Do you need a licence to have a pet crab?

In many places, you do not need a specific license to keep a pet crab, but regulations can vary by location and species. Some areas may have restrictions on certain types of crabs, especially if they are considered invasive or protected species. It's important to check local laws and regulations before acquiring a pet crab to ensure compliance. Additionally, proper care and habitat requirements should be researched to ensure the well-being of the crab.
