Invasion of the (Beautiful) Bright Pink Sea Slugs

Kelly's nudibranch

“We’d never seen Hopkins’ rose nudibranchs in Humboldt until this year – now we’re seeing this,” tweeted local author and fish biologist M. Sid Kelly with the above photo.

The bright pink sea slugs appear to be moving northward in response to rising temperatures, says National Geographic. Normally, they aren’t found much north of San Francisco but, as Kelly’s photo shows…these times aren’t normal.
