Invertebrates

From bees to worms, spiders to snails, invertebrates make up 98% of animal life. In Scotland they are present from the top of Ben Nevis to the bottom of the North Sea, although nobody knows quite how many species there are. Between terrestrial and freshwater environments alone, Scotland may be home to some 50,000 species.
