Mandapam
The Indo-Pacific shallow water species
of Sea star Linckia multifora collected
from Mandapam coast reared in research
aquarium, has shown fissiparous
reproduction. This method of asexual
reproduction is called autotomy and this
is restricted to a very few species of sea
stars. It is achieved by shedding an arm
which result in comet, and this will further
develop into a separate sea star with
central disc.
