Molecular phylogeny of hemichordata, with updated status of deep-sea
enteropneusts. Mol.
Notably, support for
enteropneust monophyly is moderate (65/0.99), and SH testing did not reject the alternative hypothesis (
enteropneust paraphyly).

A comparative molecular approach to mesodermal patterning in basal deuterostomes: the expression pattern of Brachyury in the
enteropneust Ptychodera flava.
It is robust and can be collected intact, unlike many other species of
enteropneust, which are fragile and easily broken.
Given the unquestionable shared form of the hemichordate pharynx with that of fossil echinoderms and protochordates, I decided to investigate the potential for filter feeding in the
enteropneust worm Harrimania planktophilus.
How is the pterobranch feeding apparatus and ciliation similar to an
enteropneust's proboscis and collar?
Brachiopods, sipunculans,
enteropneusts and metals from two estuarine tidal flats, Pacific, Costa Rica.
"Our description of Spartobranchus tenuis, a creature previously unknown to science, pushes the fossil record of the
enteropneusts back 200 million years to the Cambrian period, fundamentally changing our understanding of biodiversity from this period," he added.
The discovery of a 500-million-year-old penis-shaped fossil has provided a missing link that pushes back evolution of
enteropneusts by 200 million years.
Yoda purpurata -- to be exact -- is the name now given by a University of Aberdeen-led team of scientists to one of three new species of deep sea acorn worms or
Enteropneusts discovered 2,500m or around 1.5 miles below the surface of the Atlantic Ocean.
La Paz, Baja California Sur; commensal of
enteropneusts. *Lepidasthenia ornata Treadwell, 1937: 145-147, pl.
