Octopus and squids are mollusks.
All Squids are animals from the Class Cephalopoda of the Phylum Mollusca. Squids are not mammals, although bear in mind that all mammals are animals too, just from a different Phylum, Phylum Chordata.
No, squids do not have a placenta or an umbilical cord. In squids, fertilization of the eggs occurs externally, and the development of the embryos takes place outside the body of the female.
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.
