Vídeo explicativo de los peces para Natural Science, en inglés y castellano.
Hello, hello again, my friends. How are you? I'm here again. Okay, this time to talk about fish. Okay, so I'm going to give you some characteristics of that all fish have in common.
00:00:02
Remember that when we saw animals, when we studied animals, there are some animals that live in the water that can swim, but they are mammals, ok?
00:00:19
Like whales, like dolphins, they are not fish, ok?
00:00:32
So, in this case, we are going to talk about fish.
00:00:39
¿Qué tal chicos? Aquí estoy otra vez en esta ocasión para hablar de peces.
00:00:43
Remember that before we started, when we were looking at the mammals, there were some mammals that could swim, but they were not fish.
00:00:47
In this case, we were talking about whales, we were talking about dolphins, for example.
00:01:01
Well, now we are going to see fish and what are the characteristics of the fish.
00:01:07
Let's go!
00:01:12
So, as the rest of groups are, are we, we are, we are studying, fish are vertebrates, okay?
00:01:14
Repeat, please.
00:01:25
Fish are vertebrates, okay?
00:01:27
As you can see in the picture, okay?
00:01:32
In the shadow, they have, they have a skeleton inside their bodies, okay?
00:01:34
Bueno, pues no mucho más que comentar.
00:01:42
It's just that the fish are also vertebrates, like the rest of the animals that we've seen so far, okay?
00:01:45
Because they have an internal skeleton.
00:01:53
Fish are oviparous.
00:01:57
Repeat, please.
00:02:00
Fish are oviparous.
00:02:02
Okay.
00:02:08
They're very completely different, these eggs, than the bird's eggs or reptile's eggs, okay?
00:02:10
they are very small and the mummy in this case, okay, the female fish leave a lot of eggs,
00:02:17
maybe sometimes in the water, sometimes on their body, okay, and they leave a lot at once,
00:02:26
okay, and little fish when they can live by themselves they hatch from these eggs, okay,
00:02:41
but they are very very small well because the birds are oviparous and nothing is on this occasion they are
00:02:48
very different from the eggs of the birds or the eggs of the reptiles because they are much
00:02:56
smaller they do not have a shell let's say hard then well they leave them in the water they leave a
00:03:04
montón cada vez. Y cuando está el pececito preparado para vivir por sí mismo, pues, pues nada, ¿vale?
00:03:12
Next. Fish have got fins. Repeat please. Fish have got fins. Ok, we learned this word in a previous
00:03:19
unit when we talk about adaptations okay in this case fins is a body adaptation that fish have
00:03:38
okay because they need to swim is the way is moving these fins and moving the tail that we
00:03:45
see later okay they can swim so these fins they have some of them on their body could be bigger
00:03:53
could be smaller it depends ok so they use it to swim
00:04:04
well fins is fins some previous unit because we saw that
00:04:11
one of the adaptations of this word we already learned it when we saw the
00:04:19
adaptations of animals and fins because it is an adaptation that
00:04:23
the fish have to be able to swim as you see in the example because they have
00:04:27
different different types of fins in your body is worth to be able to advance in the in the
00:04:32
water moving them even with the tail that is what we are going to see someone remembers how to say
00:04:39
tail in English
00:04:47
Yes, tail. That's right. Very good. So, fish have got a tail. Okay. Repeat, please. Fish have got a tail. Nice.
00:04:48
Okay. So, tail in this case, so help to move. That's it. This is the function that it has. Okay. So, nothing is to say.
00:05:04
Bueno, pues los peces tienen cola.
00:05:13
En este caso, pues les ayuda también a moverse dentro del agua.
00:05:15
Tampoco tiene mucho más.
00:05:18
Fish have got scales.
00:05:23
Repeat, please.
00:05:26
Fish have got scales.
00:05:27
Okay, so scales is the way that their skin is covered.
00:05:34
It's like there are scales similar than reptiles as we saw last week.
00:05:39
so as you can see in the picture this scale so that has they have this form okay you can see
00:05:45
maybe when you when you buy fish okay to eat at home okay you can you can see the skin of their
00:05:54
of the fish you eat you can see too well because the skin is covered with scales
00:06:00
it has that shape as you can see there it is very similar to the skin of reptiles the only thing is
00:06:07
And the last characteristic is that fish can swim and they can breathe in the water, okay?
00:06:14
So, repeat after me, fish can swim, because they live under the water, so they need to move to eat, they move to go to anywhere, okay?
00:06:33
so for that reason they they swim so this is the the way they moving okay
00:06:49
bueno pues los peces pues nalan vale pueden nadar vale es la forma que que
00:06:54
tienen ellos de moverse debajo del agua para ir a comer para ir a donde necesiten
00:07:00
okay and this is the the end of this presentation the end of this video i hope
00:07:06

00:07:13
video that maybe is funnier than me okay but but I'm very glad to to record this video for you okay
00:07:20
It's true that it's more fun and cooler than this one, but I'm excited to record it for you, okay?
