if all the 14 otter species were lined up in a race, who would cross the finish line first? imagine there's a land section and a water section (please consult the bean)
the smooth coated otter's smoothness probably means less air resistance and friction and they're fast predators underwater.
giant otters are bigger so they can go a further distance in one stride. but also they carry more weight
Eurasian otters and North American river otters are pretty athletic with how much they can migrate in a day, though i don't know if it would help them win a race
on the other hand sea otters probably wouldn't do well, being the slowest on land and essentially pure foragers so they have no reason to be super quick anyway
same with Aonyx which mainly chill and eat crabs.
