There’s a new attraction at Jordan Lobster Farms on Long Island.

A 20-pound lobster currently resides in his own private tank at the Island Park fish market and restaurant, enjoying plenty of scallops, clams and attention from customers.

The extra-large crustacean, christened “The Donald” because of his size and strength, was caught by commercial fishermen in the Bay of Fundy in Nova Scotia.

Lobsters reach about 1 pound at seven years of age, and put on 1⁄4 pound every year thereafter, bringing The Donald’s age to about 84, guesses owner Steve Jordan.

Lobsters this big are extremely rare, “one in a million,” Jordan says, “or at least one in 100,000.”

How does a 20-pound lobster taste? Jordan’s customers will never know. The Donald is headed not to the kitchen but to a permanent home at the New York Aquarium in Coney Island.
