noun
craniate
Technical zoological term for animals with a skull; used in academic contexts.
有頭動物は脊椎動物の大部分を含む分類群である。
Craniates are a taxonomic group that includes most vertebrates.
脊椎動物 (vertebrate) is a broader, more common term; 有頭動物 is a stricter cladistic term focusing on the presence of a skull.
Compound of 有頭 (having a head/skull) and 動物 (animal). The exact historical derivation is uncertain; the term is a modern scientific coinage.
