delta - lambda), with lambda chosen by the observer so that the line between the left and right charges is prependicular to the momentum direction. Since lambda > 0 we have the momentum not precisely in the "up" direction. The same orientation as a reference photon. They are seen as phase shifted photons. Space is made of numbers. I reject the strong force, I think we can do without it. See anti-photons as phase shifted photons going back in time. What is not compatible with the standard model?

I can't believe stars are other suns because I have seen a star stop shining in front of my eyes.

Sorry ... no. READ THE OP. But I fully understand your typical last-word SMARTY PANTS mentality, which is TYPICAL of science and skeptic forums. But I gave you a an UPVOTE anyway b/c of your BBC link. Now where is my DOWNVOTE? Four reasons: (1) More surface area of Earth is H2O than air. And most lifeforms are in that environment. DUH!!!!!!!!!! (2) Viruses don't survive long in air, esp. under sunlight. DUH!!!!!!!!!!! (3) bacteriophages, bacteriophages, bacteriophages!! https://en.wikipedia.org/wiki/Marine_bacteriophage "Viruses have an estimated abundance of 10^30 in the ocean, or between 1 and 100,000x10^6 per millilitre." (4) Because I said so.
