A. Adult females grow to 10 feet in length and weigh 1,500 to 2,000 pounds. They can live to more than 20 years. Adult males are 15 - 18 feet long and can weigh more than 5,000 pounds. Males rarely live more than 15 year.

Q. Why do they throw sand on themselves?

A. Like some human behaviors, seals' "sand-flipping" probably has a number of explanations. Mainly, they do it to keep cool. The animals have a thick layer of blubber that warms them in 40- to 50-degree water. On land, even in overcast weather, elephant seals tend to overheat easily. The cool sand blocks the sun's rays and probably feels good. Seals may also flip sand if they feel threatened, agitated or even bored.

Q. How fast do they swim?

A. They are fast and agile enough to catch fish and squid. Swimming speed is estimated at 10-15 mph.

Q. Where do they go to feed?

A. Elephant seals are deep divers. They spend most of the year in the north Pacific, cruising at depths of 2,000 to 5,000 feet. They feed on deep-water octopus, squid, sharks, rays and fish.

Q. Why can't we get closer? They don't seem to be bothered by our presence.

A. Basically, for your own safety. Other pinnipeds like sea lions and harbor seals have a well-developed flight response. They get agitated and dash into the water when people or other animals come within 50 yards. Elephant seals seem to have a greater tolerance for the presence of strangers in their midst. This does not mean they are safe to approach. They are still wild animals. Elephant seals can and will respond aggressively to intrusive behavior when people or pets get too close. They can - and have - bitten people.
