Not exactly. Humans, birds, and reptiles are all within the phylum chordata, while arachnids and insects are both within the phylum arthropoda.
But all fish, no matter which classification you use, are also part of the phylum chordata, just like reptiles, birds and mammals. @mech@feddit.orgs statement still holds true.
