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
Starfish site and Sheffield. The new "Special Fire" decoys were set up to simulate the bomb drops of German pathfinder squadrons. By 23 January 1941 the programme had been increased to 43 sites protecting 13 town and cities and by March operational sites numbered over 100. By the end of the war there were 237 Starfish sites protecting 81 locations. One of the first decoy sites was constructed on Black Down on the Mendip Hills; it was code-named "Starfish", derived from Turner's original SF code, and built to protect the nearby city of Bristol. The Starfish name was eventually adopted to describe
