Many animals found in Canada have become part of the country’s iconography. The beaver, the caribou, the loon and the polar bear, for example, all grace our currency, while moose, narwhals and others are pictured in regional emblems. If asked to name the creatures that roamed Canada long before these familiar ones, many might cite Tyrannosaurus rex or Triceratops, two of the 88 species of dinosaur found here (see Dinosaurs Found in Canada). But between dinosaurs and today’s beavers — a period of about 225 million years — whole ecosystems flourished and disappeared in Canada, and networks of animals with them. Below are five prehistoric Canadian animals. Two of them, Albertonectes and Cryodrakon, were contemporaries of the dinosaurs. Three others, the giant beaver, mammoth, and American mastodon, existed millennia later.

Flatfish is the common name for fish belonging to the order Pleuronectiformes. There are 14 families of flatfish and over 800 species worldwide. In Canadian waters there are approximately 39 species of flatfish, from five families. These families are Pleuronectidae, Bothidae, Paralichthyidae, Scophthalmidae and Cynoglossidae. Familiar flatfishes found in Canada include halibut, plaice, flounder and turbot. Among their distinguishing features, flatfish have both eyes on one side of their body.

Fleas are very small, wingless, laterally flattened insects of the order Siphonaptera. They’re best known for being external parasites on mammals and occasionally birds. Adult fleas live in the fur or feathers of their hosts, feeding on their blood to survive and reproduce. While fleas do feed off humans, more common host animals include rodents, dogs and cats. The “human” flea, Pulex irritans, actually attacks a broad range of mammal species, and the same is true of most flea species that bite humans. About 2,000 species and subspecies are known worldwide, with at least 127 found in Canada, most of them in British Columbia and Alberta.

Floods are primarily caused by naturally occurring changes in the height of rivers, lakes and oceans. According to Public Safety Canada, floods are the most common natural hazard in the country and among the costliest. Historic floods have occurred across Canada, with many of the worst happening on major river systems that pass through populated areas. Scientists predict that flooding linked to the impacts of climate change will increase as the 21st century progresses, particularly in coastal areas of the country.

Adult flies have sucking or piercing mouth parts and lack the mandibles with which other insects bite food. Many so called "biting flies" (eg, horseflies, mosquitoes, no-see-ums, black flies, stable flies, tse-tse flies) feed on VERTEBRATE blood.
