A couple doodles of my fish-people from my rough concepts here -> http://www.furaffinity.net/view/22822063/ <-

A young adult male and female, as well as a very young child, gender undetermined. They are a short and stout race, as previously mentioned, similar to dwarves if dwarves were dolphin-people who lived on islands and survived on fishing rather than mining! They are generally on the chubbier side, and if they were to be skinny, they'd probably be sick tbh, and the others would treat them as if they were of very frail health. Their height gets to about five foot at the absolute tallest, averaging at about 3.5-4 feet in height.

They are similar to frogs in that they are born very fish-like, with only small nubs for limbs which develop as they grow, until they can learn to walk on land.
