00:00Why?
00:02I'm sorry.
00:04You're still here.
00:06I'm just practicing my new line in AHA.
00:10The...
00:12Why?
00:14Starting today, our why's will be answered here in AHA's Why List.
00:23Do you know why animals are so popular in the world?
00:26Because of their abilities.
00:28Just like the orca behind me.
00:34In a part of the ocean of Misamis Occidental,
00:37there's an amazing sea creature that was spotted.
00:44This amazing encounter
00:46was captured by a video of our neighbor.
00:53Our neighbor, Kevin Soho, is on his way home.
00:56His fellow fishermen noticed a huge sea creature.
01:03They thought it was a dolphin,
01:06but it was actually a seal.
01:09The seal was so happy
01:11that it changed its mind
01:12because the animal they saw wasn't a dolphin,
01:15but a...
01:18Orca.
01:21Or Killer Whale.
01:23And it's not just one,
01:24but a whole group.
01:26We saw a big one.
01:30There were two or three under it.
01:34It was huge.
01:35It was bigger than our boat.
01:37What type of animal is this?
01:39Dolphin or Whale?
01:41Orcas are called Killer Whale.
01:43Did you know that this is a type of dolphin?
01:46In fact, this is the biggest dolphin.
01:49Orcas can grow from 23 to 32 feet
01:52or almost the size of a bus.
01:54Wow!
01:55But why is it called Killer Whale?
02:00Did you know that ancient sailors
02:02gave the name Killer Whale to the orcas?
02:05According to their observations,
02:07the group of orcas catches
02:09or hunts larger species of whales.
02:12Because of this,
02:13they called these whales
02:15Whale Killer,
02:17which was later reversed
02:19and became Killer Whale.
02:21But don't worry,
02:22no one should be afraid
02:24of encountering a Killer Whale
02:26because it doesn't eat humans.
02:29I mean,
02:30it doesn't eat us.
02:32It only eats fish,
02:34penguins,
02:35and other marine mammals like sea lions.
02:37Killer Whales shouldn't be afraid of them.
02:41But here,
02:42you might be afraid of
02:44the Dragon of the Sea.
02:52Skinny skin,
02:56long tail,
02:58and squinting eyes.
03:01This is the Philippine Sailfin Dragon.
03:04Others say
03:05it looks like the fictional monster
03:09Godzilla.
03:10Hmm, it could be.
03:11But the truth is,
03:12these are harmless
03:13and they only grow from 2 to 4 feet.
03:15Male Sailfin Dragons have a tail like this.
03:18And this is where they got the name Sailfin.
03:21Female Sailfin Dragons
03:23have a smaller head
03:24compared to males.
03:26These are water-loving.
03:29They have padded foot
03:31or flat feet
03:32to help them walk
03:33on the water.
03:35They usually go to the water
03:37to escape their predators.
03:39Speaking of predators,
03:41they also have superpowers
03:43that they can detect
03:44if there's a predator nearby.
03:46They have a parietal eye
03:48that serves as their third eye.
03:50And it's placed above their head.
03:53They'll know if there's a predator nearby
03:55if their light source is blocked.
03:59According to the International Union for Conservation of Nature
04:02or IUCN,
04:03the Philippine Sailfin Dragon
04:05is on the Red List of Threatened Species.
04:07This means that
04:08these are vulnerable or high-risk
04:10in the wild.
04:11So to not lose them,
04:12they should be protected.
04:13Here it is.
04:17Did you know that
04:18more than 500 million years ago,
04:20new life forms were still floating in the sea?
04:24And among them,
04:25there were octopuses.
04:26Predators used to be huge.
04:28That's why sea creatures like octopuses
04:31need to develop
04:32a defense against them.
04:34And one of these
04:35is the creation of shells.
04:37Inside their bodies,
04:38that's octocool.
04:40In these shells,
04:42there's a small crack between their flesh.
04:44And when they extract liquid
04:46from these cracks,
04:47they replace it with gas
04:49so that they can cook.
04:51But because of evolution,
04:52other skills were developed in the octopuses.
04:56Such as moving fast,
04:59ability to squeeze into tighter places,
05:01and the release of dark ink
05:03to distract their predators.
05:06But because of their new survival strategies,
05:08their shells are gradually not being used.
05:12And through time,
05:13these octopuses are getting smaller and smaller.
05:15The old octopuses
05:17can no longer keep up
05:18with the younger ones.
05:20That's why eventually,
05:21the octopuses with internal hard shells
05:23also became extinct.
05:26According to scientists
05:27in the University of Bristol in the UK,
05:30we can see in the fossils of the octopuses
05:32that they stopped having internal shells
05:35around 200 billion years ago.
05:37Now, that's during the Jurassic Age!
05:41Alright, we've answered your questions, guys.
05:44See you next week!
05:46Amazing, right?
05:47They're really amazing ocean creatures!
06:10Thanks for watching!
