Some people say hermit crabs don't DO enough (they should meet my cats-they lay around more than my crabs). There are periods of time I am frustrated by the fact that I don't see them for a while.
However, I think that makes them great pets because they can provide an important life lesson, PATIENCE! We are all so used to getting just want we want when he want it, hermits crabs teach us that not having instant gratification is OK.
Also, it increases one's powers of observation, I feel observation and noticing small details, like pre-molt signs is something else crabs teach us.
From a learning scientific standpoint, they are fascinating as well.
And let's not forget, THEY ARE SO DARN CUTE! And when they're active they provide all kinds of good, wholesome family entertainment.
I was trying to think of parent friendly reasons that you could clinch the deal with.
