0:00:57 > 0:00:59- I saw something incredible.
0:01:00 > 0:01:03- Young hammerhead sharks.
0:01:03 > 0:01:07- Be careful. If they're young, - their parents might be nearby.
0:01:07 > 0:01:11- Hammerhead sharks - don't care for their young.
0:01:11 > 0:01:13- They're left alone from birth.
0:01:14 > 0:01:18- The young stay together - until they're old enough to... Uh?
0:01:20 > 0:01:23- This shark tastes odd.
0:01:25 > 0:01:27- It doesn't sound right.
0:01:27 > 0:01:30- It's difficult to chew.
0:01:30 > 0:01:32- It's not a shark, it's a sub!
0:01:36 > 0:01:38- I haven't finished yet.
0:01:40 > 0:01:41- What's happening?
0:01:42 > 0:01:45- The hammerhead sharks - are learning how to hunt.
0:01:45 > 0:01:49- They're confused, - but at least they weren't hurt.
0:01:51 > 0:01:52- Back you go.
0:01:57 > 0:02:00- This should be far enough - for me to study them.
0:02:02 > 0:02:06- Jumping jellyfish! The sharks - have all left the lagoon.
0:02:10 > 0:02:13- I must follow them.
0:02:16 > 0:02:19- They seem to be in a hurry.
0:02:19 > 0:02:21- It's getting darker.
0:02:22 > 0:02:23- You know what that means.
0:02:24 > 0:02:26- We hunt at night.
0:02:27 > 0:02:29- Ready? Go.
0:02:30 > 0:02:31- Oh, no, which way?
0:02:52 > 0:02:55- I must get out before the sharks...
0:02:56 > 0:02:58- ..disappear.
0:02:58 > 0:03:00- Cregynog, calling Cregynog.
0:03:01 > 0:03:05- You'll never believe it - but I've just crashed the sub.
0:03:05 > 0:03:06- Again?
0:03:06 > 0:03:08- Again?- - I can't follow the sharks.
0:03:08 > 0:03:10- I need help.
0:03:10 > 0:03:12- We've lost the connection.
0:03:12 > 0:03:14- We've lost the connection.- - Sound the octo-alert.
0:03:16 > 0:03:18- To the diving bay.
0:03:26 > 0:03:29- Cregynog's had an accident.
0:03:30 > 0:03:31- Again?
0:03:31 > 0:03:35- He was following three sharks. - We must help him.
0:03:35 > 0:03:42- He was heading for the open water. - It's a dangerous place for sharks.
0:03:42 > 0:03:44- We'd better hurry.
0:03:49 > 0:03:51- Cregynog. Are you OK?
0:03:51 > 0:03:54- Cregynog. Are you OK?- - I am, but the sharks have gone.
0:03:54 > 0:03:57- We must split up to search for them.
0:03:57 > 0:04:02- Search for a hammerhead shark? - This will be easy.
0:04:02 > 0:04:07- Don't follow them too closely. - They're easily confused.
0:04:07 > 0:04:11- OK. Cregynog, come with me. - Let's do this.
0:04:16 > 0:04:19- No sign of any hammerhead sharks.
0:04:20 > 0:04:23- Cregynog, I think I see one.
0:04:23 > 0:04:25- Don't let him out of your sight.
0:04:26 > 0:04:30- That shouldn't be difficult. - He's just sniffing the sand.
0:04:32 > 0:04:36- I can't see you, shark, - but I can smell you.
0:04:37 > 0:04:40- Yes - smell this!
0:04:42 > 0:04:46- Oh, no, - the shark's been stung by a ray.
0:04:46 > 0:04:49- A ray's sting isn't harmful - to a shark.
0:04:51 > 0:04:53- That won't stop me.
0:04:54 > 0:04:57- No? How about them? After him, lads.
0:05:01 > 0:05:03- Oh, dear. I must help him.
0:05:09 > 0:05:12- Hello. Don't be scared. - I'm a doctor.
0:05:12 > 0:05:15- I'm here to remove these spikes.
0:05:19 > 0:05:22- One. Plenty to go-o-o-o!
0:05:24 > 0:05:26- Come here, sharky.
0:05:27 > 0:05:28- A-ha!
0:05:28 > 0:05:31- Chasing an octopus.
0:05:33 > 0:05:34- Just where I want you.
0:05:37 > 0:05:39- To be honest, I caught you.
0:05:41 > 0:05:43- Let me go, octopus.
0:05:43 > 0:05:47- I can't follow that shark - if the octopus catches it.
0:05:48 > 0:05:49- I know!
0:05:52 > 0:05:54- A striped shark!
0:05:55 > 0:05:58- My camouflage worked!
0:05:59 > 0:06:01- The octopus thought I was a...
0:06:01 > 0:06:02- The octopus thought I was a...- - Striped shark.
0:06:03 > 0:06:06- Wait! - I'm not really a striped shark.
0:06:08 > 0:06:11- These young sharks - are easily confused!
