倒立水母

Upside-down Jellyfish

Cassiopea andromeda

簡介

水母界的躺平族。比起四處漂泊，牠們更喜歡倒立在溫暖的淺灘沙地上。

The couch potatoes of the jellyfish world. Rather than drifting, they prefer to rest completely upside-down on warm, shallow sandy bottoms.

牠們之所以要倒立，是因為觸手組織內共生著蟲黃藻。牠們必須像植物一樣把「葉片」朝上曬太陽來進行光合作用。

They rest upside-down to expose the symbiotic zooxanthellae (algae) in their tentacles to the sun, allowing them to photosynthesize for energy.

尚無潛點紀錄。
