The spiny lobster, belonging to the family Palinuridae, is a type of crustacean found in warm coastal waters around the world. Unlike true lobsters, spiny lobsters lack large claws and have long, spiny antennae. They typically have a hard exoskeleton that provides protection and can vary in color, often featuring shades of brown, green, or blue. Spiny lobsters are primarily nocturnal and are known for their ability to hide in crevices and under rocks during the day. They are social creatures, often found in groups, and are an important species in both commercial and recreational fishing, contributing significantly to the seafood industry.
