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
