Like this, A diver first had to hand harvest it from the sea floor, extracting the sponges isn't a quick or simple task.

像這樣，一個潛水員首先要從海底手工採摘，提取海綿並不是一個快速或簡單的任務。

At times, divers must grab hold of a sponge with both hands using their force and a bit of wiggling side to side to extract one.

有時，潛水員必須用雙手抓住海綿，利用他們的力量，左右扭動一下，才能取出一塊海綿。

It's important that they leave enough sponge substrate attached to the seabed.

重要的是，他們要在海床上留下足夠的海綿基質附著。

That way the sponge has the potential to regrow and the population can be sustained at a separate processing facility, producers clean batches of the extracted sponges to remove any remaining black residue from the sea, although bigger sponges are worth more.

這樣一來，海綿就有可能重新生長，並且可以在一個單獨的加工設施中維持種群，生產者將提取的海綿分批清洗乾淨，以去除海中任何剩餘的黑色殘留物，儘管更大的海綿價值更高。

Workers often cut them down.

工人們經常把它們砍下來。

This makes a sponge easier to clean and bathe with and naturally more marketable.

這使得海綿更容易清潔和洗澡，自然也更有市場。
