The octopus is an invertebrate animal (it has no backbone) and belong to the phylum (group) Mollusca. Its closest relatives are the various species of squid and cuttlefish.
There are none. The meaning of, or the reason for, vertebrate classification is that all the animals placed under this group have a backbone/spine. While it may not look similar to the human back, it is a back nonetheless. Animals with no backbone are invertebrates
reptiles because they have scaly dry skin and can live in water & on land surface areas
Arthropods are invertabrates (no backbone) which have segmented bodies and limbs. However, some arthropods, such as insects, have 3 body segments. Chelicerata - a group which includes spiders - have 2 segments, the cephalothorax and the abdomen.
