In nasogastric (NG) intubation, a tube is placed through your nose into your stomach. Your healthcare provider can use an NG tube to feed you and give you medicine. They can also apply suction to an NG tube to remove stomach contents.
Crayfish, also called crawfish or crawdad, any of numerous crustaceans (order Decapoda, phylum Arthropoda) constituting the families Astacidae (Northern Hemisphere), Parastacidae, and Austroastracidae (Southern Hemisphere). They are closely related to the lobster.
Crayfish are oviparous animals. After mating, the female keeps the eggs in the swimmerets near her tail, located under the abdomen. When the eggs hatch, the tiny baby crayfish stay on the mother's tail until they are big enough to swim independently. They eat tiny bits of food that are floating in the water.
