Bipalium kewense

Here is the most interesting thing about Land Planarians, also known as a Hammerhead Worms, from UF’s Entomology & Nematology Dept:

Reproduction is principally by fragmentation at the posterior end. Lateral margins pinch in about 1 cm from the tail tip. Severance occurs when the posterior fragment adheres to the substrate and the parent worm pulls away. The posterior fragment is motile immediately, and within seven to 10 days a lightly pigmented head begins to form. One to two fragments are released each month.
