Starfish by the starfish in an escape response. The loss of parts of the body is achieved by the rapid softening of a special type of connective tissue in response to nervous signals. This type of tissue is called catch connective tissue and is found in most echinoderms. An autotomy-promoting factor has been identified which, when injected into another starfish, causes rapid shedding of arms. The lifespan of a starfish varies considerably between species, generally being longer in larger forms and in those with planktonic larvae. For example, "Leptasterias hexactis" broods a small number of large-yolked eggs. It has an adult
Chloroflexi (phylum) the members of the phylum Chloroflexi are monoderms, but stain mostly Gram negative. The taxon name was created in the 2001 edition of Volume 1 of Bergey's Manual of Systematic Bacteriology and is the Latin plural of the name "Chloroflexus", the name of the type genus of the phylum, a common practice. In 1987, Carl Woese, regarded as the forerunner of the molecular phylogeny revolution, divided Eubacteria into 11 divisions based on 16S ribosomal RNA (SSU) sequences and grouped the genera "Chloroflexus", "Herpetosiphon" and "Thermomicrobium" into the "Green non-sulfur bacteria and relatives", which was temporarily renamed as "Chloroflexi" in Volume
