0:00:35 > 0:00:38ALL: It's our planet!
0:00:42 > 0:00:45This is a shrew.
0:00:48 > 0:00:51It's really small.
0:00:51 > 0:00:57It's as small as a mouse and can run really fast.
0:01:01 > 0:01:06While a shrew is very small,
0:01:06 > 0:01:10an elephant is really big.
0:01:10 > 0:01:18Even a baby elephant is much bigger than a shrew.
0:01:18 > 0:01:25Really small animals have to look out for those really big feet.
0:01:28 > 0:01:33This is a flounder, and it lives in the sea.
0:01:33 > 0:01:36It's really thin.
0:01:40 > 0:01:47It's so thin, it can lie on the sand and hardly anyone can spot it.
0:01:54 > 0:01:58You can only see it when it wiggles its eyes,
0:01:58 > 0:02:01or flaps its fins.
0:02:03 > 0:02:06While the flounder is thin...
0:02:06 > 0:02:10the whale is fat.
0:02:10 > 0:02:16It has a big, round belly and has to eat lots of food every day.
0:02:26 > 0:02:30It likes to make great splashes with its tail.
0:02:31 > 0:02:34It's a great swimmer.
0:02:41 > 0:02:44This is a tortoise.
0:02:44 > 0:02:48And it's really slow.
0:02:50 > 0:02:55It has to carry its shell around with it all day.
0:02:55 > 0:02:59It takes its time doing everything.
0:03:04 > 0:03:08While a tortoise is really slow...
0:03:08 > 0:03:15a cheetah is really fast. It's super fast!
0:03:15 > 0:03:19It can beat any animal in a race.
0:03:21 > 0:03:25It has to be fast to catch its supper.
0:03:30 > 0:03:34This is a giraffe, and it's really tall.
0:03:34 > 0:03:38It has the longest neck of all...
0:03:39 > 0:03:43..and very long legs!
0:03:50 > 0:03:58It's so tall, it can reach the tops of trees for a nice, leafy lunch.
0:03:58 > 0:04:03While a giraffe is tall...
0:04:03 > 0:04:06a warthog is short.
0:04:06 > 0:04:11It's legs aren't as long as a giraffe's.
0:04:11 > 0:04:15It can't even reach to have a scratch, unless it uses a rock.
0:04:15 > 0:04:19Warthogs love to scratch.
0:04:22 > 0:04:24Big...
0:04:24 > 0:04:26small!
0:04:26 > 0:04:28Short...
0:04:28 > 0:04:30tall!
0:04:30 > 0:04:33Fat...
0:04:33 > 0:04:35thin.
0:04:35 > 0:04:37Fast...and
0:04:37 > 0:04:40slow!
0:04:40 > 0:04:43CHILDREN: It's our planet.
0:04:45 > 0:04:50SHE BARKS I'm a barking dog!
0:04:50 > 0:04:52Can you be an animal too?
0:04:52 > 0:04:54SHE BARKS
0:04:54 > 0:04:58What animal is this?
0:04:59 > 0:05:02It's a tortoise.
0:05:04 > 0:05:09And Izzy is a rabbit.
0:05:11 > 0:05:14CHILDREN: It's our planet!
0:05:19 > 0:05:22This lion mum is feeding her young.
0:05:22 > 0:05:25Feeding is very important for baby animals
0:05:25 > 0:05:29because it makes them grow up big and strong.
0:05:29 > 0:05:34Lots of animal mums make milk which their babies suck on.
0:05:34 > 0:05:38These are meerkats
0:05:38 > 0:05:43and there are the babies enjoying a tasty drink of their mother's milk.
0:05:46 > 0:05:49What a lot of hungry mouths to feed.
0:06:00 > 0:06:06Did you know that dolphins also suckle milk from their mum?
0:06:06 > 0:06:13The baby needs to swim on its back whilst the mum squirts the milk into its mouth.
0:06:18 > 0:06:21Baby birds don't drink milk,
0:06:21 > 0:06:25instead their parents collect food for them.
0:06:25 > 0:06:32These hungry chicks are eating some juicy caterpillars - like this one.
0:06:32 > 0:06:37BIRDSONG
0:06:44 > 0:06:48This is a flycatcher.
0:06:48 > 0:06:54A flycatcher's chicks love eating flies as well as caterpillars.
0:06:54 > 0:06:58Before these chicks grow up and leave their nest,
0:06:58 > 0:07:01they'll eat thousands of caterpillars.
0:07:02 > 0:07:08Collecting food keeps Mum and Dad very busy.
0:07:09 > 0:07:13This pelican is diving for fish.
0:07:15 > 0:07:18Got one!
0:07:22 > 0:07:26Pelicans carry fish back to their chicks.
0:07:28 > 0:07:32To feed their young the parents must open their mouths
0:07:32 > 0:07:39so that the chicks can reach way down their throats for the fish.
0:07:39 > 0:07:42This bird is a tern.
0:07:42 > 0:07:48Whilst Dad has been busy fishing, Mum's been looking after the chick.
0:08:02 > 0:08:05This kingfisher chick is hungry...
0:08:21 > 0:08:24..and gets fish for its dinner.
0:08:34 > 0:08:36The baby kingfisher will need some more though.
0:08:36 > 0:08:41A growing chick needs to eat more than 12 fish in one day.
0:08:44 > 0:08:50Baby animals need lots of food to grow up big and strong.
