The Land Planarian (Bipalium kewense) a most unusual and most intriguing creature. It is also known as the Arrowhead Flatworm. Originally thought to be from Indo-China, the Land Panarian was discovered living in the United States over 100 years ago.

Depending on environmental conditions, some asexual worms also develop complex hermaphroditic reproductive organs from planarian pluripotent stem cells, or neoblasts. Acquired sexual worms then mate, and eventually lay a cocoon filled with several fertilized eggs and a large number of yolk gland cells.

Land planarians are rare in rural sites. Movement and feeding occur at night. High humidity is essential to survival. Leeches, Tubifex, & Planaria Worms Worms are actually many different animals from several major unrelated invertebrates that share a similar body shape. Leeches, tubifex and earth worms are all in the same phylum, Annelida, meaning segmented worm. Annelids have bodies made of a series of segments. Planaria are small flatworms from the phylum Platyhelminth.
