crabs have gills. They are tucked away in between their legs.
When lobsters are underwater they breath in oxygen, when they come above water they breath out carbon dioxide.
with gills like fishies
Lobsters have gills located under their carapace, which extract oxygen from water as it passes over them. The gills are essential for breathing and provide lobsters with the oxygen they need to survive. Lobsters also have a respiratory pigment called hemocyanin in their blood that helps transport oxygen throughout their bodies.
Our body obtain oxygen to our body by breathing.
Crustaceans obtain oxygen through gills.
Who is "they" ?
you obtain oxygen from your lungs you could breath through your nose and through your mouth
multicellular organisms obtain their oxygen through the respiratory system
Lobsters have gills located inside two branchial chambers. Water is pumped through these chambers by an apendage called the scaphognathite. Oxygen is extracted and the water expelled.
We obtain oxygen by breathing in fresh air. Carbon dioxide comes out of us.
No. The skeleton dose not get oxygen
Pterodactyls do not obtain oxygen at this time because they are extinct. While they existed, they probably obtained oxygen in the same way that birds today obtain it through the use of lungs.
