Channel Islands National Park
California Spiny Lobster
 

Common Name
California Spiny Lobster

Scientific Name
Panulirus interruptus

Habitat
Kelp forests and surfgrass beds.

Additional Information
This species of spiny lobster is often encountered in rocky dens or in beds of surfgrass at relatively shallow depths. As highly prized targets for fishermen and divers, most California spiny lobsters do not live longer than 5-7 years before being caught. They have been known to achieve lengths of over 3 feet long and weighing 16 pounds. 

As predators, lobsters play a central role in maintaining the diversity of intertidal and subtidal communities. Predation on kelp-eating species such as sea urchins helps to maintain a balance in the kelp forest ecosystem, providing a more stable habitat for other species that rely on the kelp for food and shelter. The kelp forests of the Channel Islands offer an excellent rocky habitat for their pelagic larvae arriving with the converging currents from the south.

Did You Know?
Channel Islands National Park has more endangered species that only exist within this park than any other unit of the National Park Service. This means that survival of these plants and animals depends entirely on our ability to protect and restore the habitat of the five park islands.
