About time, really. V:
This takes so much precedence over the old, very, very outdated sheet it's not even funny. Less pure dolphin, more of my own ideas. There is much more to 'em in terms of tech, culture, etcetera, but all that is still a work in progress, while this here - the general design and anatomy - is done. Also shows the usual range of heights for them. This does not include extremes, nor gigantism or dwarfism.
They also have pets now. The fuzzy otter-like crittera are not unlike cats. The Seal-ish one's suspiciously doggo-like but eat feesh. Pet 'em lots.
