We have thus a total of 453 species recorded for Loch Ness, excluding 
all Vertebrata, blue-green Algae, and some other groups on which no 
work has been done. The Hydrachnida, Insecta, Worms, Infusoria, 
Chlorophyceae, and Diatoms have all been insufficiently studied, and 
the lists could be easily increased.
