Fresh Water Invertebrates in the Aquarium & Natural Waters

Invertebrates are all around us. They make up approximately 95% of all animals on the earth. Some of the more well known invertebrates are insects, crustaceans and marine inverts like starfish and sea urchins.

There are also many different types of freshwater invertebrates. Some are permanently aquatic and some only live in the water for a part of their lives.

My intent in these pages is to provide useful and easily understandable information on the most commonly seen fresh water invertebrates. The General Information page is a good place to start if you aren't familiar with the animals or are interested in learning a little more. In that page I've also included brief taxonomical information and how I have organized the Fresh Water Invertebrate Pages.

For specific information about different animals you can go right to the animals page, listed below. For more information about fresh water invertebrates check out the books listed in the Bibliography and other web pages in the Links page.
