10 Hard Facts About Lobsters

Lobsters are weird, wonderful, and most importantly, essential predators of their ecosystem. They play an important role keeping sea urchins and other animals in check, which protects the kelp forests in which many species flourish. Learn more about these fascinating crustacean heroes.

Lobsters Are Cannabalistic


So it turns out that lobsters like a nice lobster dinner. They are opportunistic feeders, and if lobster’s on the menu, they don’t mind a bit. This tends to hamper the development of lobster farming, as one might imagine.

They Have Poor Eyesight


As bottom dwellers, lobsters don’t have much use for sharp vision. Their eyestalks are sensitive to light and dark, but lobsters do most of their sensing through taste and smell, at which they are experts.

Lobsters Are Almost as Long-lived as Humans


Lobsters can live up to 50 years in the wild.

Like a Tree, a Lobster Just Keeps Growing


As a lobster ages, it just keeps getting bigger and bigger, molting and shedding its shell over and over. In fact, scientists can tell a lobster’s age by counting the rings in its eyestalk, just like you would count rings in a tree trunk.

The Longest Lobsters Are More Than 3 Feet Long


As far as we know, there’s no upper limit to a lobster’s size, although it’s hard to tell since the largest ones don’t fit into lobster traps and are rarely caught.

A 44-Pound Monster Lobster Was Caught off the Coast of Nova Scotia in Canada


Scientists think this “Old Man of the Ocean” was at least 100 years old.
