Q7: Answer the following Questions.

How do the following animals move?
(a) Turtles
(b) Penguins
Ans:
(a) Turtles: Turtles move in a unique way, primarily using their legs and feet. They are well adapted for life in both water and on land. In water, turtles use their flippers to paddle and swim gracefully through the water. They move these flippers in a way that resembles the motion of a bird's wings, but with a more sweeping motion. Turtles are strong swimmers and can cover long distances in the water.
On land, turtles walk slowly and steadily using their strong legs. They tuck their head and limbs into their shell and use their abdominal muscles to push themselves forward. This walking movement is generally slow and deliberate.
(b) Penguins: Penguins are flightless birds that have adapted to life in the water. They are excellent swimmers and use their wings, which have evolved into flippers, to propel themselves through the water. Penguins have a unique swimming style called "fly-and-propel." They use their flippers to "fly" through the water and then use their feet and tail to "propel" themselves further. This combination of wing and foot movements allows them to be agile and efficient swimmers.
