It is unlawful to catch lobsters with your bare hands.

The Law Explained

To protect the state's most lucrative marine resource, lobsters can only be harvested using traditional, regulated traps. This law was implemented to prevent overfishing by divers and to ensure that undersized or egg-bearing females can be safely identified and returned to the ocean. Plus, sticking your bare hands into a rocky crevice to grab a heavily armored crustacean is generally a terrible idea anyway.
