Question

Which canal system is the most efficient?

Answer 1

Canal system:

1. The canal system is an arrangement of intercommunicating cavities washed by the currents of water that help the sponges to carry out vital life processes like nutrition, respiration, excretion, reproduction, etc.
2. These canals are lined with cells that have long, whip-like tails called choanocytes.
3. There are three main types of canal systems: Asconoid, Syconoid, and Leuconoid.

Leuconoid system :

1. This type of canal system arises due to the additional folding of the body wall.
2. Leuconoid sponges are complex in that not all chambers are flagellated.
3. The flagellated chambers are small as compared to the asconoid and syconoid types. These chambers are lined by shape.
4. Water entering through the incurrent canals is pumped through those chambers and removed via one of a series of oscula.
5. Leuconoid sponges are the best modified to increase sponge size.
