A salp is a semi-transparent, gelatinous zooplankton that is part of a group of animals known as sea squirts. It glides through the ocean by pumping water through its body, utilizing one of the most efficient examples of jet propulsion in the animal kingdom. The salp swims alone for a part of its life, but spends the rest with other fellow salps, linking together in chains or colonies that are arranged into beautiful spirals and shapes. Every salp starts its life as a female, then becomes a male but never switches back, and no one knows why. Scientists believe that salps may play a vital role in limiting the effects of climate change, because they produce large, fast-sinking pellets of carbon-rich poop, carrying carbon to the depths of the ocean with them. Their carcasses also act the same way and provide a food source at the sea floor.

 

果凍魚是一種半透明凝膠狀的浮游生物,屬於被稱為海鞘的動物群的一部分。他利用動物王國裡最有效的噴射推進例子之一:通過身體抽水在海洋裡滑行。果凍魚一生中有時會獨自游,但其餘的時間會與其他果凍魚群一起度過,連結彼此成一鏈或一群,排列成美麗的螺旋形狀。果凍魚會以雌性開始生命,然後轉變成雄性,並且不再變回雌性,沒有人知道原因。科學家們認為,果凍魚也許在降低氣候變遷影響方面扮演著重要角色,因為他們會產生大量、快速下沉且富含碳的糞便顆粒,將碳帶到海洋深處。他們的屍體也以同樣的方式發揮作用,並在海底提供食物來源。
