what happens when you cut a worm in half

When you cut a worm in half, the outcome depends on the species of the worm. For some worms, such as earthworms, cutting them in half will not result in two separate worms. The head of the worm may survive and regenerate its tail if the animal is cut behind the clitellum, but the original tail will not be able to grow a new head and will instead die. However, earthworms can survive if their tail end is cut off, and can regrow their segments to some extent. Some species of worms can regenerate and grow a new tail if their tail is cut off, but they may have difficulty growing a new tail if cut too closely to their head. In some cases, the tail end of a worm will regenerate new tail segments rather than a head, which can prolong the worms life temporarily, but it cannot eat. Its important to note that not all worms will regenerate into two separate worms when cut in half, and the outcome varies depending on the species of the worm.
