Details

Jeff Peneston: "The seal’s ancestors lived on land and you can see that the flipper has five fingers that each end in a claw. The claws look very much like those of dogs, and like dogs, the seal uses them to scratch himself as well as to help climb onto the ice. The seal’s flipper also contains the same three bones that are in a human arm. The seal’s arm bones are shorter and the fingers and hands have become elongated and webbed with skin to form the flipper." On the sea ice, near the icebreaker Oden.

Being a scientist really appealed to me because I was really excited about the opportunity to be curious about the world and to try to answer questions that interested me about the natural world.

One of the most rewarding things about being a scientist is the discovery of new knowledge. You get to go out and ask questions that nobody has asked before, use your imagination to see the world around you and become excited about discovering new knowledge and new ideas.
