Craniata is a Phylum, (scientific classifacation), It means that an organism has a skull, or cranium that contains the brain.
I believe that Craniata more accuratelydescribes the group

Snails like other invertebrates do not have spinal cord nor one single brain. Instead they have a set of ganglia (groupings of neurons) that distribute the control of the organism to different areas. For example a snail like other mollusk (phylum Mollusca) have a buccal ganglia to control the mouth.

Craniata
I believe that Craniata more accuratelydescribes the group
Urochordata, represented by tunicates; Cephalochordata, represented by lancelets; and Craniata, which includes Vertebrata.
Homo sapiens (humans), Gallus gallus (chickens), and Mus musculus (mice) are all examples of organisms in the chordate phyla.
Freshwater and saltwater fish are in the same phylum that we are, and reptiles and amphibians and birds are in; phylum chordata, subphylum craniata, subphylum vertebrata.
Keeping aside reference of other craniata, the anterior bone of the human skull is called "os frontale" or the frontal bone of the skull.
Fish have backbones and like all animals with backbones the phylum is chordata. There are further subclassifications in chordata; those with complete skulls are in the craniata subgroup.
The phylum Chordata is organized into three subphyla: Urochordata (tunicates), Cephalochordata (amphioxus), and Vertebrata (vertebrates). These subphyla are distinguished by specific characteristics, such as the presence or absence of a backbone, which differentiate them within the larger phylum Chordata.

Lampreys belong to the group of jawless fish known as Petromyzontida. They are known for their unique disc-shaped mouth with rows of teeth that they use to attach to other fish and feed on their blood and body fluids. Lampreys have a cartilaginous skeleton and a simple, tube-like body form.
