Planarian Regeneration Part 1.mov

Planaria are non-parasitic flatworms of the biological family Planariidae, belonging to the order Seriata. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas. These animals move by beating cilia on the ventral dermis, allowing them to glide along on a film of mucus. Some move by undulations of the whole body by the contractions of muscles built into the body membrane. They exhibit an extraordinary ability to regenerate lost body parts.

never put it on a blender!!!!!

A very good detailed video of regeneration. A quality supposedly present only in lower invertebrates and limited in vertebrates with exceptions. In the mythological stories of India, characters (human) had ability to regenerate lost or cut parts of the body - Like Ravana (the ten headed demon king), Mahishaasura from blood got new total body regenerated . However your video satisfies the biologic mind about the process of asexual reproduction in emergency- the regeneration

Wew it's a good thing these Planarians aren't parasitic or else we're doomed DX

[xXDarylTanXx]

If human were to regenerate like this particular flatworm, there is no end to human population. Just cut yourself into half and generate a new you! How cool is that? Uncool......

@blabla1233890 your just so stupid it's unbelievable.

[septicmonk]

@blabla1233890 Oh god buddy you are ignorant.  These Planarians naturally reproduce this way, via asexual fission. A Planarian anchors its posterior end and pulls forward and literally tears itself in two. Cutting it up does nothing but accelerate this process. Besides, biologists aren't randomly cutting up animals like a dumbass elementary school student just cause they can. Research such as this improves our understanding of not only these wonderful creatures but ourselves as well.

What would happen if the head and tail were cut, but there was a small fragment in the middle holding the halves?

[magicmike1122]

So you dont actually have to reproduce them. Instead, you just cut them in half and they keep multiplying
