Earthworm Facts

The earthworm, originally from Europe, can be found all over the world, notably in North America and western Asia. Earthworms are some of the least complex invertebrates and are herbivores.

  1. Body Composition

    • The bodies of earthworms are divided into annuli, ring-like sections easily visible to the naked eye. Tiny bristles called setae are found on each annulus, and it is with these that an earthworm moves.

    Importance

    • Earthworms are important to farmers and gardeners because the nutrients they remove from deep in the ground are re-deposited near the surface through their waste, improving soil health.

    Uses

    • Because of their fertilizing capabilities, many people add earthworms to their compost piles and gardens. Earthworms are also useful as bait for fishing.

    Myth Vs. Fact

    • A lot of strange information about earthworms is floating around, and some of it is true. For example, all earthworms are hermaphrodites and reproduce by exchanging sperm. Each worm forms an egg as well. However, the myth that worms that are cut in two can form two new worms is false.

    Fun Fact

    • The world's longest earthworm, discovered in South Africa, measured 22 feet in length.
