DNA study reveals hidden biodiversity off Brazil—and raises alarm over oil exploration SOFIA MOUTINHO S trewn across seabeds worldwide are hard, pinkish nodules, some as large as a soccer ball, built over centuries by tiny calcareous algae. Known as rhodoliths or “rolling stone reefs,” these stony expanses don’t look as luxuriant as other marine habitats such as coral reefs.
