							1 - Penguins waddle when they walk - this saves 
							them energy because they are tall with short legs.
							
2 
							- Penguins move fastest on snow and ice by "tobogganing" 
							- they lie on their front and push themselves with their 
							feet, they can go faster than you can run.
							
3 
							- Penguins have strong claws and strong short legs, 
							these grip onto slippery rocks or ice when they come 
							out of the sea.
							
4 
							- Penguins pull their feet in close for streamlining 
							when swimming, like an aircraft pulling in its wheels 
							Penguins can stick a foot out as a water-brake, they 
							can turn and head back where they came in 1/5th of a 
							second.
							
5 
							- Penguin "wings" are adapted to be short, 
							stiff flippers for "flying" in water. 
							The elbow and wrist joints are fixed to give a rigid 
							flipper for swimming underwater.
							
6 
							- Penguins collect air in their feathers by preening 
							especially before going to sea, it insulates against 
							the cold. This trapped air helps the penguin swim at 
							top speed by releasing as tiny bubbles which reduce 
							drag, very useful when escaping predators.
							
7 
							- All penguins apart from King and Emperor penguins 
							build a nest. They are a low pile of stones so if 
							the temperature rises and snow melts, the nest is not 
							flooded. 
							
8 
							- Emperor and King penguin parents keep their egg and 
							then the young chick on their feet, it is covered 
							by a flap of skin called a brood pouch until they are 
							large enough to keep themselves warm.
							
9 
							- Penguins often nest in large colonies which makes 
							it easier to head out to sea together, this helps them 
							fish for food better and avoid predators both in the 
							sea and on land.
							
10 
							- Like other birds, penguins lay eggs which have 
							to be kept warm all the time, the parents take it in 
							turns to look after the egg or go to sea to feed.
							
11 
							- Chicks are fed on the nest by the parents until 
							they are big enough to join a creche for protection 
							against predators, this lets both parents to go to sea 
							at the same time to catch more food.
							
12 
							- Smaller penguins migrate north to escape the hard 
							Antarctic winter, they return in the short summer 
							to make the most of abundant food and rear their chicks.
							
							13 - Emperor penguins form huddles to keep warm in the 
							coldest weather, they take it in turns to be on 
							the outside or in the middle!
							
14 
							- Penguins gather at the ice edge in groups before 
							jumping in the sea. This confuses any predators that 
							might be about and increases each penguins chance of 
							survival.
							
15 
							- During a deep dive, a penguins' heart rate slows 
							from 80-100 down to 20 beats per minute to let them 
							dive for longer.
