Lobstermen are busy hauling in the ocean crustaceans that will fill the delicious lobster rolls we crave in the summer.

Clawed lobsters of the northeast walk along the ocean floor in depths from 20 to 100 feet. Sometimes they'll walk right into traps or "pots," preferably baited with herring, through funnel-shaped openings that prevent the creature from escaping. This method of lobstering has been used for more than 200 years, since the trap was invented in 1808 by Ebenezer Thorndike in nearby Swampscott.

Brightly colored buoys mark the spot where the trapper can retrieve the day's catch. If the lobster is an acceptable size as set forth by state regulations, it's back to shore to meet up with a kettle of boiling water, butter, bun, and a big bib!
