1995-2004 Southward et al. UK habitat and distribution of the warm-water barnacle Solidobalanus fallax (Crustacea: Cirripedia) records

New records are given of the occurrence of the warm-water barnacle Solidobalanus fallax in Britain and Europe. This barnacle is not found on rocks or stones, but settles on biological substrata, including algae, cnidarians, bivalves, gastropods and crustaceans. It also settles on plastic bags and nets, plastic-coated objects such as crab and lobster pots and octopus pots made of ceramic or plastic.With one exception the species was unrecorded in Europe before 1980; it may have increased in abundance during recent years as a result of rising temperatures.The cyprid larvae, which can metamorphose on plastic Petri dishes, appear to be adapted to seek out low energy surfaces. One of the habitats colonized by S. fallax is the sea-fan Eunicella verrucosa, where it seems to have increased in recent years, possibly to the detriment of the cnidarian host. Solidobalanus fallax has the potential to be a serious pest of fish-farming structures to the south of Britain.本文报道了暖水藤壶（Solidobalanus fallax）在英国及欧洲的新分布记录。该藤壶并不附着于岩石或石块表面，而是营固着生活于各类生物基底之上，涵盖藻类、刺胞动物、双壳类、腹足类及甲壳动物。此外，它还可附着于塑料袋、网具，以及蟹笼、龙虾笼、陶瓷或塑料材质章鱼笼等涂塑物体表面。除一例例外记录外，1980年以前欧洲尚未见该物种的分布记载；近年来其种群丰度或因气温上升而有所增加。其腺介幼虫（cyprid larvae）可在塑料培养皿上完成变态发育，似乎演化出了偏好搜寻低能表面的适应性特征。S. fallax的定殖生境之一为柳珊瑚（Eunicella verrucosa），近年来该宿主上的种群数量似有所上升，可能会对这一刺胞动物宿主产生不利影响。Solidobalanus fallax有可能成为英国南部水产养殖设施的重大有害生物。
