Application of the neural markers, synaptotagmin and S1, reveals an extensive network of neurites and cell bodies in the ciliary band (CB) nerves, oral region, and digestive tract in the bipinnaria and in the attachment complex of the brachiolaria (Moss et al.
Brachiolaria larvae, which are characterized by a specialized attachment complex comprising three larval arms (brachia) and an adhesive disc, occur in the life cycle of many asteroids whatever their nutritional mode (planktotrophy versus lecithotrophy) or their developmental habitat (pelagic, benthic, or intragonadal) (McEdward and Janies, 1993, 1997; Byrne, 1999; McEdward and Miner, 2001; Byrne et al.
After 8 weeks, brachiolaria larvae with well-developed juvenile rudiments were induced to settle and metamorphose by addition of small cultured mussels (Mytilus edulis) and fresh pieces of macroalgae (Ulva spp.

But Bosch (1992) and Jaeckle (1994) showed that larval cloning is not taxonomically restricted when they reported larval cloning in brachiolaria larvae, which are common to all asteroid orders except the Paxillosida (to which Luidia belongs).
Bipinnaria and brachiolaria larvae of the asteroids Luidia foliolata and Pisaster ochraceus were surgically bisected into anterior and posterior portions, and the regeneration process was followed for 2 weeks (Vickery and McClintock, 1998).
Recently, brachiolaria larvae of the sea star Distolasterias brucei have been reported to undergo cloning in laboratory cultures (Kitazawa and Komatsu, 2000) in a manner identical to that described in previous reports (budding and autotomy).
