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) root is "Chlorobi", whereas "Cyanobacteria" has the root "cyanos (κύανος)" meaning "blue-green". Unlike some other phyla, there is no theme root in the name of genera of "Chloroflexi" and in fact many genera beginning with ""Chloro-"" or ending in ""-chloris"" are either cyanobacteria or chlorobi. Chloroflexi (phylum) The Chloroflexi or Chlorobacteria are a phylum of bacteria containing isolates with a diversity of phenotypes including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures, anoxygenic phototrophs, which use light for photosynthesis (green non-sulfur bacteria), and anaerobic halorespirers, which uses halogenated organics (such as the toxic chlorinated
