The male sea lion was first spotted on Highway 4, between Port Alberni and Ucluelet, on Dec. 4, and researchers theorized it must have followed the Kennedy River from the ocean to nearby Kennedy Lake.

"It's really dangerous," Paul Cottrell with the Department of Fisheries and Oceans Canada told CTV News. "You can imagine a 300-pound dark animal on a highway. And the animal has been coming out of the water at nighttime on Friday and Saturday." The sea lion was last seen in the area on Saturday, and a Vancouver Aquarium Marine Mammal Rescue Society team attempted unsuccessfully to locate and sedate the animal on Sunday. Martin Haulena, executive director and head veterinarian at VAMMRS, said he is concerned the sea lion might be suffering from a neurological problem. "Ideally, what I'd like to do is bring this animal back to the rescue facility and have a good look at him. I'm not convinced 100% that he is perfectly normal," Haulena told The Chilliwack Progress. "But if we can't get him back safely here, relocation is still a possibility. I'll leave that up to DFO."

There's likely not a lot of prey for the animal in Kennedy Lake," Cottrell said.
