What is grill attach to on crayfish?
The grill, or gills, of a crayfish are attached to the base of the walking legs, specifically at the thorax. These gills are responsible for respiration, allowing the crayfish to extract oxygen from the water. They are feathery structures that increase surface area for gas exchange, enabling the crayfish to breathe while submerged.
Where is the sperm duct located in crayfish?
In crayfish, the sperm duct, also known as the vas deferens, is located within the male reproductive system. It runs from the testes, which are situated in the abdominal segment, to the base of the fifth pair of walking legs. This duct serves to transport sperm from the testes to the outside during mating.

How do crayfish excretory?
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.
Which lymphatic structures are located at the base of the tongue?

Where is the basal body located?

What structures form a protective ring of lymphatic tissue surrounding the internal openings of the nose and mouth?
The structures that form a protective ring of lymphatic tissue surrounding the internal openings of the nose and mouth include the tonsils, specifically the palatine tonsils located at the back of the throat, and the lingual tonsils located at the base of the tongue. These structures help filter out and trap pathogens from entering the respiratory and digestive systems.
