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.
PREDATORS. Frogs have many predators. Animal predators include birds, fish and reptiles. Most rainforest frogs have pads of sticky hairs on their fingers and toes, as well as, loose sticky skin on their bellies, that make them great climbers to escape their predators. Many of these frogs live in high trees for safety. frog can change the colour of its skin depending on its surroundings. Humans have become a major danger for amphibians of all types. Water pollution is causing many deformities in frogs as well as poisoning them, and loss of habitat through the building of roads and houses.
