From Pakistan total 11 genera and 14 species of sea cucumbers have been recorded belonging to the orders Aspidochirotida and Dendrochirotida to which most of the commercial species belong.
All currently known fissiparous species of holothurians belong to two orders: Aspidochirotida and Dendrochirotida. Asexual reproduction was first described in dendrochirotids.
There is a huge diversity of species of sea cucumbers (66 species) that are harvested commercially and traded around the world, with the majority of these species belonging to the order Aspidochirotida, and only a few to the order Dendrochirotida (Purcell et al.

Apodida can discard the posterior region of the body (Pearse, 1909; Domantay, 1931; Baugh, 1991), whereas autotomy in the Aspido-chirotida and Dendrochirotida takes the form of auto-evisceration, which is characterized by the extrusion of internal organs through a rupture in the body wall (Emson and Wilkie, 1980; Byrne, 1985, 1986; Dolmatov, 1996, 2009).
After the first cleavage, the fixing processes near the cleavage furrow can be as long as 60 [micro]m This rivals the length of the acrosomes of the sea cucumber Dendrochirotida thyone (Tilney and Inoue, 1982)--a well-known example of the long actin fibers in gametes.
Evidence for the tubule recruitment model was limited to holothurians of the orders Aspidochirotida and Dendrochirotida. Comparative information on oogenesis in other holothurian orders was considered too limited to assess the model's general applicability (Smiley, 1988).
