Can crayfish breathe out of water?
Crayfish are crustaceans which resemble small lobsters. Crayfish, also known as crawfish or crawdads, live in fresh water and breathe with gills. Crayfish have gills for breathing underwater, but can also breathe air.
Respiratory System: Being aquatic organisms, crayfish have gills that aid in respiration . These featherlike structures are found underneath the carapace and are attached to the chelipeds and walking legs. Beside above, what is the function of the walking legs in a crayfish?
As a larger crustacean, the crayfish exclusively uses gills to breathe: These gills can be found on the sides of the crayfish and at the base of each leg, identified as a fuzzy grey or brown organ. Crustacean gills pull oxygen into the bloodstream as water passes through them, but these gills are sensitive – surprisingly so.
The Crayfish’s respiratory system uses gills. These Gills are connected to it’s legs. Whenever the Crayfish walks, it uses it’s legs to filter the water for respiration. The Crayfish has a water “pocket” allowing it to walk on land as well.
Crayfish need a lot of oxygen, so it definitely good to have an air pump to add oxygen to the water. With this they can remain submerged 24/7.

Crayfish have gills for breathing underwater, but can also breathe air. The crayfish will molt, shed its exoskeleton.
The circulatory system of the crayfish is an open system where the blood is contained in vessels for only part of the system. The heart is located in a pericardial sinus located in the upper part of the thorax (a sinus is a sac or cavity). The heart pumps the blood into the arteries.
In the parastacid crayfish, the typical gill comple- ment consists of 12 developed and 5 rudi- mentary gills, whereas the genus Cherax has 21 plus a rudimentary epipod (Hobbs, 1974), which is the same as for the redclaw cray- fish.
Respiration Most crustacenas use gills to breathe. For example, a crayfish has a gill at the base of each leg. These gills are very delicate and are covered by the crayfish’s carapace, or shield.
Explanation: A crawfish, due to its specialized gills which enable it to breathe normal air, can survive for several days outside water as long as their gills are moist. If they live in humid conditions, they can survive for months.
