Definition of hemichordate in English:

hemichordate

noun hɛmɪˈkɔːdeɪtˌhemiˈkôrdāt

Zoology

A marine invertebrate of the phylum Hemichordata; an acorn worm.
Example sentencesExamples
- Molecular phylogenies have suggested that hemichordates are in fact a sister lineage to the echinoderms.
- Unfortunately, a change in the genetic code of the mitochondrial genome in both enteropneusts and echinoderms strongly rejects chordate affinities of the hemichordates.
- Size comparisons between living and extinct hemichordate zooids are not conclusive evidence, however, as it is easy to imagine a small, hypothetical, zooid that possessed multiple tentaculated arms.
- The molecular phylogeny does agree in one respect with the morphological one in that there are close similarities between the larvae of hemichordates (acorn worms and pterobranchs) and some echinoderms.
- We chordates are deuterostomes, as are echinoderms, some marine worms called hemichordates, and the urochordates, or sea squirts.

adjective hɛmɪˈkɔːdeɪtˌhemiˈkôrdāt

Zoology

Relating to or denoting hemichordates.
Example sentencesExamples
- Evidence for the hemichordate affinity of the extinct graptolites has been steadily amassing.
- They lack two others, the notochord and post-anal tail, hence the name hemichordate.
- The hemichordate sequences always contained considerable support for both hypotheses.
- Unfortunately there are no living fenestrate hemichordate species.
- There are two classes of hemichordate, the pterobranchs and the enteropneusts, which differ greatly in appearance and lifestyle.
