fissiparity การใช้

• Active fissiparity seems to be correlated with 6 arms and 4 madreporites.
• In " Sclerasterias ", fissiparity seems to be confined to very young individuals.
• "Coscinasterias calamaria " mainly reproduces by fissiparity ( self division ) by tearing itself in two pieces across the disc.
• Fissiparity in the starfish family Asteriidae is confined to the genera " Coscinasterias ", " Stephanasterias " and " Sclerasterias ".
• In echinoderms, this method of reproduction is usually known as "'fissiparity "'. Researchers claim today that due to many environmental and epigenetic differences, that clones originated in the same ancestor might actually be genetically and epigenetically different.
• A sample of 36 young " Sclerasterias euplecta " of this size was examined . 9 had only 5 arms and did not show evidence of fissiparity while the remainder had 6 arms, usually 3 longer than the other 3, following prior fission.
