The primary excretory product of crayfish is that of a small amount of ink. Due to evolution present day crayfish no longer possess a large ink bladder. This is due to the shallow water they reside in and the extra weight the bladder would have put on the animal.
The crayfish can excrete wastes through blood. Blood is forced through the arteries that empty into spaces within the body cavity. Once the blood has drained through these spaces and bathed the organs, it collectst in the large ventral sternal sinus. As the blood circulates, the green gland filters out waste materials. The fluid waste is then excreted through a pore just anterior to the mouth.
Waste is eliminated by excretory organs called "green glands."
The antennal gland. (or "green gland", common to crabs and other Malacostraca )

Many people confuse the process of excretion with the removal of waste products of digestion. Excretion, however, is actually the removal of all the waste products produced by the cells of the body.
Excretion!:)
I think for me the process of excretion with the process of defecation is by the process of excretion with the process of defecation. Therefore the defecation is the process of excretion by the process of defecation. Some says excretion is the process with the defecation process. That's why the organ contrast the process of excretion with the process of defecation.
Crayfish are known as both crayfish and yabbies in Australia. "Yabbies" are freshwater crayfish, often found in rivers, creeks and dams in rural areas.
