Most invertebrates probably don't have hair due to their environment
most invertebrates are arthropods, and 70% of animals in the world are arthropods (insects), so I'm guessing there are more invertebrates than vertebrates.
squid
yes
yes most ..invertebrate are edible...
I do not know if there is an exact percentage, but I do know that the of the known species, the most are invertebrates. This is because bugs are invertebrates. There are so many different species of bigs, just the insects alone, that we cannot find and name them all. Also you have many other groups of invertebrates.

Most likely they are living things.
they dont have a backbone
