Dolphins use a technique called echolocation, also referred to as sonar, to locate food and navigate around the ocean.

There are around 32 species of ocean dolphins. Today we’re going to learn about bottlenose dolphins and striped dolphins.

Bottlenose dolphins are the most common and well-known of all the types of dolphins. They weigh 440 to 600 pounds and are around 10 feet long. Images found at http://www.bottlenose-dolphin.info/picture.php

They prefer warm to tropical water, but they can be found in the Pacific and Atlantic Oceans as well. Point to locations that bottlenose dolphins would be found.

There are two types of whales, toothed whales and baleen whales. The diagram below shows all the different parts of a typical toothed whale. Image found at http://www.newfoundlandwhales.net/images/tootheddraw.jpg

Today we’re going to discuss an example of a toothed whale and of a baleen whale. First we’re going to learn about a type of toothed whale: the Orca or Killer whale.

The Orca or killer whale belongs to the family of dolphins. They grow to be about 27 to 33 feet long and weigh 8,000 to 12,000 pounds. Their skin is mostly black with white patches.

Orcas eat a variety of different fish, squid, sharks, and other marine mammals. They can swim very fast to catch their prey.

Orcas live together in groups called pods. They hunt together and protect their young and sick. Image found at http://www.kayakingtours.com/Images/JSE_main_4.jpg

Let’s practice what we’ve learned about Orca whales!

Orcas are very small and only weigh 3,000 to 5,000 pounds. TRUE FALSE

Oops! Remember that Orcas are large and weigh 8,000 to 12,000 pounds!

That’s right! Orcas weigh 8,000 to 12,000 pounds. Keep up the excellent work!

Now that we’ve learned about Orcas or killer whales, let’s learn about a type of baleen whale…….. The Blue Whale!!

The blue whale is the largest and loudest animal on Earth. They are around 80 feet long and weigh 120 tons!! Their whistle can be heard for hundreds of miles.

They eat very tiny organisms, like krill, plankton, and other small fish. They will eat around 2,000 to 9,000 pounds of plankton each day!

Blue whales can be found in all the oceans and often swim alone, in pairs, or in small groups.

Blue whales are the loudest animals on Earth. TRUE FALSE

Oops! Remember blue whales are the loudest animals and their whistle can be heard for hundreds of miles. You’re ready to take the quiz

Terrific! Blue whales have a whistle that could be heard for hundreds of miles. You’re ready to take the quiz
