Goniopora-eating Phestilla
Phestilla goniophaga
背上刻意長出一顆白色小圓點,假扮成角孔珊瑚的水螅體,混進餐桌大啖「主人」。
It grows a white dot on its back to pose as a coral polyp, then eats its way through its own host: the ultimate dinner guest.
體長最大約 3 公分,背上突起多達 16 列、每列最多 23 根,在同屬裡特別多。專吃角孔珊瑚,卵塊是少見的鮮橙色絲帶。2020 年才在香港橋咀洲和赤洲命名,種名就是「吃角孔珊瑚的」。
Up to 3 cm, with up to 16 rows of cerata and up to 23 per row, unusually many for Phestilla. It eats only Goniopora coral and lays bright orange egg ribbons. Named in 2020 from Hong Kong waters; the name means "Goniopora-eater".
