Description Longitudinal section of a female of an extant Antarctic brooder, Antrechinus mortenseni. This interior view of the test shows two brood pouches, each of which contains a juvenile at a different stage of development. Also shown are different internal organs (gonoducts, ovaries, water
vessels, etc.) and the birth canal through which the young move as they are released to the external environment through enlargement of the apical aperture.
