【璀璨新生】海洋大明星 - 小丑魚
小丑魚 Amphiprioninae
小丑魚是對海葵魚亞科（Amphiprioninae）魚類的俗稱，目前已知約30種；又因小丑魚與海葵密不可分的共生關係，又稱海葵魚（Anemonefish）。小丑魚最大的特色便是性轉變，在一群小丑魚當中，往往體型最大者為雌性，次者為雄性，其餘則性徵未顯；當母魚(體型最大)死去，則原本的公魚(體型第二大)將轉變成母魚，而性別原本未分化的小魚中，體型最大者將變成公魚，然而最終成為母魚後就無法變為公魚。這種情況被稱作「順序性雌雄同體」。
The 30 or so known species of clownfish belong to the subfamily Amphiprioninae. They all form inseparable symbiotic relationships with sea anemones. Because of this, they are also called ‘anemonefish’. One of the most notable features of clownfish is their ability to change sex. Usually, the largest and second-largest individuals in a population of clownfish are a mature female and a breeding male, respectively, while the rest of the population consists of sexually immature fish. If the female dies, the breeding male will replace it by changing into a female, and the largest of the immature fish will mature into a new breeding male. Female clownfish cannot become males again. This irreversible phenomenon is called ‘sequential hermaphroditism’.
【璀璨新生】珊瑚礁中的湛藍波紋 - 疊波蓋刺魚
疊波蓋刺魚 Pomacanthus semicirculatus
多見於珊瑚礁的疊波蓋刺魚，幼魚和成魚外表差異極大。幼魚體色為深藍色，並帶有許多白色弓狀紋路，而成魚卻是偏黃黑色的。一般潛水時會看到的是幼魚，因幼魚比較喜歡在較淺水的地方生活，成魚會到較深的地方。
Semicircle angelfish are usually found on coral reefs. The adults and juveniles differ greatly in appearance. Juveniles have a deep dark-blue body that is marked from top to bottom with a series of narrow white arcs. Adult fish, in contrast, are yellow and black with no such arcs. Divers generally encounter juveniles, which tend to live at shallower depths than the adults.
