UPDATE - Turns out the seal is a girl.
This is the email I got from Jay at the Marine Mammal Stranding Center:
Thanks for the photos and the calls about the seal. While there were no obvious issues with her, we did pick her up because she was very lethargic. It may be a few days before we know exactly what all of her issues are. Feel free to check in with us next week to see how she is doing. You can also check our website every few days for updates and adoption info for her as well.
Thank you again,
