This document summarizes information about dolphins. It discusses where dolphins live (in oceans and some rivers around the world), what they eat (different species eat fish and squid depending on their habitat), and the family structure of dolphins (males are called bulls, females are called cows, and babies are called calves). It also provides three interesting facts: dolphins are born with hair, they evolved from land animals, and they get water from their food, not extra water. The document notes there are 32 oceanic dolphin species and 5 river dolphin species and provides examples. It concludes by identifying the largest oceanic dolphin species.

6. Three Interesting Facts About Dolphins…

7. 1a. Dolphins are Born with Hair
A few hairs on the side of the rostrum (beak). These fall out within
the first week. We think they have hair because…

8. 1b. They Were Once Land Animals
 How do we know?
 By looking at fossils
They lived on land about 50
million years ago.
Scientists believe that they
fished in shallow waters and
after they moved into the
water they stopped needing
legs and started needing fins.
Evolution took care of that.

9. 2. Dolphins Get Water from Their Food
 The fish and squid that dolphins enjoy eating most
have large amounts of water in them and dolphins get
it from eating them. Dolphins do not need any extra
water because they do not sweat like we do.

10. 3. Different Species
We all recognize the Bottlenose dolphin.
There are actually 32 species of oceanic dolphins! There
are also 5 species of dolphins living in rivers.
Atlantic Spotted Dolphin & White Sided Dolphin are both found in
the North Atlantic Ocean. Hector’s Dolphin –
Found in New Zealand

11. More Dolphins…
Most river dolphins are blind, except for the pink dolphin. River dolphins have
something that looks like fingers on the tips of their flippers.
Pink River Dolphin –
Found in the Amazon rivers
in South America Chinese (Yangzte) River Dolphin
