From sea otters to harbor seals you will find it all at Marine Mammal Mania at the Seattle Aquarium.
"It's three weekends of marine mammal fun. We'll be meeting all sorts of field biologists and you can even go on our website and guess the weights of all of our marine mammals," said Traci Belting, curator of birds and mammals for the Seattle Aquarium.
One of the animals that will be featured is a northern fur seal, these seals have 300,000 hairs per square inch to keep them warm in the water.
"This type of seal can be hundreds of miles from land and stay at sea for almost a year at a time," said Belting. There are only 10 northern fur seals in zoos and aquariums across the United States.
Marine Mammal Mania goes Fridays, Saturdays and Sundays from April 6 through April 22.
