Q:

How long do giant squids live?

A:

While not conclusive, evidence suggests the lifespan of the giant squid is no longer than five years. The speculation is derived from mineralized masses called statoliths in the deep-sea creature that produce growth rings used to measure age.

Adult giant squid grow to an average of 33 feet, with the largest recorded specimen measuring 59 feet long. The largest invertebrate in the world also possesses eyes 10 inches or more in diameter, the largest of the animal kingdom.

At 1,650 to 3,300 feet below the water surface, the giant squid is nearly impossible to observe in its natural habitat. Much of what scientists know as of 2014 is from observing dead species that washed ashore.
