Seals have tricked me before with their one-flipper pose. A month ago, I saw a seal hold this one-flipper pose for much longer than ten minutes. I began to worry that it was injured. Only after I had called the DOC Hot Line and was speaking to someone there, did it roll over and clap its flippers together as if pleased by the joke.

Seal - thermal regulating |
I thought that it must have been having a rest, but a friend explained that what the seal is doing is called thermal regulating. Holding a flipper out of the water helps it either cool down or warm up, depending on the sun and the wind.
