Squid have gills along their sides... thus obtaining oxgen similar to a fish
Squid obtain oxygen from the water by passing it over their gills. As water flows through the gills, oxygen is absorbed into their bloodstream and carbon dioxide is released back into the water. This allows the squid to extract oxygen from their watery environment for respiration.
same way the 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.
They obtain oxygen form the water in the same way as fish do.
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.
for camoflauge so the squid can change color to better blend into its surroundings.
Squids obtain oxygen through their specialized gills. Water is taken in through the squid's siphon and pumped over the gills where oxygen is extracted and absorbed into their bloodstream. The gills work in a similar way to the lungs of mammals, allowing squids to extract oxygen from the surrounding water.
The skin is of a giant squid is covered in chromatophores, which enable the squid to change color to suit its surroundings. Like a chameleon
By actively hunting for it.
Oxygen - yes. Air - no. Not much of that around underwater.
Our body obtain oxygen to our body by breathing.
Like the octopus, the squid use ink and a camouflage to blind the enemy predator and blend into its surroundings. Some squids (like the Humboldt squid) use hook on their sucker cups to defend it's self.
