After receiving months of care at the Vancouver Aquarium Marine Mammal Rescue Center, seven rehabilitated Harbor Seal pups poked their noses out of their transport kennels and wiggled down to the waters of Howe Sound on the morning of November 20. Five of the rescued seal pups were outfitted with satellite-linked transmitters, which will provide valuable data to the aquarium’s veterinary team regarding the seal pups’ travel patterns and progress following their release.
In the water, the transmitters don’t weigh anything, and the seals don’t seem to be bothered by them at all! They aren’t invasive; no part of the animal has been punctured or any pain caused. They will fall off by the time the animals molt next spring, if not before. When the animals move, the antennas point backwards, and so they don’t affect the seals’ ability to swim.The transmitters are the result of decades of collaboration between veterinarians, biologists, engineers, and programmers.

emperor penguins, like other birds, have the capacity to fluff their feathers and insulate their bodies with a layer of air. but where most birds have rows of feathers with bare skin between them, emperors have a dense, uniform coat of feathers with tiny filaments at the base which allows them to release this air as lubricating microbubbles. this acts to reduce viscosity and cut drag, thus enabling the penguins to reach speeds of twenty seven feet a second and fly out of the water and over any potential waiting leopard seals.
