The phrase refers to the offering of Gecarcinus quadratus, a species of land crab known for its distinctive coloration reminiscent of Halloween imagery. These crabs exhibit a striking appearance with a dark body, bright orange legs, and purple claws, making them visually appealing to enthusiasts.
The availability of these crabs caters to the niche market of exotic pet keeping and aquarium hobbyists. Keeping these crustaceans can provide individuals with the opportunity to observe unique behaviors and contribute to a greater understanding of this species’ needs in a captive environment.
