How long do quahogs live for?

Clams grow in seasons when the water is warm (April-October). You can count the growth rings like you would age a tree. Count the darkest rings, each ring represents 1 year. Now it's your turn!

Can clams live for 500 years?

The world's oldest animals, 500-year-old clams have given scientists an unprecedented look at the climate history of the oceans. By studying growth rings in the shells of quahog clams, scientists have pieced together the history of the North Atlantic Ocean over the past 1,000 years.

How old was the longest living clam?

At 507 years of age Ming the clam broke the Guinness World Record as the oldest animal in the world. Collected off the coast of Iceland in 2006, initial counts of the annual rings of the shell put the age at around 405 years old, which was still a record breaker.

How big can a quahog get?

Adult hard clams are just less than 3 inches, but can reach up to 5 inches. The shell is thick, grey to white in color, and has outer concentric growth rings.
