In shallow waters, sargassum can smother coral reefs and alter the water’s pH balance, killing off local seagrasses and mangroves. It can choke boat motors, constricting local fishing yields if not cutting off whole marinas. Sargassum once clogged a desalination plant so badly that residents of the U.S. Virgin Islands were told the drinking water may not be safe…

The reason patterns often appear in nature is simple: The same basic physical or chemical processes occur in many patterned substances and organisms as they form. Whether in plants and animals or rocks, foams and ice crystals, the intricate patterns that happen in nature come down to what’s happening at the level of atoms and molecules…
