Channel Islands has five islands (San Miguel, Santa Rosa, Santa Cruz, Anacapa, and Santa Barbara) off the coast of southern California, near Los Angeles.
The entire park consists of 249,354 acres, half of which are under the ocean, and is home to a wide variety of nationally and internationally significant natural and cultural resources. Over 2,000 species of plants and animals can be found within the park.
However, only four mammals are endemic to the islands. One hundred and forty-five of these species are unique to the islands and found nowhere else in the world. Marine life ranges from microscopic plankton to the endangered blue whale, the largest animal to live on earth. Archeological and cultural resources span a period of more than 10,000 years.
