In San Francisco, at Pier 39, the well known sea lions are missing and there are not many left. Now you are lucky if you see one of them, and about a month ago, there was more than a thousand of them on the pier's floating platforms. So, what has happened to the sea lions?
The sea lions move up and down the coast a couple of times every year, but now they all are moving in great numbers at once. Some specialists think that they are following their food and instinct. Since they are following their food and instinct, there is no reason to panic.
Also the Marine Mammal Center is always on the lookout to find injured seals who need help. Once they get the seal all better, they will release it to the sea. If you are 14 years or older, you can volunteer at the Marine Mammal Center.
