Our photo of the day comes from sunny San Simeon, California.

I was looking for information on elephant seal vocalizations, given the song or cackle being expressed by the seal in the middle of this wonderful shot by photographer Rick Derevan. But I found some facts that were even more interesting.

• Elephant seals spend upwards of 80 percent of their lives in the ocean.
• They can hold their breath for 100+ minutes; longer than any other non-cetacean mammal.
• They dive on average between 980 to 1,970 feet beneath the ocean's surface.
• The deepest recorded dive of an elephant seal is 7,835 feet.

Isn't that impressive? No wonder they're singing and smiling.
