Observers have reported siphonophores and salps in Hong Kong waters. 香港水域最近發現了管水母及海樽的行蹤。
Both siphonophores and salps can be considered “gelatinous plankton” and are often lumped in with jellyfish in this broad category. Although these two can look similar, salps are actually tunicates, which have a primitive structure similar to a human backbone. Salps are individuals that can take advantage of environmental conditions to reproduce both sexually and asexually to create long chains spreading across large areas of the ocean. They filter particles from the water to eat and do not sting like jellyfish.
管水母及海樽都屬於gelatinous plankton，通常也被歸入水母這一大類當中。雖然外形類似，海樽其實是海鞘的一種，擁有與人類脊椎相似的主要結構。海樽可以利用環境因素，進行有性及無性繁殖，在廣大海域中散佈。牠們可以過濾水中物質以作進食，不會像水母一樣蟄人。
Siphonophores are a collection of individuals that work together to create a mutually beneficial larger organism. Some parts are responsible for catching prey, some reproduce and some are responsible for movement. These creatures do have stinging ability and are able to catch crustaceans and small fish to consume.
管水母由多個個體組成，整體緊密連結、互相依存成為一大形生物。有些部份負責捕食獵物、有些部份負責繁衍、也有些部份負責移動。這些生物會蟄人，也會捕捉甲殼類動物及小型魚類作食用。
These two animals can have significant impacts on marine ecosystems if they achieve high enough population density, eating their way through marine resources. Keep an eye out for these fascinating creatures!
如果這兩種生物的密度持續增加，可能會侵食海洋資源，將會對海洋生態有重大影響。請記得留意這些有趣的生物！
