2 how big |
To start off, can anyone guess how big a humpback whale can get? |
|
|
3 45 rope |
(Guessing) An adult female can get as big as 45 ft. The males are a little smaller at about 42 ft. To give you an idea of how long 45 ft is, we have a very sophisticated piece of equipment here, we have our rope. Can I please have my volunteers come up and help hold the rope? |
|
|
4 45, 42, 15, 1, ton |
This rope is 45 ft long, so this is how big a female humpback whale can get, the second tag from the end is 42 ft which is how long a male can get, so a little smaller. The third tag is 15 feet which is about how big a calf is, and this last tag is a one foot, and for every foot of an adult whale's length it will weigh 1 ton or 2000 lbs. So a 45 ft whale can weigh 45 tons or 90,000 lbs. That's pretty big right? ! |

7 help blow |
When we are out on the ocean looking for whales, we are going to need everybody's help today, so if you see something let one of our crew know so we can investigate. When we spot whales, usually the first thing we are going to see is the blow. This is a picture of a blow and what this is, is the whale breathing. |

|
8 300 mist 20ft, visible |
When the whale comes to the surface to breathe, the air in its lungs is expelled at 300 mph, which sprays the water that collects on the flap covering the whale's blowholes into a mist. The blow can reach as high as 20 ft but will only be visible for a few seconds depending on weather conditions, so we will have to keep a good lookout for a blow. |
