PowerPoint Presentation 8 - Salish Sea...For gray whales, the size and placement of white markings...

Today, we’re going to teach you how to draw an orca. What better way to get acquainted with their shape, contours, and body parts than to sketch one yourself?! *You will be using this sketch for our Wednesday’s Whale Wit, so once you’re done (and have given your orca a name!), hang on to him/her for more information! *If drawing a “him”, make sure to give your orca a much TALLER dorsal fin!

Draw a “sideways egg”

Add an oval, soft triangle, and cone

Add some wavy linesfor a tail

Add detail for the orca’sface and include shapes in

the white areas

Curve an “open” mouth in; clean up some lines

(erase).

Add cone-shaped teeth, tongue and side of mouth;

draw an eye.

Clean up (erase) and connect the fin to the back,

and the back to the tail

Create curve for bottom of mouth, add baleen and eye;

clean up lines (erase) and add “divot” on top of head

Clean up (erase) tail, connecting belly and back with clean lines

Create pattern along the back that looks like your knuckles

when you make a fist

Add unique markings to the tail and along the back (each

gray whale is different!)

TUESDAY SALISH SEA WHALES: LEARN BY DOING EDITION

Today, we’re going to have you use your orca from Monday and your gray whale from Tuesday to label their body parts! You can also use the illustrations below to play along!

Whales are especially adapted to live in their water environments. “Adapted” means that they have specific body shapes and body parts that help them to be expert swimmers! Each species may have slightly different sizes and shapes to certain body parts. Can you name some of their body parts and spot the differences?

Use the word bank to help you fill in the blanks. We have done the first one for you.

Today, we’re going to have you use your observational skills to learn how to identify the two orca communities from each other. Then we will go into how to identify individual orcas, and individual gray whales.

The graphics below help to explain what methods are used for identification. Once you read through the methods, try your hand at identifying the two orca communities from one another! What type of orca is in photo #1? What type of orca is in photo #2?

Southern Resident orcasBigg’s (Transient) orcas Saddle Patch:Every orca, no matter what community,

has a unique saddle patch—it’s like a human thumbprint!

In the Resident community, there are often members that have “open” saddle

patches, where part of their black skin has crept into the middle of the gray saddle

patch.In the Bigg’s community, there are only a

few cases where any “openness” has occurred. Scaring, or darker lines and rake

marks, is more common in this community, as their prey fights back.

Dorsal Fin:In all orcas: female fin is smaller and typically dolphin-

like; males can have 5’ to 6’ dorsal fins depending upon their size/community they belong to.

In the Resident community, there are often members with a soft, rounded curve to their dorsal fins. Not many members have notches or nicks missing from

their dorsal.In the Bigg’s community, many members have notches and nicks missing, especially in the trailing side of the dorsal (closest to the saddle patch). Their prey fights back, and since the dorsal is made of cartilage, once those pieces are gouged out, they won’t grow back. These markings are often better “field markers” for individual Bigg’s than using their saddle patches for IDs. Also in this community, Bigg’s often have pointy

tips to their dorsal fins that look shark-like.


THURSDAY SALISH SEA WHALES: LEARN BY DOING EDITION

Answers: 1. Southern Resident orca – rounded tip on fin, open saddle patch; 2. Bigg’s orca – pointier tip on dorsal fin, closed saddle patch with scarring marks.

The below graphic helps with field markers to identify individual gray whales.

We’ve also included a photo of a very famous “Sounder” (gray whale that visits Puget Sound in the spring). His name came from a very distinctive mark along his back. Can you guess what his name is? Can you see why we use markings like this to tell individuals apart?

Field Markers:For gray whales, the size and placement of white markings and scars

along the body make each individual unique. Gray whales carry barnacles on them, that when dislodged and fall off, leave this

discoloration. Since these barnacles cluster differently on each animal, the patterns that they leave become unique also.

For this reason, markings on the underside of the tail flukes can be used to identify individual gray whales, as well.

THURSDAY SALISH SEA WHALES: LEARN BY DOING EDITION

Answers: This is #49 Patch! He got his name because of the big, unique white spot along his back. When we see him, we know it’s him!

We hope you’ve had fun becoming familiar with orcas and grays this week using different techniques to learn about them. This wouldn’t be a true “Learn by Doing” if we didn’t include some ways you can help protect these whales from some of the threats they face. *A threat is a source of danger that could harm an individual whale, or a whole population of whales.*

Below we have included two activities that you can print out and do.

As gray whales are bottom feeders, they filter through the mud for ghost shrimp. Sunken plastic can be a threat to them. Plastic is not digested in the stomach and can cause the whale to think he’s full when he’s not. This could

cause starvation, and ultimately, death. Help the gray whale avoid the trash! Place an “X” on the things he should

NOT eat. We’ve done the first one for you.

We hope you’ve had fun becoming familiar with orcas and grays this week using different techniques to learn about them. This wouldn’t be a true “Learn by Doing” if we didn’t include some ways you can help protect these whales from some of the threats they face. *A threat is a source of danger that could harm an individual whale, or a whole population of whales.*

Below we have included two activities that you can print out and do.

Make a pledge! Write a commitment from the suggestions or

create your own! Hang it up where you can see it as a reminder!

PLANT AN OCEAN-FRIENDLY GARDEN.Ocean-friendly plants help trap pollution and keep it from getting into the ocean as “stormwater runoff”. Look up ocean-friendly gardens for more information and inspiration!

STOP USING SINGLE-USE PLASTICS.Request no straws at restaurants, use re-usable water bottles, grocery bags, and containers, use beeswax paper instead of plastic wrap, and buy used toys! It is predicted that by 2050 there will be more plastic in our oceans than fish if we don’t stop using plastic.

Here are some ways that YOU can help!

WALK, BICYCLE, OR RIDE SHARE.Using a car less can help with climate change and can help reduce pollutants from cars.

CONSERVE WATER & ENERGYTurn off the water when you’re brushing your teeth; turn off lights and fans when you’re not in those rooms. Using less water means you’re saving water for rivers, streams, and the sea--helping all who live there!

Here is My Pledge to help orcas:

Southern Resident orcas are being impacted by a lack of their preferred prey, Chinook salmon, pollution, and by underwater noise that makes it hard to communicate with one another and interferes with the echolocation they use to find food. These are only a few

suggestions for things we can do to make changes for the orcas, and we encourage you to brainstorm some of your own ideas, too!

Write a pledge about something you’re going to do to help Southern Resident orcas. The best part? It will help all the other sea creatures, as well.
