2. BluntnoseSixgill Shark Phylum: Chordata Scientific name: Hexanchusgriseus Location: Widely distributed over temperate and tropical seas. Also found in Canada’s Pacific waters Population: Est. 8000 in the N.E Pacific but this number is rapidly decreasing

3. BluntnoseSixgill Shark Habitat: Found in waters below 91 m over the waters of outer continental and insular shelves Diet: Pacific Salmon, mollusks, crustaceans and other species depending on the water they dwell in Mating behaviour: The male will nip at the female’s gills to initiate mating

4. Phylum: Chordata • Other species: • The Spotted Wolffish • Fin Whale • Steller Sea Lion • Sei Whale • Sea Otter • Blue Whale (Atlantic) • Green Sturgeon • The Pugnose Minnow • Atlantic Whitefish • American Eel • The Spotted Sucker • Leatherback Turtle • Humpback Whale (N.

7. The Spotted Wolffish Scientific Name: Anarhichas minor Location: Arctic Ocean, both sides of the N. Atlantic Ocean Habitat: Cold, deep waters Diet: Crustaceans, mollusks (bottom-dwelling invertebrates) Mating Behaviour: little is known Population: Rapidly declining (at risk of extinction)

8. Steller Sea Lion Scientific Name: Eumetopiasjubatus Location: Along the coasts of California to the Bering Strait, and along the coasts of Asia and Japan Habitat: Beaches (gravel, rocky, sand), ledges, reefs

9. Steller Sea Lion Continued Diet: Schooling fish (i.e. herring, salmon), squid Mating Behaviour: Between May and July, the adults gather in a designated area for mating and birthing Population: 19,000 in Canada

10. Sea Otter Scientific Name: Enhydralutris Location: North Pacific Ocean Habitat: shallow, coastal waters (close to shore), areas with kelp canopies Diet: shellfish & sea urchins Mating Behaviour: violent, male chases female around Population: 150,000 worldwide

11. Green Sturgeon Scientific Name: Acipensermedirostris Location: Pacific Ocean (from Mexico to Alaska) Habitat: bottom-dwelling, salt water Diet: shrimp, crabs, shellfish, & other bottom-dwellers Mating Behaviour: males reach maturity at 15, females at 17, use freshwater as spawning sites Population: est. in the tens of thousands

12. Atlantic Whitefish Scientific Name: Coregonushuntsmani Location: Unique to Canada, found in Nova Scotia Habitat: believed to have inhabited coastal waters Diet: amphipods, small periwinkles & marine worms Mating Behaviour: spawn in fresh water Population: almost extinct, exact numbers unknown

13. The Spotted Sucker Scientific Name: Minytremamelanops Location: eastern and central North America Habitat: clear lakes, creeks Diet: molluscs, aquatic insects Mating Behaviour: takes place from May – April over gravel in shallow waters Population: endangered Spotted Sucker Distribution in Ontario

14. Leatherback Turtle Scientific Name: Dermochelyscoriacea Location: Atlantic, Pacific, Indian Oceans, and the Mediterranean Sea Habitat: nest on warm tropical beaches Diet: jellyfish, squid Mating Behaviour: occurs in waters beside nesting areas Population: 2,300 in the Pacific

15. Humpback Whale (N. Pacific) Scientific name: Megapteranovaeangliae Population: Est. 20,000 worldwide (20% their original pop.) Location: north Pacific, Rigid waters of Hawaii, Alaska and Canada Habitat: favour areas that offer protection against prevailing winds Deit: krill, small shrimp-like crustaceans, other small fish Mating Behaviour: Males go around impregnating the females. A mother whale can have calf's from more than one male

16. Harbour Porpoise (Pacific) Scientific name: Phocoenaphocoena Population: Est. low thousands Location: The Pacific and the Northwest Atlantic waters Habitat:  bays and harbours (mainly during the summer), stay within reach of food Diet: small fishes (i.ecod, herring, hake, capelin and sandlance). Mating Behaviour: Males mate with females (females are usually 3 when they are mated)

17. Fin Whale (Pacific) Scientific name: Balaenopteraphysalus Population: Est. 10,000 Location: Canadian Pacific waters and around northern European countries Habitat: Cold water (Polar Latitude Temperature) Diet: Plankton and Trill Mating Behaviour: Males select their mates

18. SeiWhale Scientific name: Balaenoptera borealis Population: Est. 14,000 (20% more than the original population Location: Pacific oceans (many in the coast of British Columbia) Habitat: found in deep offshore habitats, do not usually enter icy waters Diet: primarly plankton Mating Behaviour: Males swim and challenge each other, while the female chooses her mate

19. The Pugnose Minnow Scientific name: Opsopoeodusemiliae Population: endangered Location: Lakes and rivers of Central America (i.eWisconsin, Ontario) Habitat: Warm, vegetated rivers with little currents Diet: Zooplankton and larvae of aquatic insects such as midges Mating Behaviour: Males select their mates (who are under flat rocks)

20. Blue Whale (Atlantic) Scientific name: Balaenopteramusculus Population: Est. 12,000 Location: Atlantic Oceans Habitat: Cold, deep ocean waters. Diet: Krill and Plankton Mating Behaviour: Whales sing to one another to attract each other

21. American Eel Scientific name: Anguilla rostrata Population: endangered Location: eastern coast of N. America Habitat: Salt ponds, muddy bottoms of freshwater rivers Diet: Aquatic insects, worms, small fish Mating Behaviour: spawns in oceanic waters
