The difference between marten and otter?

[Petlover500]

So, I was trying to look up the difference from marten and otter, but failed to find a very clear answer.
From what I read, it is the fur pattern that separates a marten from an otter- a marten has a larger white portion on his chin that is in the shape of a triangle, and the insides of his legs are white too, while an otter has no white on the inside of his legs and no white on his chin?
Pictures seperating the two would be amazing... I could not find any clear pictures
:hmm: :shrug: :thinking:

A marten is a chinchilla (called silver marten) or sable (called sable marten) version of otter so they have white or cream instead of brown in their markings
