All of the AmeriCorps members will be going to one of two conferences this winter. Being the Marine Mammal Stranding Educator, it was already decided that I would attend the Ways of Whales Workshop on Whidby Island. Now that day had finally arrived, so I shot out of bed, quickly threw on my clothes and was ready to go. I met up with my fellow whale enthusiasts, Betsy, Amy, Carolyn, and Sue and we got on our way.

Harbor Porpoise vs. Dall’s Porpoise
A Porpoise is a type of toothed whale or Odontocete Whale. Similar in body shape to dolphins, porpoises are generally smaller, have rounded rostrums and spaded teeth. Additionally, while you will see dolphins swimming in pods, porpoises are less social creatures and will be swimming alone or in small groups.

|
Fun Fact
|
They are considered the fastest swimmers among the small whales. They are capable of reaching speeds of 30 knots (34 MPH) over short distances.

Identifying Dall’s Porpoises and Harbor porpoises can be difficult in the field. While you may not be able to see the color difference, look for the presence or absence of water spray. Because of their speed in the water, Dall’s Porpoises create a stream of water known as a rooster spray. Harbor Porpoises will not.
