Cement glands
Small organs in thorny-headed worms / From Wikipedia, the free encyclopedia
Cement glands are small organs found in Acanthocephala that are used to temporarily close the posterior end of the female after copulation.[1]

Cement glands are also mucus-secreting organs that can attach embryos or larvae to a solid substrate. These can be found in frogs such as those in the genus Xenopus,[2] fish such as the Mexican tetra,[3] and crustaceans.
