  • The Life Cycle of a Worm features the four stages of a surprisingly complex creature. Their lemon-shaped eggs give birth to hatchlings, which slowly grow to juveniles. Months later, they become adult worms, capable of beginning the cycle anew.
  • Scientific Name: Lumbricus terrestris
  • Characteristics: Worms may look simple, just a slender tube slithering through the dirt, but they are complex creatures that work hard to improve soil tilth and quality.
  • Size and Color: Matching the pinkish-brown color of earthworms, the figures come in a 7 ¾ wide by 9 inches tall blister pack, about the size of a tablet. The adult worm featured in the set measures 3 ½ inches long.
  • The Life Cycle of a Worm is part of the Safariology® collection.
  • All of our products are Non-toxic and BPA free.


Here’s a little-known fact: those ubiquitous earthworms beloved by gardeners are not native to northern North America! That’s right, most native earthworms were wiped out by glaciers thousands of years ago, and today’s species hitched rides on the ships carrying settlers to the continent. The worms themselves don’t mind; they simply go about the long process of turning leaf litter and decaying material into useful soil. Slow is the word, though, as it can take many months for worm eggs to hatch and grow into adult worms. That smooth band on earthworms? That’s the sign a worm is an adult, and it’s also a clue about the worm’s anatomy, as the smooth band is always closer to the worm’s head.
