Dunaliella

Dunaliella thrives in salt concentrations that would kill almost anything else - up to 35% salt (ten times seawater). At these extreme concentrations, it turns bright pink-red from beta-carotene accumulation, coloring salt lakes worldwide. This extremophile is commercially cultivated for natural beta-carotene production.

Dunaliella demonstrates extremophile market positioning - thriving where competitors can't survive. By tolerating conditions lethal to others, it faces no competition. The business parallel is extreme niche positioning: serving markets so demanding or unusual that mainstream competitors won't or can't enter, creating natural barriers to competition.
