Description: | This species lives in fast flowing rivers and streams throughout Europe and North America. It has a strange life cycle. When the larvae hatch they can swim, and attach themselves to the gills of fish. After a year they drop off and settle onto the river bed where they grow into adults. They can live for over 100 years and don't start to reproduce until they are 12 years old. Unfortunately they are threatened with extinction, mainly due to pollution. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | animals North East natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
