River otters attacked two swimmers in northern California — and one of them is an actor who appeared in an episode of “Succession,” news outlets reported. “I felt something on my back side and on my leg,” Crystal Finn told the San Francisco Chronicle. “I started looking around and yelling out and (the otters) popped up right in front of me. Then they dove down and started going at me again.” She told the outlet she was attacked while she was swimming in the Feather River near Plumas National Forest in July. … Megan Isadore, executive director of the River Otter Ecology Project, told The Mercury News that otter attacks are “very seldom, especially considering how many people are in the water, all over the country.” Otters don’t usually attack people, but it can happen when they’re protecting their young, McClatchy News previously reported.
