You know, the seal thing. Waist-down, it's a bunch of seal. How would they cover that up? Would they need to?
I was sort of thinking, if necessary, a big - um...tail-sock? - with a drawstring around the top, or just keeping it uncovered. They apparently withstand very cold temperatures, so covering it up would be purely social obligation, if they're held to the same standards as the legged folk.
Thoughts?
EDIT: I know it says on the wiki page that there's really no difference in status between male and female Akvatari, but I'm assuming that applies only among Akvatari. If they were in, for some reason, an Inarta-dominated place, the same rules probably wouldn't apply.
