00:03 Good evening, Kapuso!
00:05 I am your brother, Kim, who will give you trivia behind the trending news.
00:09 There are many people who got lost in the explanation of the water in a beach in Capiz.
00:13 Why did this happen?
00:15 We will give you an explanation.

00:21 Shane even caught the student's eye while walking in the middle of a beach in Rojas City, Capiz this weekend.

00:28 The water in the sea turned blue.
00:31 It was really blue.
00:32 I thought it was street lights or just a moon.
00:35 I got closer and I captured it with my cellphone.
00:38 I was really amazed because it was the first time I saw it.
00:41 The light of the water in Capiz can be explained by science.
00:45 Because it is in organisms that are called bioluminescent organisms.
00:49 [music]
00:52 Brother Kim, how can a living organism turn blue?
00:56 Brother Kim, what now?
01:00 Bioluminescence is the light that comes out of a living organism.
01:04 It happens because of a chemical reaction.
01:06 Two chemicals are needed to produce bioluminescence.
01:09 The first is luciferin and the second is luciferase.
01:12 This is a cold light.
01:14 It means that less than 20% of it generates thermal energy or heat.
01:18 Bioluminescence serves various purposes.
01:20 It acts as a defense mechanism.
01:22 It is used for attracting mates or also for luring prey.
01:25 It can also be used to communicate with other organisms.
01:28 Most bioluminescent creatures are found in the ocean.
01:31 Some of them are fish, jellies, and bacteria.
01:34 In the case of the light of the sea in Roa City,
01:36 The one that you see there in the ocean is not actually just limited to us.
01:40 There are a lot of organisms.
01:42 So unless you're going to take that particular water sample and really identify the main cause.
01:47 But the most common one that produces bioluminescence are often produced by planktonic dinoflagellates.
01:53 So these are single-celled organisms that are called protists.
01:56 I was amazed by the nature.
01:58 I thought I would only see it in other places, but here, I can see it.
02:02 When we were praying last night, I saw it too.
02:04 We can't see anything that's supposedly glowing.
02:08 In Pilar Campus, it's every night.
02:10 But did you know that not only in the ocean, there are bioluminescent organisms,
02:13 there are also on the ground.
02:15 One of them was the cover of an award-winning Kapuso film.

02:23 The planktonic dinoflagellates are probably one of the most popular bioluminescent organisms on Earth.
02:29 Like other bioluminescent marine species,
02:31 the light that comes from planktonic dinoflagellates is also due to the chemical reaction that happens inside their bodies.
02:37 Aside from using their light as a defense against predators,
02:41 most planktonic dinoflagellates use their light to find a mate.
02:46 Meanwhile, for more news, tweet or comment #KuyaKim, what's next?
02:52 Always remember, it's important to know.
02:55 I'm Kuya Kim and I'll see you in 24 hours.
