2 SUH-TAY-SHUNS !!

3 CETACEAN From the Latin cetus, meaning a large sea animal From the Greek ketos, meaning a sea monster Taxonomic Order of marine mammals including whales, dolphins and porpoises

4 Taxonomic Comparison HUMANBLUE WHALE KINGDOM:AnimaliaAnimalia PHYLUM: ChordataChordata CLASS: MammaliaMammalia ORDER: PrimatesCetacea FAMILY: Hominidae Balaenopteridae GENUS: HomoBalaenoptera SPECIES: sapiensmusculus

5 Mysticeti vs. Odontoceti * ~10 recognized species* ~70 recognized species * 2 blowholes * females larger than males * 1 blowhole * males larger than females * teeth are used to catch prey, but not for chewing * age determined by counting growth layers in waxy ear plug * age determined by counting growth layers in teeth the baleen whales the toothed whales * baleen plates act as a sieve to strain organisms from the water * undertake lengthy migrations between distinct breeding and feeding grounds * make smaller seasonal movements (inshore-offshore)

6 Basic Anatomy Rostrum 2 blowholes Caudal fin or fluke Pectoral fin Baleen plates Throat pleats of a mysticete Dorsal fin

7 MYSTICETES Baleen plates hang from upper jaw only and vary in size, color and shape. Gray whales have creamy-colored baleen.

8 Right whales have black baleen plates.

9 Baleen is made of keratin – same protein as human hair and fingernails! This is a humpbacks open mouth.

10 Crustaceans called KRILL are a major food source for many of the worlds mysticetes.

11 Heres a look at open blowholes…

12 …and heres what they look like closed.

13 Migaloo: the worlds only known albino humpback whale

14 Migaloo breaches and offers a rare look at his all-white body.

15 Basic Anatomy of an odontocete Dorsal fin 1 blowhole Rostrum Pectoral fins Caudal fin or fluke Teeth

16 ODONTOCETES Teeth come in all shapes and sizes, too. These are the conical shaped teeth of a killer whale.

17 Here is the single open blowhole of a bottlenose dolphin.

18 And lets not forget the Unicorn of the Sea the arctic Narwhal

19 Dolphins vs. Porpoises Prominent beak and melon Longer, more sleek bodies More tapered pectoral fins Cone-shaped teeth No true beak and melon is streamlined Short, stocky bodies Blunt pectoral fins Spade-shaped teeth …so what IS the difference, anyway?!

20 Sperm Whale Bottlenose Dolphin Harbor Porpoise Stejnegers Beaked Whale Bairds Beaked Whale Teeth are uniform throughout a cetaceans mouth because they are not specialized for purposes of chewing. They are strictly for catching prey or tearing flesh. Food is swallowed whole.

21 Whale Camp, Grand Manan Island

23 Highest & Lowest Tidal Range

24 Investigating local ecosytems The carnivorous Pitcher Plant in the bog

25 One of the Bay of Fundys impressive inverts!

26 Visiting a Puffin nesting colony

27

28 Razorbills nest there, too.

29 So do the Common Murres…

30 …and Terns also.

31 Watching a Harbor Porpoise dissection

32 And lets not forget the WHALES!

33 Distinctive V-shaped blow of a Right Whale

34 Flukes are entirely cartilagenous.

35 North Atlantic Right Whales are critically endangered

36 Mottled belly of a female suggests male suitors are courting beneath the surface.

37 They are positively buoyant so they need to thrust their flukes out of the water in order to make a dive.

38 San Ignacio Lagoon, Baja Mexico Winter breeding and calving grounds for the Gray Whale

39 Mother and calf

40 An encounter with the Friendly Whale Syndrome thats me!

41 Valentina was a favorite.
