First of all, thanks for what you have given me so far. (But don't let this be the end of it. Keep it coming as long as it can come.)

As for hair, I am giving them hair. I'm making their external anatomy like we expect mermaids to look. But almost all will cut their hair short using flint tools -- if I confirm, as I tentatively have learned, that flint can be shaped into a good razor.

Anyone have any idea how long one can swim spring-style and regular style before tiring out? (Again, for a typical well-trained swimmer.)
