【海底忙什麼EP6】尼莫護卵 Amphiprion Ocellaris

【尼莫護卵 Amphiprion Ocellaris】

眼斑雙鋸魚受到肯氏綠海葵釋放出酪胺和色胺的吸引定棲共生。

牠們群體有清楚的社會位階，體型最大最富攻擊力之雌魚居上位，群中僅該尾雌魚和體型最大的雄魚有生殖能力。
眼斑雙鋸魚雌雄同體，先發育為雄性，一旦領袖雌魚死亡，群中最大的雄魚變性成雌魚遞補之成為領域主。眼斑雙鋸魚的卵黏在海葵旁邊或底下的礁石，卵緊密排列成近乎圓形的團塊，雌魚產卵之後雄魚排精成為受精卵。

橢圓形的受精卵數量依雌魚體型大小從 100 到 1500 顆 。眼斑雙鋸魚會育幼，雄魚負擔較多護卵工作，白天成魚搧動胸鰭讓水流通過卵以提供氧氣，吃掉被黴菌感染的卵或是沒有受精的卵，親魚持續護卵 7~8 天直到魚苗孵出。


Tyramine and tryptamine are secreted by the sea anemone, Stoichactis kenti, toelicit symbiotic behavior of the anemone fish, Amphiprion ocellaris.

In a group of A. ocellaris, a strict social dominance hierarchy exists within their societies. The largestand most aggressive female is found at the top. Only two anemonefish, a male and a female, in a group reproduce. A. ocellaris are sequential hermaphrodites, meaning they develop into males first. If the female anemonefish is removed from the group, such as by death, one of the largest and most dominant males becomes a female.
Eggs are laid in a roughly circular patch stuck to the reef next to or under the host sea anemone. The female lays the eggs and the male fertilizes them afterwards.

The number of oval-shaped fertilized eggs ranges from 100 to 1500 depending on female fish size. In terms of parental care, male fish are often the caretakers of eggs expending most of the time and effort. They parents continuously aerate the eggs by fanning to keep them oxygenated, and have responsibilities for eating fungi-infected or infertile eggs. Parents guard them for 7 to 8 days until they hatch.
