A sick loggerhead swam to the dock of the only licensed veterinary facility in the world that just treats sea turtles, NBCMiami.com reported.
The 73-pound turtle arrived at the Florida Keys-based Turtle Hospital Sunday morning and wasn't immediately treated, because staff thought it may have just been lost.
But, the turtle stuck around for several hours, and was eventually treated for an bacterial infection by staff, NBCMiami.com reported.
Her shell was covered in barnacles and looked emancipated, the Los Angeles Times reported.
She will be released back into the wild after once she has recovered.
