Crayfish come in different colours. They can come in blue, white and red. Red is the more common type and white is the least.
They are often given a number of different names including crawdads, crawfish, river crab, and mudbugs.
The Swedish consume approximately 2,000 tonnes of Crayfish every year
A single serving of boiled crayfish is 3 ounces, approximately 85 grams. Three ounces of crayfish meat contains 70 calories, with only 9 calories of this coming from fat.
