What's the difference between peduncle and polyp?

Peduncle


Definition:

  • (n.) A sort of stem by which certain shells and barnacles are attached to other objects. See Illust. of Barnacle.
  • (n.) A band of nervous or fibrous matter connecting different parts of the brain; as, the peduncles of the cerebellum; the peduncles of the pineal gland.

Polyp


Definition:

  • (n.) One of the feeding or nutritive zooids of a hydroid or coral.
  • (n.) One of the Anthozoa.
