River otters have much longer tails and a longer head than the sea otter. Sea otters have have large webbed hind flippers. When at the surface, river otters tend to swim on their bellies. Sea otters float on their back. River otters would be more likely to climb on a log or onshore to eat. Sea otters tend to eat their food in the water while floating on their backs, with the food on their stomach. River otters are on land frequently. Sea otters almost never leave the water. River otters tend to be all brown. Adult sea otters' heads lighten throughout their lifetime, becoming quite blond.
In addition to the above, Sea Otters often gather in large numbers called "rafts" while river otters are more solitary and are usually only seen in groups of 4 or less (mom and pups). River otters can be found in streams, rivers and coastal salt water areas.

Beavers and otters' basic biological differences are distinguished by their different taxonomical orders: Beavers belong to the order Rodentia and otters belong to the order Carnivora. The two animals also have very distinct visual differences: Where beavers are short, stocky and have wide, flat tails, otters are long, slender, and have long tapered tails. Beavers, as rodents, are herbivores, whereas otters are carnivores. Also, beavers live in lodges, whereas otters live in holts.
