Polar bear cubs Neva and Amelia Gray made their public debut at The Maryland Zoo in Baltimore on Thursday. The pair are half-sisters who came from the Columbus Zoo and Aquarium back in October. “Neva is very independent and curious, and Amelia Gray is spunky and a bit particular. I think people will be very excited about them because they’re so playful,” said Erin Cantwell, mammal collection and conservation manager for the Zoo.
