Beachcombing along the Connecticut coast can be a fun and healthy educational activity for families eager to get out outdoors while the COVID-19 virus keeps children home from school.Among the many publications available from its website, Connecticut Sea Grant is calling attention to Living Treasures: The Plants and Animals of Long Island Sound, and a series of three pamphlets about seaweeds, shells and beach plants that families can use for easy beach activities. Families are urged to send photos from their outings that will be posted on the Connecticut Sea Grant website.
