Crayfish excrete waste primarily through specialized organs called green glands, located near the base of their antennae. These glands filter waste products from the blood and help regulate water balance. The waste is excreted as a dilute urine-like solution, which is expelled through openings near the base of the antennae. This process is vital for maintaining the crayfish's internal environment and overall health.
Nephridiopores in crayfish are part of their excretory system (for removing nitrogenous waste); crayfish propel water from the rear to the front and out the nephridiopores. It is analogous to how humans have to expend their liquid waste.
The excretory system of crayfish, which involves specialized structures called green glands for waste removal, is unlike the human excretory system, which primarily relies on the kidneys. The respiratory system of crayfish, which involves gills for gas exchange, differs from the human respiratory system that uses lungs.
Crayfish
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 food that a crayfish consumes first goes through the gastric mill and into the stomach. Food then passes into the digestive system and digestive gland for further digestion and absorption. Undigested particles continue along the intestine and out the anus.
Crayfish are known as both crayfish and yabbies in Australia. "Yabbies" are freshwater crayfish, often found in rivers, creeks and dams in rural areas.
