How do crabs obtain oxygen?
Breathing free and easy. Crabs, like many sea-dwelling creatures, have gills that they use to extract oxygen from the water in order to breathe.
How are crabs able to find their prey?
Like many other marine animals, crabs rely on their sense of smell to find prey. Crabs have chemoreceptors that allow them to detect chemicals in the water that are released by their prey.
Why is cellular respiration important to the blue crab?
Cellular respiration is the process in which glucose is broken down to produce ATP in the mitochondria. In order to breathe cellular respiration must occur ( C6H12O6+O2→H2O+CO2+ ATP). ATP is especially important because it stores energy. Energy is also required to survive.
Where does the oxygen in a blue crab come from?
This is where oxygen travels in the cells. Because blue crabs are small they are able to let out carbon dioxide across the exterior of their body. Carbon dioxide is produced when the oxygen has finished circulating the body. Oxygen is dissolved in water when blue crabs breathe it in.

How are blue crabs able to breathe in water?
Diffusion occurs in their gill membranes. On each side of a blue crab there are eight gills. Along with blue crabs being able to breathe in water with their gills, they can breathe out of the water with their gills. The only way they can do so is by keeping their gills wet.
