What's the difference between earthworm and silkworm?

Earthworm


Definition:

  • (n.) Any worm of the genus Lumbricus and allied genera, found in damp soil. One of the largest and most abundant species in Europe and America is L. terrestris; many others are known; -- called also angleworm and dewworm.

  • (20) Conjugation with glutathione catalysed by glutathione S-transferases may consequently be an important detoxification mechanism in earthworms.

Silkworm


Definition:

  • (n.) The larva of any one of numerous species of bombycid moths, which spins a large amount of strong silk in constructing its cocoon before changing to a pupa.

Example Sentences:
