same way the fish do
They obtain oxygen form the water in the same way as fish do.
No. Marsupials are vertebrates, i.e. they have a backbone. Squid are invertebrates (no backbone). Marsupials have pouches. Squid do not. They release eggs into the water. Marsupials obtain oxygen by breathing, using lungs. Squid obtain oxygen through a pair of long 'gills' covered in leaflets called lamellae. Marsupials have fur, hair or skin. Squid do not. A kangaroo (for example) is a type of marsupial.
Squid have gills along their sides... thus obtaining oxgen similar to a fish
The vampire squid, generally found around the south carribean areas and along the coast of peru, obtain oxygen through the suction cups on their tenticles.
using their gills they obtain oxygen from the top of the water.
a siphon is an organ through which water is sucked in and out, either for filter-feeding or to produce oxygen. Also, it helps the squid move.
Every animal breathes oxygen, even fish (they obtain it by the oxygen in the water).
Cnidarians are able to absorb the oxygen they need from the surrounding water by diffusion.
ostichs is dont know
by drinking water
The two main sources for obtaining oxygen are the air - 23% of air is oxygen - and water by electrolysis.
We can obtain it by the Solubility method. These two gases has different volumes. Oxygen has 4 volumes which dissolves in 100 volumes of water and ammonia has 702 volumes which dissolves in 1 volume of water. They are insoluble and soluble in water respectively.
