And Charlie, the wolf eel, is no exception.
The shy, two-metre long creature with the toothy and fearsome underbite doesn't get out much — preferring dark crevices at a marine centre in Sidney, B.C., near Victoria.
So biologists at the Shaw Ocean Discovery Centre are sliding Charlie down the slippery slope toward romance.
They're shipping him off to the Vancouver Aquarium where two lovelorn female wolf eels, Betty and Veronica, could spark up some passion.
The aquarium will seal the eel deal by sending some of the anticipated offspring back to the Sidney facility. (CFAX)
