Corpuscles of Herbst

They differ from Pacinian corpuscles in being smaller and more elongated, in having thinner and more closely placed capsules, and in that the axis-cylinder in the central clear space is encircled by a continuous row of nuclei.

Kiwis, sandpipers, and ibises have Herbst corpuscles on their bill tips allowing them to sense vibrations.

[1] They are named after the German embryologist Curt Alfred Herbst.

In many wading birds, a large number of Herbst corpuscles are found embedded in pits on the mandible that are believed to enable birds to sense prey under wet sand or soil.
