Crayfish
Crayfish (also called crawfish or crawdads) are freshwater crustaceans that look like a small lobster. Crayfish feed on plants, frog eggs, insects, and small fish. Crawfish boils and dishes with crayfish in them are very common in Louisiana. Louisiana supplies about 95% of the crayfish harvested in the US.

Which directions do the mandibles move on crayfish?
Yes, they have three sets of maxillipeds, which tear the the food apart. The maxilla also rips the food side to side. The mandible does the final grinding and it also help pass the food into the deepest part of the mouth which contain the lateral/median teeth.
How many ears do crayfish have on their body?
A crayfish can have as many eggs as it wants it just has to be healthy but I think it can lay 50-200.
Can cray fish breathe air and water?
That depends largely on the species of crayfish, but as a general rule, yes, crayfish can breath air as long as their gills are wet. Most cannot be out of the water for more than about 20 minutes.
hi, yea they are right they do breathe with gills. but its a little more complicated than than lol
Class Malacostraca Order Decopoda
Being largely aquatic, most larger crustaceans breathe via gills. Their gas exchange system is closed (cf. the open system of insects), and the oxygen that diffuses through the gills is either transported in simple solution in the haemolymph, or bound to blood pigments such as haemoglobin or haemocyanin.
Crayfish gills are located between the carapace (the exoskeleton of the cephalothorax) and the lateral body wall, in the branchial chamber.
Oxygen and carbon dioxide are exchanged between the blood and water across the gill surface as water is circulated through the branchial chamber by the beating of the gill bailer on the second maxilla.
An astacid is a member of the Astacidae, a group of animals comprising freshwater crayfish.
Crayfish are omnivores, meaning they are both an herbivore and a carnivore.
What are the uses of the cray c90?
The Cray C90 is what is termed as a "supercomputer". This means that it has a particularly high capacity and processing speed, allowing it to be used in situations where a lot of data needs to be processed at top speed.
What is the function of the ostia in a crayfish?
It pumps newly oxygenated blood that's come from the gills into the heart, to circulate again.
What is the difference between washed and unwashed crawfish?
In my opinion when we wash the craw fish it does not become dry and when we do not wash it it is dry from the first this is my answer of this question
