1
00:00:01,199 --> 00:00:15,359
what do fish look like we live on land and we are surrounded by air and they live in water they are

2
00:00:15,359 --> 00:00:26,980
fish there is a wide variety of fish in multiple colors and different shapes but what do they all

3
00:00:26,980 --> 00:00:33,039
have in common and how are they similar and different from us we will choose a

4
00:00:33,039 --> 00:00:41,380
gilt-haired bream and a red mullet to find out materials a fish gilt-haired

5
00:00:41,380 --> 00:00:53,140
bream red mullet kitchen board rubber gloves knife their bodies are perfectly

6
00:00:53,140 --> 00:01:04,549
adapted to live underwater while you have skin and hair fish are covered in scales that isolate them

7
00:01:04,549 --> 00:01:15,879
and protect them like a raincoat look at the head their eyes and mouth stand out the mouth

8
00:01:15,879 --> 00:01:24,760
shows a set of sharp teeth humans breathe through lungs but our gilthead bream how does it breathe

9
00:01:24,760 --> 00:01:35,920
can you see the openings on its sides inside are the gills fish use gills for breathing thanks to

10
00:01:35,920 --> 00:01:45,280
them they can absorb all the oxygen dissolved in the water and how do fish move no matter how good

11
00:01:45,280 --> 00:01:53,379
you are at swimming you will never swim like a fish for propulsion fish use a powerful tail

12
00:01:53,379 --> 00:02:06,599
that ends in the caudal fin they use the other fins for stability now let's have a look at a

13
00:02:06,599 --> 00:02:14,900
fish inside if we pull its muscles apart we find out that like us they have a skeleton made of a

14
00:02:14,900 --> 00:02:25,340
spinal column and bones similar to our ribs if we do the same with the red mullet we will find out

15
00:02:25,340 --> 00:02:32,900
that they are very similar inside the skeleton provides them with a frame and protects internal

16
00:02:32,900 --> 00:02:41,960
organs each of these bones is a vertebra that is why the animals that have it are called vertebrates

17
00:02:41,960 --> 00:02:58,479
Fish reproduce through eggs. They are aviparous, like reptiles, birds, and amphibia. On the other

18
00:02:58,479 --> 00:03:07,539
hand, mammals are viviparous. To sum up, fish have vertebrae, therefore they are vertebrates.

19
00:03:07,539 --> 00:03:10,539
Their body is covered in scales.

20
00:03:10,539 --> 00:03:13,539
They have fin-shaped extremities.

21
00:03:13,539 --> 00:03:16,539
They breathe through gills.

22
00:03:16,539 --> 00:03:19,539
They are aviparous.
