SUMMARY OF **EARTHWORM REGENERATION STUDIES**  
**HOMELAB PUNE -**  
 → On oct 6 I got 1 earthworm and kept it in tissue paper cup culture  
 → On oct 22 I amputated the earthworm  
I cut more than 20 segments from its tail end.  
After amputation I got 2 pieces  
Long head piece  
And short tail piece

**TAIL PIECE WITH REGENERATED HEAD**  
Tail piece of Earthworm amputated on 22 Oct  
The tail piece regenerated a new head  
But the tail piece disappeared 81 days after amputation

* * *

→ On 21 December I amputated 3 earthworms to see whether tail pieces will regenerate or not-

_Earthworm-1_: ~20 segments from tail end  
_Earthworm-2_: ~ 20 segments from tail end  
_Earthworm-3_: ~30 segments from tail end cut

I was expecting all the 3 head pieces and all 3 tail pieces to regenerate..

I’ve been culturing earthworms at my HOMELAB since October 2021 but i still don’t know their species  
please give some suggestions on how to identify earthworms

What makes earthworm regenerate? Do humans also regenerate? how can we connect earthworm regeneration with humans?
