Long Island Sound Fun Fact

Long Island Sound is 113 miles long, 21 miles wide (at its widest) and holds about 18 trillion gallons of water. Its average depth is 63 feet – which is just a little deeper than the height of our IMAX screen! Can you fathom that?!

Aquar.lobster copy

Common Name: American or Northern lobster

Latin Name: Homarus americanus

Size/weight: Extreme cases: up to 40 pounds and 3 feet long

Range: Labrador to Cape Hatteras; most common from Nova Scotia to New York

Habitat:  Crevices or burrows in rocky reefs and muddy bottom habitats

Diet:  Fish, mollusks and other crustaceans scavenged on or near the bottom.

Predators: Sharks, cod, wolfish, goosefish, striped bass, and people with bowls of melted butter.

Description: Most common coloration is greenish brown, but genetic and other factors can produce lobsters of a wide variety of colors.  Two large front claws, one for grabbing and crushing, the other for ripping and tearing.  Eight legs extend from the carapace, segmented abdomen and wide tail.

Conservation Note: Lobster populations have not rebounded since a devastating die-off in Long Island Sound in 1999.  Warming waters due to climate change threaten the lobster's long-term prospects in the Sound.
