Do worms feel pain when cut in half?

What is the lifespan of worms?
At birth, earthworms emerge small but fully formed, lacking only their sex structures which develop in about 60 to 90 days. They attain full size in about one year. Scientists predict that the average lifespan under field conditions is four to eight years, while most garden varieties live only one to two years.
Can a worm live if cut in half?
If an earthworm is split in two, it will not become two new worms. The head of the worm may survive and regenerate its tail if the animal is cut behind the clitellum. But the original tail of the worm will not be able to grow a new head (or the rest of its vital organs), and will instead die.

How deep can worms go underground?
They burrow during the day—typically keeping close to the surface—capable of digging down as deep as 6.5 feet. The worm’s first segment contains its mouth. As they burrow, they consume soil, extracting nutrients from decomposing organic matter like leaves and roots.

What is the smallest worm?
Nematodes are small worms that measure around 1 millimetre long and live freely in soil or water. They feed on bacteria, single-cell algae, fungi or other nematodes; they can also parasitise other animals or plants. But the most striking fact about them is their ability to adapt.
Do worms have brains?
Do worms have brains? Yes, although they are not particularly complex. Each worm’s brain sits next to its other organs, and connects the nerves from the worm’s skin and muscles, controlling how it feels and moves.
