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) One of Bergey's Manual of Systematic Bacteriology. Being a deep branching phylum (cf. Bacterial phyla) its classification was analysed in Volume One of Bergey's Manual of Systematic Bacteriology and included a single class with the same name, the class "Chloroflexi". Since 2001 however, new classes have been created thanks to newly discovered species, therefore currently the phylum "Chloroflexi" is divided into: Regarding the class "Dehalococcoidetes", the placeholder name was given by Hugenholtz & Stackebrandt, 2004, after "Dehalococcoides ethenogenes" a partially described species in 1997,<ref name="doi10.1126/science.276.5318.1568"></ref> whereas the first species fully described was "Dehalogenimonas lykanthroporepellens" by Moe et al. 2009, but
