Presentation transcript:

Spend entire lives at sea Stream-lined bodies

Breathe air through blowhole

Front flippers; tail = “fluke”

Blubber for insulation Slow reproductive rate; 1 calf / 2-3 years Beluga & Calf

“Moustached” – baleen plates hang from upper lip Flexible, fibrous plates of keratin to strain water

Baleen

Eat krill, small fish, crustaceans Krill

2 Blowhole openings

Rorquals – grooves along throat/chest to expand Ex: humpback, finback

Humpbacks Feeding

Humpbacks Size: ft

Body black, often w/barnacles (gooseneck barnacles) Flippers to 15 ft; white underneath; used to ID

Behaviors: Breaching

Feeding with Bubble Net Whales swim in circle blowing bubbles trapping fish inside “net”, then swim up center

Lunge Feeding Swim through school & engulf food & water

“Greyhounds of the Sea” – to 20mph Lifespan yrs 2 nd Largest animal on Earth – to 85 ft

Known for elaborate songs

Blue Whale Largest animal; 100 ft

Person standing between blue whale jaw bones

Blue Whale

Right Whale Carcasses float; slow “Upside-down smile” Most endangered Size: to ft

Teeth to catch & hold prey; swallowed whole Eat fish, squid, seals

Single blowhole opening

Often travel in pods

Ex: SPERM WHALE Largest toothed whale (40-60ft); feed on Giant Squid; dive deep

Orca or Killer Whale Spyhopping

Dolphins: beak & conical teeth Porpoises: blunt head & flat teeth

Echolocation Sounds sent from sacs in head (melon) Received through jaw to inner ear (like SONAR) Used for navigation, socialization, predation
