hi everyone welcome to our lesson 2 about invertebrates there are six
00:00:04
groups of invertebrates but in this video we are going to practice two
00:00:14
groups the arthropods and the mollusks mirror word arthropods mollusks so these
00:00:23
are the other groups okay let's start with group one arthropods arthropods have a segmented body
00:00:45
and limbs arthropods have an exhaust skeleton it is an external protection or armor
00:01:04
Mirror word, group one, arthropods.
00:01:18
Arthropods have a segmented body and limbs.
00:01:29
Arthropods have an exoskeleton.
00:01:42
It is an external protection or armor.
00:01:47
Arthropods, one.
00:02:01
Insects.
00:02:04
Insects, like bees, are arthropods.
00:02:08

00:02:14
They have thorax.
00:02:18
they have abdomen they have six legs six legs
00:02:21
two antenna antenna yeah and wings
00:02:31
mirror word arthropods one insects
00:02:40
Insects, like bees, are arthropods.
00:02:49
They have head, they have thorax, they have abdomen, they have six legs, and two antennae.
00:02:57
Arthropods too. Arachnids. Arachnids, like spiders, are arthropods. They have head and
00:03:22
thorax. They have abdomen. They have eight legs. Mirror word. Arthropods. Two. Arachnids.
00:03:37
Arachnids, like spiders, are arthropods.
00:03:58
One, they have head and thorax.
00:04:07
Two, they have abdomen.
00:04:14
Three, they have eight legs.
00:04:19
Arthropods
00:04:24
Three
00:04:31
Crustaceans
00:04:32
Crustaceans
00:04:34
Like crabs
00:04:37
Are arthropods
00:04:38
Number one
00:04:42
They have two eyes

00:04:55
Four. Eight. Legs. Five. Carapace or shell. Mirror word. Arthropods. Arthropods. Three.
00:04:57
Crustaceans. Crustaceans, like crabs, are arthropods. They have two eyes, four antennae, two claws, eight legs, and carapace, or shell.
00:05:18
Arthropods 4. Myriapods. Myriapods, like centipedes, are arthropods. They have two antennae, segments,
00:05:52
POTS OF LEGS
00:06:18
Mirror word
00:06:25
Arthropods for
00:06:27
Myriapods
00:06:30
Myriapods, like centipedes,
00:06:32
are arthropods.
00:06:37
Two antenna
00:06:41
segments body and lots of legs
00:06:45
group two mollusks mollusks have a soft body some mollusk like slugs or snail have a shell
00:07:00
for protection other mollusks like octopuses have tentacles mirrored mollusks have a soft
00:07:22
body. Some mollusks like slugs or snail have a shell for protection. Other
00:07:45
mollusks like octopuses have tentacles okay let's see more descriptions about
00:08:03
group two mollusks mollusk have soft so gastropods cephalopods and bivalves
00:08:18
So, for gastropods, they have two antennae with eyes.
00:08:36
Some have a shell for protection.
00:08:46
They can live on land or in water.
00:08:53
For celophods, they have a large head with tentacles.
00:08:58
Some have a shell for protection.
00:09:10
They live in water.
00:09:17
Some use camouflage.
00:09:20
So, for bivalves, some have two shells for protection.
00:09:27
They live in water.
00:09:36
Mirror word.
00:09:42
Group two, mollusks.
00:09:45
Mollusks have soft body. Gastropods, they have two eyes and, oh sorry, they have two antennae with eyes.
00:09:47
Some have a shell for protection. They can live on land or in water.
00:10:05
Cephalopods. They have a large head with tentacles.
00:10:19
Some have a shell for protection.
00:10:30
They live in water.
00:10:37
Some use camouflage.
00:10:43
Bivalves.
00:10:48
Some have two shells for protection.
00:10:50
They live in water.
00:10:56
Okay, this time, let's have some quick quiz game, yeah?
00:11:03
So, you figure out if it's anthropod or mollusk.
00:11:10
Spider, what do you think?
00:11:14
Are spiders arthropods or mollusks?
00:11:16
They are arthropods.
00:11:22
How about snails?
00:11:25
oh snails they are mollusks how about beetles okay they are arthropods
00:11:27
how about oh okay octopus okay it's there mollusks because they are cephalopods
00:11:42
how about butterfly
00:11:53
okay they are arthropods how about crabs okay they are arthropods how about squids okay they
00:11:54
are mollusk and they are cephalopods how about seahorse okay fish vertebrates vertebrates how
00:12:12
scorpions okay they are arthropods and how about oyster they are mollusks and
00:12:28
they are bivalves okay that's it for our practice and see you soon
