The benthic invertebrate community—the population and species present—is strongly affected by its environment, including sediment composition and quality, water quality, and hydrological factors that influence the physical habitat. They range in size from microscopic mites and almost invisible flies to giant squid with soccer-ball-size eyes. Macro-invertebrates are very sensitive to environmental changes which is a good indicator to show the health of the pond. It occupies the strip of the Canadian mainland lying between Hudson and James bays to the north and the St. Lawrence River–Great Lakes chain to the south. As a group, invertebrates are extremely diverse, differing as much among themselves as they do from the vertebrates, which they greatly outnumber. While invertebrates are conspicuous on land, they are far more so in the sea. Aquatic invertebrates may live beneath the water, or they may live on the surface or on the plants surrounding it.

Benthic invertebrates were collected by divers along 25 transects (depths of2,5, 10, and 20 m) between the Niagara River and Kingston during July 1981. Grassland habitats provide a variety of ecosystem goods and services, and play an important role in supporting a healthy environment. Invertebrates are animals without a vertebral column (backbone). More than half of the samples had a more aggressive strain called Nosema ceranae. The most populous Canadian province, it is home to more than one-third of Canada’s population. Surprisingly advanced forms, including annelid worms and molluscs, have been found in rocks from the Canadian Arctic dating from the Precambrian period (more than 544 million years ago).

Some 95% of all animal species are invertebrates, 85% being arthropods. There are invertebrates that swim, float, fly, walk, crawl or burrow, and others that are fixed in one spot. Ontario’s Invading Species Awareness Program is a partnership between the Ontario Ministry of Natural Resources and Forestry (MNRF), and the Ontario Federation of Anglers and Hunters (OFAH). The Biological Survey of Canada (attached to the Canadian Museum of Nature) develops and co-ordinates work on invertebrates, and publishes a newsletter. Thus, the annelids and molluscs, though seemingly very different as adults, show remarkable similarities in their development.
