General information

The California Spiny Lobster, Panulirus interruptus, is a species of spiny lobster found in the eastern Pacific Ocean. Unlike their clawed cousins, spiny lobsters are characterized by their long, thick antennae and lack of large pinching claws. Their exoskeleton is adorned with sharp spines for protection, and they exhibit a striking coloration of spots and stripes that can vary from reddish-brown to a more muted olive green.

Care

In the aquarium, California Spiny Lobsters require a large tank with plenty of hiding places and room to roam. They are nocturnal and tend to be more active at night. It's important to provide a diet that includes meaty foods such as shrimp, fish, and mollusk flesh. They can grow quite large, so it's essential to consider their full adult size when planning your tank.

Reproduction

In the wild, California Spiny Lobsters migrate in large groups to spawn. In captivity, breeding is less common, but with the right conditions, it can be achieved. They have a complex life cycle with several larval stages before reaching maturity.

Symbiosis

While not known for specific symbiotic relationships like clownfish and anemones, spiny lobsters do play a role in their ecosystem by scavenging and helping to keep the ocean floor clean of detritus.

Habitat

California Spiny Lobsters are typically found in rocky reefs and kelp forests where they can hide from predators. They range from Monterey Bay, California, to the Gulf of Tehuantepec, Mexico, and are particularly abundant around the Channel Islands.
