摘      要：Cirripede-like organisms have their origins in the Palaeozoic,but until the Cainozoic,were represented primar­ily by pedunculated forms,such as the *** barnacles(Balanomorpha)are first recorded af­ter the Cretaceous-Tertiary extinction *** the late Palaeogene,rapid radiation of cirripedes resulted in sufficient diversification for them to occupy most marine *** they survived both the Palaeo­cene-Eocene Thermal Maximum and the Pleistocene glaciation is testament to their ability to rapidly adapt to *** wide habitat distribution of balanomorphs in particular is unparalleled;they are known from the upper littoral(Chthamalus)to depths of 3600 m(Tetrachaelasma)and within this attached to rock,wood and miscellaneous flotsam,plus in symbiosis or commensalism with larger marine ***’s(1854)view of the Tertiary as the age of barnacles is reflected in this diversity,distribution and *** cirripedes are,nonetheless,at risk,from rapid habitat change,competition,pollution and,especially in light of their sessile habit,from *** paper assesses the viability of a number of cirripedes and concludes that the Lepad­iformes,Scalpelliformes and Balanomorpha are the most resilient,and will most quickly adapt to occupy new niches when opportunities arise.
