Welcome to MooMooMath and Science.
00:00:00
In this video I would like to talk about mollusks which are a type of invertebrate.
00:00:03
More specifically I would like to talk about the three major types of mollusks.
00:00:11
I will focus on gastropods, bivalves and cephalopods.
00:00:18
All mollusks have a soft body and bilateral symmetry.
00:00:26
Almost all have a toothed tongue called a radula.
00:00:31
And almost all have a muscular foot and or tentacles.
00:00:35
Up first are the gastropods.
00:00:42
With gastropods, their stomach lies above their foot.
00:00:46
Many have an external shell.
00:00:51
And examples include snails and slugs.
00:00:53
The second group I would like to look at are the bivalves.
00:01:13
These mollusks have two shells.
00:01:19
They do not have a head and most are filter feeders and examples include clam, oysters,
00:01:22
mussels and scallops.
00:01:28
And finally, let's take a look at the cephalopods.
00:01:50
Cephalopods have a prominent head, body, foot and a set of arms or tentacles.
00:01:57
They have three hearts, a brain, blue blood, and many can change colors.
00:02:02
Examples include an octopus, squid, and cuttlefish.
00:02:07
