A syconoid is pertaining to or resembling a sycon.
sponges
asconoid sponges, and syconoid
The three types of sponge canal systems are asconoid (simplest and least common), syconoid (intermediate complexity), and leuconoid (most complex and found in the majority of sponge species). These systems differ in the degree of complexity of their canal structures and their efficiency in water filtration.
there are really many types of sponges. One is the octopus sponge people love this kind because it contians a lot of fluid inside it. Another type is the seahorse sponge with is huge and it can bite through a shark. it is the size of two elephants! one more sponge is the lily pad sponge it is a light green with the smell of frog on it, it doesnt smell nice and it eats dolphins which IS MEAN!
Choanocytes (also known as "collar cells"). Choanocytes are found dotting the surface of the spongocoel in asconoid sponges and the radial canals in syconoid sponges, but they comprise entirely the chambers in leuconoid sponges.
Unique stuctures of Phylum Porifera include 1 : Spicules which may be calcarious or silicious . 2 : Canl system , which may be asconoid , syconoid or leucon type . 3 Spongin fibers in some fresh water sponges .
Sponges with a leuconoid body type are the most efficient in terms of maximizing the surface area for nutrient exchange and can grow to larger sizes compared to other body types like asconoid or syconoid. These sponges have complex canal systems that increase the efficiency of nutrient uptake and waste removal.
The most efficient sponge body type that allows for the largest body size is the leuconoid type. This structure features a complex arrangement of canals and chambers that maximizes surface area for filter feeding while minimizing the resistance to water flow. The increased surface area enables larger sponges to effectively filter more water and nutrients, accommodating their greater size. As a result, leuconoid sponges can reach significantly larger dimensions compared to asconoid or syconoid types.
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.
It has no symmetry, and they have jelly like cells that transport food throughout the body. Collar Cells: fires spines that traps food. Spiky things: Protects the Sponges's body.
