PhylumRank below Kingdom. Groups organisms sharing a fundamental body plan (e.g., Chordata = vertebrates and some invertebrates).Chordata
ClassRank below Phylum. Subdivides by structural traits (e.g., Mammalia, Aves, Reptilia, Insecta).Reptilia
OrderRank below Class. Groups related families sharing common ancestry (e.g., Carnivora, Primates).Squamata
FamilyRank below Order. Groups closely related genera (e.g., Felidae = cats, Canidae = dogs).Dipsadidae
GenusRank just above Species. The first word in the two-part binomial scientific name.Leptodeira
Taxonomic AuthorityThe scientist who first formally described and published this species, followed by the year of publication.Günther, 1868
