How deep do elephant seals dive?
Northern elephant seals can dive to depths of more than 5,000 feet and southern elephant seals to depths of nearly 7,000 feet.
During these impressively deep dives, elephant seals can hold their breath for up to two hours. They spend most of their time in the open ocean, only coming to shore twice a year to breed and molt, or shed their fur. Visiting areas along the California coast offer spectacular views of northern elephant seals during peak haul-out seasons and year-round.

Do humpback whales vocalize or “sing” the same song?
While the songs vocalized by humpback whales can change over the years, all males in a population sing the same song on a given year.
Their songs can last for up to 20 minutes and cover many octaves and include frequencies beyond the threshold of human hearing. When a humpback whale is singing, it floats suspended in the water, head down and relatively motionless.
How long do California sea lion pups stay with their mother?
California sea lion pups stay with their mother for about a year as they nurse and learn important survival skills, like how to swim and forage for food.
Sea lions return to their rookeries (or breeding beaches) in Southern and Central California each summer where females give birth to their 13- to 20-pound pups. This species breeds, births and weans simultaneously, which scientists call “synchronized reproduction.”
You can help the next animal in need when you adopt a past California sea lion patient.
