GENERAL CHARACTERSTICS OF BIPALIUM
- It is one of the largest land planarians measuring 20 to 50 cm in length. It was discovered in the green houses of the knew gardens in U.K. by Moseley (1878).
- Animal consists of an expanded lunate head and cylindrical long body.

- Reproduction generally asexual. It never becomes sexual in temperate climate and it propagates by fragmentation.
- Bipalium adventium breeds sexually.
- If subjected to desiccation, it recovers water loss, provided the loss does not exceed, 45% of its weight.
The specimen contains a semi-circular head and all above features, hence it is Bipalium.