0:06:11 > 0:06:15- Harri to Cregynog. - I'm following one of the sharks.
0:06:15 > 0:06:17- It's a lively one.
0:06:18 > 0:06:20- Good work, Harri.
0:06:20 > 0:06:23- That's two - only one to go.
0:06:25 > 0:06:29- Hey, I can smell food. Where is it?
0:06:32 > 0:06:34- You can't run away from me.
0:06:34 > 0:06:36- Where did you go?
0:06:37 > 0:06:39- Uh-oh. My head's stuck.
0:06:42 > 0:06:45- Hey, someone. Help.
0:06:46 > 0:06:47- Down there.
0:06:48 > 0:06:49- The third shark.
0:06:49 > 0:06:51- It's stuck.
0:06:55 > 0:06:57- We are Octonots. We're here to help.
0:06:58 > 0:06:59- He's stuck.
0:07:00 > 0:07:01- We'll call for help.
0:07:02 > 0:07:05- There we go, the last spike.
0:07:05 > 0:07:08- Calling Pegwn and Harri. - We have the third shark.
0:07:09 > 0:07:11- Its head is stuck.
0:07:11 > 0:07:13- Stuck? We must help my brother.
0:07:13 > 0:07:15- On our way, Captain.
0:07:19 > 0:07:22- Come on, our brother's in trouble.
0:07:27 > 0:07:31- Ahoy, Pegwn, these sharks are fast!
0:07:32 > 0:07:34- You're telling me.
0:07:37 > 0:07:39- Pegwn, Harri, over here.
0:07:43 > 0:07:44- This isn't nice!
0:07:45 > 0:07:48- Some grease might help dislodge - his head.
0:07:49 > 0:07:51- Good idea. Grab a fin each.
0:07:51 > 0:07:52- There we go.
0:07:54 > 0:07:58- Don't worry, - we'll get you out in no time.
0:07:58 > 0:08:02- Pull after three. - Ready? One, two, three.
0:08:02 > 0:08:05- Hey, look behind me.
0:08:05 > 0:08:10- Incredible. Hammerheads can see - what's behind them.
0:08:12 > 0:08:13- Shark!
0:08:15 > 0:08:17- This should give him - food for thought.
0:08:22 > 0:08:25- They don't taste very nice.
0:08:26 > 0:08:28- You'd taste much better.
0:08:31 > 0:08:33- You'll never catch me.
0:08:35 > 0:08:39- Pegwn, - follow me and bring your friend.
0:08:40 > 0:08:42- Harri, keep that shark busy.
0:08:42 > 0:08:45- Over here, you ugly little shark.
0:08:45 > 0:08:48- Hey, what? Tell them!
0:08:49 > 0:08:52- We have something tasty for you.
0:08:55 > 0:08:56- Now!
0:08:56 > 0:08:59- Retreat, everyone.
0:09:01 > 0:09:02- What are you doing?
0:09:02 > 0:09:04- What are you doing?- - Leave us be.
0:09:05 > 0:09:07- Uh-oh.
0:09:12 > 0:09:14- He got the message!
0:09:14 > 0:09:16- That was fun.
0:09:17 > 0:09:19- Well done.
0:09:19 > 0:09:21- Hey, you, don't forget me.
0:09:21 > 0:09:23- Hey, you, don't forget me.- - Sorry about that.
0:09:23 > 0:09:25- Ready? Pull.
0:09:25 > 0:09:27- Pull.
0:09:31 > 0:09:32- We did it.
0:09:32 > 0:09:34- Thanks.
0:09:34 > 0:09:36- Thank you for your help.
0:09:36 > 0:09:38- Thank you for your help.- - Not that we needed it.
0:09:38 > 0:09:42- It's time for us to go. - See you again.
0:09:42 > 0:09:45- Wait. Where are you going?
0:09:45 > 0:09:47- Follow us and we'll show you.
0:09:47 > 0:09:50- What are we waiting for? Come on.
0:09:54 > 0:09:58- We're in the open sea - nothing - to see for hundreds of miles.
0:09:59 > 0:10:00- Where could they be going?
0:10:00 > 0:10:02- Where could they be going?- - There's something ahead.
0:10:03 > 0:10:04- It's big.
0:10:05 > 0:10:07- A sea mountain.
0:10:07 > 0:10:12- It's not on our maps. We must - be the first to discover it.
0:10:13 > 0:10:16- I think the hammerhead sharks - beat us to it. Look!
0:10:20 > 0:10:22- That's where they went.
0:10:22 > 0:10:25- They rest here during the day - when they're not hunting.
0:10:26 > 0:10:28- Cheerio!
0:10:28 > 0:10:30- Take care.
0:10:30 > 0:10:31- Take care.- - Good luck.
0:10:35 > 0:10:37- Hey, look, a ray.
0:10:37 > 0:10:41- It's not a ray, it's a sub!
0:10:58 > 0:10:58- .
