This humongous lobster battered the competition!

The 20-pound monstrosity was the biggest caught in the Bay of Fundy in Canada this year, according to a Long Island seafood restaurant, which brought back the monster catch Tuesday.

“Most of those guys are between 3 and 6 pounds. This one must be the grandfather!” said Steve Jordan, the owner of Jordan’s Lobster Farm in Island Park.

With claws large enough to snap off someone’s head, the male lobster was around three feet long, he said.

The restaurant has seen lobsters that have weighed in at around 25 pounds but not for several years.

Customers who came into the restaurant Wednesday were wowed by the massive sea creature, which has been kept in a tank inside.

“People go in and go crazy,” Jordan told The Post.

Fortunately for this lobster, a pot of boiling water is not in its future. Jordan said the big guy will soon call the New York Aquarium home.
