00:00:02,669 --> 00:00:15,669
In the animal kingdom, there are two groups, invertebrates or invertebrates.

2
00:00:15,669 --> 00:00:19,670

Invertebrates are two groups, mollusks and arthropods.

4
00:00:25,670 --> 00:00:28,670
What is the difference?

5
00:00:28,670 --> 00:00:43,229
The mollusks are viperous, they lack slugs, they don't have legs, they have a soft body,

6
00:00:43,229 --> 00:00:52,229
they can have a shell or tentacles, they can live in water or land.

7
00:00:52,229 --> 00:00:56,189
These are examples of mollusks.

00:00:56,969 --> 00:01:01,950
Slug, mussel, octopus, squid, clam and snail.

9
00:01:03,189 --> 00:01:04,150
Arthropods.

10

00:01:25,750 --> 00:01:28,150
They can live in land and in water.

16
00:01:29,030 --> 00:01:31,730
These are examples of octopus.

The animals can be two vector baits.

20
00:01:46,049 --> 00:01:48,310
Who belongs to vector baits?

21
00:01:48,890 --> 00:01:49,709
So easy!

22
00:01:49,709 --> 00:01:56,010
