Portuguese man o' war
The Atlantic Portuguese man o' war lives at the surface of the ocean. The gas-filled bladder, or pneumatophore, remains at the surface, while the remainder is submerged. As the Portuguese man o' war has no means of propulsion, they move according to the winds, currents, and tides. Although they are most commonly found in the open ocean in tropical and subtropical regions, they have been found as far north as the Bay of Fundy, Cape Breton and the Hebrides.
Cantonese opera
There are two types of Cantonese opera plays: "Mou" (武, "martial arts") and "Man" (文, "highly educated", esp. in poetry and culture). "Mou" plays emphasize war, the characters usually being generals or warriors. These works contain action scenes and involve a lot of weaponry and armour. "Man" plays tend to be gentler and more elegant. Scholars are the main characters in these plays. Water sleeves are used extensively in "man" plays to produce movements reflecting the elegance and tenderness of the characters; all female characters wear them. In "man" plays, characters put a lot of effort into creating distinctive facial expressions and gestures to express their underlying emotions.
