POBBLEBONK - PANEL 3

MICROSCOPIC WORLD

THE RIVER

The smallest animals and plants in the river are too small to be seen with the naked eye. There is a microscopic world teeming with thousands of species of viruses, bacteria, micro algae and protozoa. There can be hundreds of thousands of these creatures in a litre of river water and more in a litre of the sediment or mud. All of these are eaten by a swarm of small animals known collectively as microinvertebrates (animals less than 2 mm), which include crustaceans, worms, molluscs, fish hatchlings and others that can only be recognised under a microscope. The animals shown here are just a very small selection of these microinvertebrates.

 

THE WETLAND

The microinvertebrate world of freshwater pools in the floodplain has a similar make-up of crustaceans, molluscs, worms and fish hatchlings but also includes insect larvae and small multi-celled animals called rotifers. Insects become an important part of the community in the freshwater part of the river and wetlands.
