Fossil range Hemichordates were present throughout the mid-Cambrian, but recently a large and well-preserved pterobranch discovery places them in the early Cambrian.  [details]

Etymology The name hemichordate is derived from the Greek prefix hemi ("half") and the Latin chorda ("cord"). As the name implies, hemichordates share some characteristics with chordates. [details]

Fossil range Hemichordates were present throughout the mid-Cambrian, but recently a large and well-preserved pterobranch discovery places them in the early Cambrian.  [details]

Habitat Hemichordates have been found living in a wide variety of depths and habitats. [details]

IUCN Red List Category Not Evaluated [details]

Importance Hemichordates are of much research interest because they can help elucidate chordate and deuterostome origins. Also, some hemichordates have the ability to regenerate, and thus studying their development and regeneration may benefit human health.  [details]

Original description The first hemichordate described was Ptychodera flava, by Eschscholtz in 1825. [details]
