The Grantia Canal System is called the "Sycon (syconoid) Canal System." This means that the canals from the sponges inside (excurrent canals) and those from the outside (incurrent canals) of its body wall end blindly, but are connected at right angles by openings called prosopyles. This type of canal system is intermediate in canal complexity. The canals are the pathways the water takes through the sponge.

Alimentary Canal
Good answer, but this is somewhat incorrect. The optic nerve is the continuation of the retina exiting out of the posterior part of the eye. The retina is the inner most layer of the eye covering the interior surface. The Canal inside of the eye is called the Hyaloid Canal, which contained the Hyaloid Artery during fetal development. In the later stages of fetal development, the Hyaloid Artery, which exists to provide nutrients to the lens during development, regresses and therefore leaves behind the Hyaloid Canal. Its main purpose is serving as a fluid passageway. Hope that wasn't too much detail. Good original answer though. You were close. The Hyaloid Canal extends from the lens to the optic disc (head of the optic nerve).
