The great potential of regeneration in sea cucumbers
is demonstrated through the phenomena of
evisceration and asexual reproduction by fission.
In evisceration, the sea cucumbers expulse most of
their internal organs due to physiological change
or in response to varied external factors. Within a
certain period of time the eviscerated sea cucumbers
regrow new internal organs and live normally.
The process of regrowing internal organs occurs in
asexual reproduction as well.
