Mystery microbes of the sea
Biologists find archaea a true curiosity. They make up one of life’s three main branches. The two better known branches are bacteria and eukaryotes (u KARE ee oatz). That last branch includes animals, plants and fungi. But archaea have remained mysterious. Very little is known about them. In fact, their unique status wasn’t even recognized until relatively recently, in 1977.
