Abstract:
This Environment Agency booklet presents invertebrate fauna of the tidal Thames. Tidal Thames is divided in this document in upper estuary, the freshwater zone; mid estuary, the brackish zone; and outer estuary, the marine zone. The once grossly polluted Thames has been cleaned up to such a degree that it now supports a significant fish population The return of over I 10 species offish to the river, where in the 1950 s only eels
could survive at certain times of year, is explained in another Agency leaflet entitled Fish Found in the Tidal Thames. Less well known is the return of numerous small animals known as invertebrates (animals without backbones). These usually go unnoticed, living in the depths of the river, hiding under rocks, in the mud or drifting in the surface layers as plankton. Without these animals the fish would be without food and could not survive.
