Spiny lobsters lack enlarged claws and are well-protected by sharp forward-pointing spines.  Large species are no longer common due to heavy fishing pressure and disregard for local laws.  Minimum carapace length is 3.25 inches.  Illegal to harvest from May through August, spearing and taking of females with eggs prohibited.
