Nope....definitely the North American River Otter. Been around a ton of those in a job in college. Be careful not to get too close. They can be VERY nasty critters despite looking so cute.
I still recall fishing the megabass on Fork years ago with a good friend...obviously trying to target good fat unders and out of no where an otter pops up 20 feet from us, jumps on a stump and proceeds to eat one of the fattest 15"ish fish I've ever seen.
Here's a great resource. https://tpwd.texas.gov/publications/pwdpubs/media/pwd_bk_k0700_0517.pdf
Look at pages 10 and 11 and you will see the minks and otters.
