Reproducing females bear a prominent brood pouch ( marsupium ) between their thoracal legs.
2.
It is normally found living in the host's marsupium and devouring its eggs.
3.
The marsupium must also be kept filled with water until the young hatch and crawl away.
4.
Scavenging and cannibalism are also common, with the adults sometimes preying on their young once they emerge from the marsupium.
5.
Several hundred eggs are brooded at a time in the marsupium, a pocket on the ventral side of the female pill bug.
6.
Marsupials are named after the pouch, or " marsupium ", in which their young spend most of their foetal development.
7.
The huge entrance doors, made of vengai ( pterocarpus marsupium ) wood, are studded with unrusting iron knobs each of a different pattern.
8.
The carapace often extends beyond their heads to form an elongated brood pouch, or " marsupium ", and thus lack a separate planktonic larval stage.
9.
Larvae of the nominate subspecies have been recorded on " Pongamia pinnata ", " Millettia atropurpurea " and " Pterocarpus marsupium " in India.
10.
The eggs, which may number up to several hundred, are brooded by the female in the marsupium, a chamber formed by flat plates known as oostegites under the thorax.
