Can Planaria regenerate if cut vertically?
Answer: Planaria possesses great power of regeneration. Thus if the body is cut into two vertical halves, each piece of the body of Planaria grows into a complete individual.
Why do worms have 5 hearts?
The aortic arches function like a human heart. There are five pairs of aortic arches, which have the responsibility of pumping blood into the dorsal and ventral blood vessels. The dorsal blood vessels are responsible for carrying blood to the front of the earthworm’s body.
How do you kill worms?
Kill the earthworms in alcohol Put the earthworms in the alcohol one at a time (rather than a whole handful all at once) so they don’t get tangled up into a big mess of earthworms. After a few seconds, the earthworm will become anesthetized and relax into a mostly extended position.

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.

What causes planaria to regenerate?
Regeneration in planarians depends on the presence of stem cells called neoblasts. These cells are distributed throughout the body and, when part of the worm has been amputated, they are activated to reform the tissues that have been removed (Wagner et al., 2011).
Do worms have 5 hearts?
Heartbeats: Worms don’t have just one heart. They have FIVE! But their hearts and circulatory system aren’t as complicated as ours — maybe because their blood doesn’t have to go to so many body parts. Moving around: Worms have two kinds of muscles beneath their skin.
Do worms have a face?
Taken altogether, some have eyespots, some have structures called probosci and others have mouths. I don’t know of any species that have all three but there may well be some. If a face is made up of eyes, noses and mouths – then some might have what could be called a face. In terms of recognition – only in fantasies.
