This is the second gray whale that’s been seen wandering in strange waters in the past few years. Another showed up in the Mediterranean in 2010. There’s a hopeful explanation for these appearances: According to the Guardian, some scientists are “speculating that this much-hunted great whale — reduced to near extinction in the 20th century — is regaining ancient migratory routes.”

Or there’s the less-hopeful explanation: It’s able to explore new places because climate change is heating up the oceans and messing with its northern food supply. We’re … we’re gonna go with the first one.
