I could be as faithful as a seahorse
And if you were a marine biologist
You'd know how tender that line was

Did you know that seahorses (at least many species of them) are monogamous- meaning that they are in an exclusive sexual relationship for the rest of their lives. According to the wikipedia article, they reinforce their relationships in the morning and at night time, and spend the rest of the day apart.  During this part of the day they hunt.    I guess that human couples can be like that when they are working from 9-5 - reinforcing their relationship before and after work and spending the rest of their day pursuing their own interests/survival methods.

Many birds are also monogamous, but many other animals are not.  The complication with animal monogamy is that you have to be able to distinguish your mate from others, which is apparently too easy of a task.  Monogamy is a big risk in the animal kingdom because you have bank all of your offspring production on the health and prosperity of your mate.  If you pick the wrong one, you offspring may be compromised.

I wonder about monogamy in humans.  Maybe we have a little bit more room for error, because if things don't work out we could just start all over again with someone else.  But I guess that isn't true monogamy is it?  I don't know.  I guess choosing a mate or getting married is banking a lot on one person, but I believe that the trust placed in one person is a really amazing thing.  I also think that the hard work in an exclusive life long relationship is what makes it so beautiful and valuable- because there are so many invested intricacies.

If I were a seahorse...
