More than 35 years later, Bdellovibrio biology is undergoing a revival owing to the original, pioneering genetics work of Thomashow and colleagues (13), which has been followed up by genome sequencing and the development of new gene inactivation methods to study the function of these bacteria (32, 42, 60).
They also have five pairs of eyes. The Freshwater Leech is a parasite that feeds on the blood of fish, frogs, turtles, and mammals. It should not be confused with other leeches, most of which prey only on insects, snails, and small creatures.
