Just look at these rescued baby cyborg seals
No, wait, no. The antennas are just for tracking the seals’ movement, so aquarium vets can make sure the babies — who’ve been receiving care and rehabilitation for months — are doing OK after their release. These transmitters don’t interfere with the pups’ quality of life at all — they’re weightless in the water, and they’ll fall off by next spring when the seals molt. And the seals look so cute with their little robot hats!
