Abstract
Asexual reproduction by fission and regeneration
are two primitive characters exhibited by
echinoderms. Generally they reproduce asexually
fragmentation (fission), budding, parthenogenesis,
and polyembryony. Fission (autotomy) a common
method of reproduction usually involves the division
of the body into two or more parts and
regeneration of the missing body parts. This
phenomenon can occur in populations that are
reproducing sexually also.
